Our Business

We are a performance beauty company with a customer-centric approach focused on delivering breakthrough products in the self-pay aesthetic market. On February 1, 2019, the U.S. Food and Drug Administration, or FDA, approved our first product Jeuveau™ (prabotulinumtoxinA-xvfs). We plan to launch Jeuveau™ commercially in the United States in Spring 2019. Jeuveau™ is a proprietary 900 kDa purified botulinum toxin type A formulation indicated for the temporary improvement in the appearance of moderate to severe glabellar lines, also known as “frown lines,” in adults. We believe we will offer physicians and consumers a compelling value proposition with Jeuveau™. Currently, onabotulinumtoxinA (BOTOX) is the neurotoxin market leader, and prior to the approval of Jeuveau™, was the only known 900 kDa botulinum toxin type A complex approved in the United States. We believe aesthetic physicians generally prefer the performance characteristics of the complete 900 kDa neurotoxin complex and are accustomed to injecting this formulation.

We have successfully completed a comprehensive global five-study clinical development program which we named TRANSPARENCY. The TRANSPARENCY global clinical program included studies in the United States, European Union, or EU, and Canada to meet the regulatory requirements for a Biologics License Application, or BLA, in the United States, a Marketing Authorization Application, or MAA, in the EU, and a New Drug Submission, or NDS, in Canada, for the treatment of moderate to severe glabellar lines between the eyebrows. The program, which was developed in consultation with the FDA, Canadian and European regulatory bodies, included three multicenter, randomized, controlled, single dose Phase III studies and two open label, multiple dose, long-term Phase II studies. Over 2,100 adult male and female subjects with moderate to severe glabellar lines at maximum frown participated in the TRANSPARENCY program. All three Phase III studies in the TRANSPARENCY program successfully met their respective primary endpoints.

In August 2018 we received approval from Health Canada for the temporary improvement in the appearance of moderate to severe glabellar lines in adult patients under 65 years of age. We plan to begin to market the product in Canada in the second half of 2019 through our distribution partner Clarion Medical Technologies, Inc., or Clarion. We also submitted a Marketing Authorization Application, or MAA, to the European Medicines Agency, or EMA, and it was accepted for review in July 2017. In April 2019, the Committee for Medicinal Products for Human Use, or CHMP, adopted a positive opinion, recommending marketing authorization for the product.  The CHMP recommendation will be reviewed by the European Commission, which has the authority to approve medicines for the European Union and we anticipate that we will receive approval of our MAA within 90 days of the CHMP opinion.

We have never generated revenue from Jeuveau™ and have never been profitable. As of March 31, 2019, we had an accumulated deficit of approximately $134.0 million. We recorded a net loss and comprehensive loss of $11.0 million and $6.2 million for the three months ended March 31, 2019 and 2018.

Our market is the self-pay aesthetic market, which includes medical products purchased by physicians that are then sold to consumers or used in procedures for aesthetic indications that are not reimbursed by any third-party payor, such as Medicaid, Medicare or commercial insurance. Within the self-pay aesthetic market, the global aesthetic neurotoxin market was estimated to generate approximately $2.5 billion of revenue in 2018 and is estimated to grow to approximately $3.5 billion in 2021. The United States is the largest portion of this market and was estimated to generate approximately $1.2 billion of revenue in 2018 and is expected to grow to approximately $1.7 billion in 2021. We believe the aesthetic neurotoxin market is

S-2

one of the most attractive in healthcare with secular growth trends. We believe the continued growth of the aesthetic neurotoxin market will be driven by an aging population, increased use by individuals between the ages of 19 and 34, whom we refer to as millennials, increasing life expectancy, rising disposable income, improved accessibility to these products and treatments due to an increase in the number of physicians who perform these procedures, continued innovation, and an increasing acceptance and utilization of elective or minimally invasive aesthetic procedures. According to the American Society for Aesthetic Plastic Surgery, aesthetic neurotoxin treatments are the number one cosmetic procedure being considered by millennials, and neurotoxin use among this group has increased by 87% between 2011 and 2016.

Jeuveau™ is the first known neurotoxin dedicated exclusively to aesthetics. We plan to launch Jeuveau™ in the United States in Spring 2019 through our own specialty sales force of approximately 140 sales representatives. We intend to create a strongly desirable experience for physicians and consumers by leveraging our management team’s extensive industry experience, our compelling head-to-head clinical data compared with BOTOX, and our unique technology platform designed to transform the aesthetic market by eliminating the friction points existing for customers today. Outside of the United States, we plan to market and sell our neurotoxin through distributors in the territories in which we have the right to sell it.

We have entered into a license and supply agreement, or the Daewoong Agreement, pursuant to which we have an exclusive distribution license to Jeuveau™ from Daewoong Pharmaceuticals Co., Ltd., or Daewoong, a South Korean pharmaceutical manufacturer, for aesthetic indications in the United States, EU, Canada, Australia, Russia, Commonwealth of Independent States, or C.I.S., and South Africa, as well as co-exclusive distribution rights with Daewoong in Japan. Jeuveau™ will be manufactured by Daewoong in a recently constructed facility in South Korea. We also have the option to negotiate first with Daewoong to secure a distribution license for any product that Daewoong directly or indirectly develops or commercializes that is classified as an injectable botulinum toxin (other than Jeuveau™) in a territory covered by the license.

Our Competitive Strengths

We believe we will offer physicians and consumers a compelling value proposition beginning with the launch of Jeuveau™ for the following reasons:

• Jeuveau™ will offer the U.S. market the first known 900 kDa neurotoxin alternative to BOTOX. The manufacture of both Jeuveau™ and BOTOX starts with a 900 kDa complex, includes adding the excipients human serum albumin, or HSA, and sodium chloride, and finishes by vacuum drying. We believe Jeuveau™ is the only known neurotoxin product in the United States with a 900 kDa neurotoxin complex other than BOTOX. We also believe an important component of competitiveness in the neurotoxin market relates to the characteristics associated with the 900 kDa complex and the potential of the accessory proteins to increase the effectiveness of the active toxin portion of the complex.

• Results from our TRANSPARENCY global clinical program in more than 2,100 patients provides robust data to physicians evaluating the purchase of Jeuveau™. We believe the comprehensive TRANSPARENCY clinical data set, including a head-to-head Phase III study comparing Jeuveau™ and BOTOX,provides physicians with confidence in recommending Jeuveau™ to their patients.

• Enhanced level of physician-customer interaction through a self-pay, aesthetic-only marketing strategy. We have elected to specifically target the self-pay aesthetic market. With a reduced regulatory burden compared to third-party payor reimbursed therapeutic products, we believe we will achieve a number of benefits that market participants in reimbursed markets are unable to achieve, such as an enhanced level of interaction with our physician-customers. Jeuveau™ is the only U.S. neurotoxin without a therapeutic indication. We believe pursuing an aesthetic-only non-reimbursed product strategy will create meaningful strategic advantages in the United States, including pricing and marketing flexibility. We intend to utilize this flexibility to drive market adoption through programs such as promotional events, experience product programs and pricing strategies.

• We are building a unique technology platform. We intend to create a simple, personal and connected experience for physicians utilizing our proprietary technology platform. We are designing a platform with the goal of limiting friction and enhancing the overall experience for physicians and ultimately consumers.

• We have strong relationships with aesthetic key opinion leaders, or KOLs. We have established relationships with aesthetic KOLs as a result of our management team’s industry experience and engagement of our clinical trial investigators. KOLs are important information resources to the general physician-customer market due to their

S-3

clinical expertise, academic reputations, active clinical practices and their status as medical innovators. The broader physician community often looks to KOLs for their experience with products and procedures as part of their new product and procedure adoption process.

• Our management team has significant experience and expertise in medical aesthetics. Our management team has extensive experience in self-pay healthcare markets, in the development, market launch and commercialization of major medical products, execution and integration of business development transactions, identification of, and partnerships with, KOLs, and understanding of the regulatory environment of the healthcare markets. Key members of our leadership team have also served in relevant senior leadership positions with leading aesthetic companies.

Our Strategy

Our near-term strategy is to enter the U.S. medical aesthetic neurotoxin market with Jeuveau™. We plan to expand our product offerings over time through in-licensing, partnerships and acquisitions. The key components of our strategy are:

• Launch Jeuveau™ in the United States with our own specialty sales force of approximately 140 sales representatives.

• Partner outside of the United States to reach and serve physicians and consumers in those territories.

• Pursue an aesthetic-only strategy to enhance marketing and pricing flexibility along with improving transparency for our customers.

• Leverage our strong KOL relationships to assist in scientific presentations, publications, and other methods to drive success of our commercial launch of Jeuveau™.

• Establish a leading medical aesthetics company by in-licensing technology, developing partnerships and potentially acquiring products.

Our Market

Our market is self-pay aesthetic healthcare, which includes medical products purchased by physicians that are then sold to consumers or used in procedures for aesthetic indications that are not reimbursed by any third-party payor, such as Medicaid, Medicare or commercial insurance. By focusing on the self-pay medical aesthetics market, we believe we will not be exposed to reimbursement risk associated with a reliance on payments from such third-party payors, and we will be subject to fewer regulations that place limits on the types of marketing and other interactions we can have with physicians.

Within the self-pay aesthetic market, the global aesthetic neurotoxin market was estimated to generate approximately $2.5 billion of revenue in 2018 and is estimated to grow to approximately $3.5 billion in 2021. The U.S. aesthetic neurotoxin market was estimated to generate $1.2 billion in sales in 2018.

Within the multiple age groups that receive aesthetic neurotoxin treatments, we will strategically focus our marketing efforts on the millennial segment which is the largest cohort in the U.S. population. In 2019 there are estimated to be approximately 73 million millennials, defined as individuals born between 1981 and 1996. Botulinum toxin use among individuals between the age of 19 and 34 increased 87% between 2011 and 2016, and neurotoxin treatments are the number one cosmetic procedure considered by this generation. Approximately 1.7 million females between the age of 30 and 39, which includes many individuals we define as millennials, are considering neurotoxins in the next twelve months.

We believe the growth in the medical aesthetics market is driven by a number of factors, including:

• millennials are increasingly seeking medical aesthetic treatments and utilizing neurotoxins as an entry point for aesthetic procedures due to their minimally invasive nature;

• an aging population together with an increasing life expectancy, which is resulting in more consumers with a desire for improved appearance and well-being over a longer period of time;

S-4

• rising disposable income, with the U.S. Bureau of Economic Analysis reporting that real disposable income in the United States increased approximately 15% from March 2012 to March 2018;

• growing awareness, utilization and acceptance of elective or minimally invasive aesthetic procedures; and

• continued innovation and improved accessibility to these treatments due to an increase in the number of physicians who perform these procedures.

Currently, BOTOX, Dysport and Xeomin represent a majority of the medical aesthetics botulinum toxin type A market. In 2018, BOTOX U.S. unit market share was approximately 75% and generated approximately $907 million of revenue. In the same year, Dysport and Xeomin U.S. unit market share was approximately 19% and 7%, respectively.

Jeuveau™ Overview

We licensed Jeuveau™ from Daewoong in September 2013 and commenced clinical trials in 2014. Jeuveau™ is an injectable formulation of a 900 kDa botulinum toxin type A complex designed to address the needs of the large and growing facial aesthetics market.

Jeuveau™ contains a 900 kDa botulinum toxin type A complex produced by the bacterium Clostridium botulinum. The active part of the neurotoxin is the 150 kDa component, and the remaining 750 kDA of the complex is made up of accessory proteins that we believe help with the function of the active portion of the toxin. Jeuveau™ has the same mechanism of action as other type A botulinum toxins. When injected intramuscularly at therapeutic doses, botulinum toxin causes a chemical denervation of the muscle resulting in localized reduction of muscle activity. Botulinum toxin type A specifically blocks peripheral acetylcholine release at presynaptic cholinergic nerve terminals by cleaving SNAP-25, a protein integral to the successful docking and release of acetylcholine from vesicles situated within the nerve endings leading to denervation and relaxation of the muscle.

Controlled Company

We are presently a “controlled company” under the Nasdaq Marketplace Rules as a result of the ownership by ALPHAEON Corporation, or ALPHAEON, of a majority of our shares, which entitles us to rely on certain exemptions from Nasdaq’s corporate governance requirements. ALPHAEON, as the selling stockholder, is selling 4,000,000 shares of our common stock in this offering. Following this offering, ALPHAEON will no longer own 50% or more of our outstanding common stock, and therefore, we will cease to be a “controlled company” under the Nasdaq Marketplace Rules.

Implications of Being an Emerging Growth Company

We qualify as an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. For as long as we remain an emerging growth company, we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies. These provisions include, but are not limited to:

• being permitted to have only two years of audited financial statements and only two years of related selected financial data and management’s discussion and analysis of financial condition and results of operations disclosure;

• an exemption from compliance with the auditor attestation requirement in the assessment of our internal control over financial reporting pursuant to the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act;

• reduced disclosure about executive compensation arrangements in our periodic reports, registration statements and proxy statements; and

• exemptions from the requirements to seek non-binding advisory votes on executive compensation or golden parachute arrangements.

In addition, the JOBS Act permits emerging growth companies to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have elected to “opt out” of this provision and to comply with new or revised accounting standards as required of publicly-traded companies generally. This decision to opt out of the extended transition period is irrevocable.

S-5

We will remain an emerging growth company until the earliest of (i) December 31, 2023, (ii) the first fiscal year after our annual gross revenues exceed $1.07 billion, (iii) the date on which we have, during the immediately preceding three-year period, issued more than $1.0 billion in non-convertible debt securities or (iv) the end of any fiscal year in which the market value of our common stock held by non-affiliates exceeds $700 million as of the end of the second quarter of that fiscal year.

S-7

RISK FACTORS

An investment in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below and set forth under the heading “Risk Factors” on page 5 of the accompanying prospectus. You should also consider the risks, uncertainties and assumptions set forth under the heading “Risk Factors” in our 2018 Annual Report and our 2019 Quarterly Report, which are incorporated by reference into this prospectus supplement and the accompanying prospectus. You should carefully consider the following information about these risks, together with the other information appearing elsewhere in this prospectus supplement or the accompanying prospectus or incorporated by reference into this prospectus supplement or the accompanying prospectus, including our financial statements, the notes thereto and the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2018 Annual Report and our 2019 Quarterly Report before deciding to invest in our common stock. The occurrence of any of the these risks could have a material and adverse effect on our business, reputation, financial condition, results of operations and future growth prospects, as well as our ability to accomplish our strategic objectives. As a result, the trading price of our common stock could decline and you could lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations and stock price.

Risks Related to this Offering

Following this offering, we will no longer be a“controlled company”within the meaning of the Nasdaq Marketplace Rules. Prior to this offering, we qualified for, and relied on, exemptions from certain corporate governance requirements and our stockholders were not afforded the same protections as the stockholders of companies that are subject to such requirements.

Following this offering, ALPHAEON will no longer control a majority of the voting power of our outstanding common stock. As a result, we will no longer be a “controlled company” within the meaning of the corporate governance standards of the Nasdaq Marketplace Rules. Under these rules, a listed company of which more than 50% of the voting power is held by an individual, group or another company is a “controlled company” and may elect not to comply with certain corporate governance requirements, including:

• the requirement that a majority of our board of directors consist of independent directors;

• the requirement that our nominating and corporate governance committee be comprised entirely of independent directors with a written charter addressing the committee's purpose and responsibilities;

• the requirement that our compensation committee be comprised entirely of independent directors with a written charter addressing the committee's purpose and responsibilities; and

• the requirement for an annual performance evaluation of our nominating and corporate governance and compensation committees;

Prior to this offering, because we utilized certain of these exemptions, our nominating and corporate governance and compensation committees do not consist entirely of independent directors. After this offering, we will be required to comply with the above-referenced requirements within one year. We may have difficulty complying with the requirements listed above and while we intend to do so, we cannot assure you that we will be able to comply with such requirements before the end of the phase-in period for compliance. Accordingly, unless and until we comply with these requirements, you will not have the same protections afforded to stockholders of companies that are subject to and in compliance with all of the corporate governance requirements of Nasdaq.

UNDERWRITING

Morgan Stanley & Co. LLC is acting as the underwriter for this offering. Under the terms and subject to the conditions in an underwriting agreement dated the date of this prospectus supplement, among us, the underwriter and the selling stockholder, the underwriter has agreed to purchase, and the selling stockholder has agreed to sell to it the number of shares indicated below:

Name	Number of Shares
Morgan Stanley & Co. LLC	4,000,000
Total:	4,000,000

The underwriter is offering the shares of common stock subject to its acceptance of the shares from the selling stockholder and subject to prior sale. The underwriting agreement provides that the obligations of the underwriter to pay for and accept delivery of the shares of common stock offered by this prospectus supplement are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriter is obligated to take and pay for all of the shares of common stock offered by this prospectus supplement if any such shares are taken. However, the underwriter is not required to take or pay for the shares covered by the underwriter’s option to purchase additional shares described below.

The selling stockholder has granted to the underwriter an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to 600,000 additional shares of common stock at the price listed on the cover page of this prospectus supplement.

The underwriter has agreed to purchase the shares of our common stock offered by this prospectus supplement at a price of $       per share, which will result in approximately $       million of total net proceeds to the selling stockholder before expenses payable by the selling stockholder (or approximately $      million if the underwriter’s option to purchase additional shares of common stock is exercised in full). The underwriter proposes to offer the shares of common stock offered hereby from time to time for sale in one or more transactions on Nasdaq, in the over-the-counter market, through negotiated transactions or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices, subject to receipt and acceptance by it and subject to its right to reject any order in whole or in part. The underwriter may effect such transactions by selling the shares of common stock to or through dealers and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriter and/or purchasers of shares of common stock for whom it may act as agents or to whom it may sell as principal. The difference between the price at which the underwriter purchases shares and the price at which the underwriter resells such shares may be deemed underwriting compensation.

The estimated offering expenses payable by us are approximately $      . We have agreed to reimburse the underwriter for expense relating to clearance of this offering with the Financial Industry Regulatory Authority up to $10,000.

Our common stock is listed on the NASDAQ Global Market under the trading symbol “EOLS.”

We and all of our directors and officers and the selling stockholder have agreed that, without the prior written consent of Morgan Stanley & Co. LLC, we and they will not, during the period ending 60 days after the date of this prospectus supplement (the “restricted period”):

• offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any shares of common stock or any securities convertible into or exercisable or exchangeable for shares of common stock;

• file any registration statement with the SEC relating to the offering of any shares of common stock or any securities convertible into or exercisable or exchangeable for common stock; or

• enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the common stock.

whether any such transaction described above is to be settled by delivery of common stock or such other securities, in cash or otherwise. In addition, we and each such person have agreed that, without the prior written consent of Morgan Stanley & Co.

S-13

LLC, we or such other person will not, during the restricted period, make any demand for, or exercise any right with respect to, the registration of any shares of common stock or any security convertible into or exercisable or exchangeable for common stock.

The exceptions to our lock-up include: (A) the issuance or sale of any shares of our common stock to effectuate this offering, (B) the issuance of any shares, the grant of any options to purchase shares or the issuance of any shares upon the exercise of options, pursuant to any stock option, stock bonus or other stock plan or arrangement described herein, but only if the holders agree in writing not to sell, offer, dispose of or otherwise transfer any such shares or options during the 60-day period without the prior written consent of Morgan Stanley & Co. LLC, (C) the filing of a registration statement on Form S-8 relating to the stock option, stock bonus or other stock plans or arrangements, (D) assisting any of our stockholders in the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of our common stock, subject to certain exceptions and (E) the issuance of any shares of our common stock or securities convertible into shares of our common stock in connection with an acquisition or business combination (including the filing of a registration statement on Form S-4 or other appropriate form with respect thereto), so long as the purpose of such issuance is not solely for capital raising.

The exceptions to the lock-up for our directors, executive officers, and ALPHAEON, as the selling stockholder, are: (A) if such person is a natural person, transfers of shares of our common stock: (i) by gift, (ii) by will or intestacy, (iii) to any trust for the direct or indirect benefit of such person or the immediate family of such person or (iv) to any immediate family member; (B) if such person is a business entity, (i) transfers to such person’s affiliates that are business entities or (ii) distributions to limited partners, limited liability company members or stockholders of such person or holders of similar equity interests, provided that in each case such transfer or distribution does not involve a disposition for value; (C) if such person is a trust, transfers to the beneficiary of such trust; (D) transfers to any investment fund or other entity controlled or managed by such person; (E) transfers to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (A) through (D) above; (F) transfers to our company (i) pursuant to the exercise of options, through a “cashless” or “net exercise” basis, pursuant to our employee benefit plans or arrangements described in our public filings, provided that the lock-up provision shall apply to any securities issued upon any of these events or (ii) for the purpose of satisfying tax withholding requirements upon the vesting or exercise of restricted stock awards granted under an employee benefit plan or arrangement described in our public filings; (G) transfers pursuant to an order of a court or regulatory agency; (H) transfers of shares of our common stock acquired in open market transactions after the completion of this offering; (I) transfer of shares of our common stock pursuant to a bona fide third-party takeover bid, merger, consolidation or other similar transaction whereby all or substantially all the shares of our common stock are acquired by a third party, provided that, in the event such takeover, merger, consolidation, stock exchange or other similar transaction is not consummated or completed, the undersigned’s Shares or Related Securities will continue to be subject to the terms of this lock-up agreement; (J) with respect to the lock-up for ALPHAEON, transfers to Longitude Venture Partners II, L.P., Dental Innovations BVBA, or any of their successors, transferees and assigns, upon default under the ALPHAEON security agreements, provided that ALPHAEON will promptly notify Morgan Stanley & Co. LLC of any such default or transfer; (K) with respect to the lock-up for ALPHAEON, distributions of shares of our common stock to outstanding holders of its convertible promissory notes, in full or partial satisfaction of such notes, provided that each holder that receives more than 500 shares of our common stock executes and delivers to Morgan Stanley & Co. LLC, or already has in effect, a lock-up agreement; and (L) with respect to the lock-up for ALPHAEON, pledges and grants of security interests and transfers of shares to lenders or collateral agents, or any successors, transferees and assigns, upon default under, and pursuant to the terms of pledge or security agreements entered into after the date hereof in connection with debt obligations; provided that the undersigned shall promptly notify Morgan Stanley & Co. LLC of any such default or transfer, provided that in the case of any transfer or distribution pursuant to (A), (B), (C), (D), or (E) above, each transferee executes and delivers to Morgan Stanley & Co. LLC, or already has in effect, a lock-up agreement on terms substantially similar to the terms of the lock-up agreement described herein with respect to such securities and, in the case of any transfer or distribution pursuant to (A), (B), (C), (D), (E) or (H) above, no public disclosure or filing under the Exchange Act by any party to the transfer shall be required, or made voluntarily, reporting a reduction in beneficial ownership of shares of our common stock in connection with such transfer. There is a further exception to the lock-up for certain of our officers with respect to transfers of shares of common stock, or the withholding of shares of common stock, solely in connection with the payment of taxes due with respect to the vesting or settlement of restricted stock units granted under an employee benefit plan or arrangement described in our public filings.

Morgan Stanley & Co. LLC, in its sole discretion, may release the common stock and other securities subject to the lock-up agreements described above in whole or in part at any time.

In order to facilitate the offering of the common stock, the underwriter may engage in transactions that stabilize, maintain or otherwise affect the price of the common stock. Specifically, the underwriter may sell more shares than it is obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the number of shares available for purchase by the underwriter under the option. The underwriter can close out a covered

S-14

short sale by exercising the option or purchasing shares in the open market. In determining the source of shares to close out a covered short sale, the underwriter will consider, among other things, the open market price of shares compared to the price available under the option. The underwriter may also sell shares in excess of the option, creating a naked short position. The underwriter must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means of facilitating this offering, the underwriter may bid for, and purchase, shares of common stock in the open market to stabilize the price of the common stock. These activities may raise or maintain the market price of the common stock above independent market levels or prevent or retard a decline in the market price of the common stock. The underwriter is not required to engage in these activities and may end any of these activities at any time.

We, the selling stockholder and the underwriter have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

A prospectus supplement in electronic format may be made available on websites maintained by the underwriter, or selling group members, if any, participating in this offering. The underwriter may agree to allocate a number of shares of common stock for sale to its online brokerage account holders.

The underwriter and its affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. The underwriter and its affiliates may in the future perform various financial advisory and investment banking services for us, for which they would receive customary fees and expenses.

In addition, in the ordinary course of their various business activities, the underwriter and its affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investment and securities activities may involve our securities and instruments. The underwriter and its affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

We are a performance beauty company with a customer-centric approach focused on delivering breakthrough products in the self-pay aesthetic market. On February 1, 2019, the U.S. Food and Drug Administration, or FDA, approved our first product Jeuveau™ (prabotulinumtoxinA-xvfs). We plan to launch Jeuveau™ commercially in the United States in Spring 2019. Jeuveau™ is a proprietary 900 kDa purified botulinum toxin type A formulation indicated for the temporary improvement in the appearance of moderate to severe glabellar lines, also known as “frown lines,” in adults. We believe we will offer physicians and consumers a compelling value proposition with Jeuveau™. Currently, onabotulinumtoxinA (BOTOX) is the neurotoxin market leader, and prior to the approval of Jeuveau™, was the only known 900 kDa botulinum toxin type A complex approved in the United States. We believe aesthetic physicians generally prefer the performance characteristics of the complete 900 kDa neurotoxin complex and are accustomed to injecting this formulation.

We have successfully completed a comprehensive global five-study clinical development program which we named TRANSPARENCY. The TRANSPARENCY global clinical program included studies in the United States, EU and Canada to meet the regulatory requirements for a Biologics License Application, or BLA, in the United States, a Marketing Authorization Application, or MAA, in the European Union, or EU, and a New Drug Submission, or NDS, in Canada, for the treatment of moderate to severe glabellar lines between the eyebrows. The program, which was developed in consultation with the FDA, Canadian and European regulatory bodies, included three multicenter, randomized, controlled, single dose Phase III studies and two open label, multiple dose, long-term Phase II studies. Over 2,100 adult male and female subjects with moderate to severe glabellar lines at maximum frown participated in the TRANSPARENCY program. All three Phase III studies in the TRANSPARENCY program successfully met their respective primary endpoints.

We submitted a New Drug Submission, or NDS, to Health Canada and in August 2018 we received approval from Health Canada for the temporary improvement in the appearance of moderate to severe glabellar lines in adult patients under 65 years of age. We plan to market the product in Canada in the first half of 2019 through our distribution partner Clarion Medical Technologies, Inc., or Clarion, a Canadian provider of medical and aesthetic equipment and consumables to hospitals, aesthetic clinics and private medical practices. We also submitted an MAA to the European Medicines Agency, or EMA, and it was accepted for review in July 2017. We expect an opinion from the Committee for Medicinal Products for Human Use, or CHMP, in the first quarter of 2019. If the CHMP provides a favorable opinion, we would expect approval of our MAA by end of second quarter 2019.

Our primary market is the self-pay aesthetic market, which includes medical products purchased by physicians that are then sold to consumers or used in procedures for aesthetic indications that are not reimbursed by any third-party payor, such as Medicaid, Medicare or commercial insurance. Within the self-pay aesthetic market, the global aesthetic neurotoxin market was estimated to generate approximately $2.5 billion of revenue in 2018 and is estimated to grow to approximately $3.5 billion in 2021. The United States is the largest portion of this market and was estimated to generate approximately $1.2 billion of revenue in 2018 and is expected to grow to approximately $1.7 billion in 2021. We believe the aesthetic neurotoxin markets is one of the most attractive in healthcare with secular growth trends. We believe the continued growth of the aesthetic neurotoxin market will be driven by an aging population, increased use by individuals between the ages of 19 and 34, whom we refer to as millennials, increasing life expectancy, rising disposable income, improved accessibility to these products and treatments due to an increase in the number of physicians who perform these procedures, continued innovation, and an increasing acceptance and utilization of elective or minimally invasive aesthetic procedures. According to the American Society for Aesthetic Plastic Surgery, aesthetic neurotoxin treatments are the number one cosmetic procedure being considered by millennials, and neurotoxin use among this group has increased by 87% between 2011 and 2016.

Jeuveau™ is the first known neurotoxin dedicated exclusively to aesthetics. We plan to launch Jeuveau™ by building a commercialization infrastructure, which includes our own specialty sales force of approximately 140 sales representatives. We intend to create a strongly desirable experience for physicians and consumers by leveraging our management team’s extensive industry experience, our compelling head-to-head clinical data compared with BOTOX, and our unique technology platform designed to transform the aesthetic market by eliminating the friction points existing for customers today. Outside of the United States, we plan to market and sell our neurotoxin through distributors in the territories in which we have the right to sell it.

On September 30, 2013, we entered into a license and supply agreement, or the Daewoong Agreement, pursuant to which we have an exclusive distribution license to Jeuveau™ from Daewoong Pharmaceuticals Co., Ltd., or Daewoong, a South

2

Korean pharmaceutical manufacturer, for aesthetic indications in the United States, EU, Canada, Australia, Russia, Commonwealth of Independent States, or C.I.S., and South Africa, as well as co-exclusive distribution rights with Daewoong in Japan. Jeuveau™ will be manufactured by Daewoong in a recently constructed facility in South Korea. We also have the option to negotiate first with Daewoong to secure a distribution license for any product that Daewoong directly or indirectly develops or commercializes that is classified as an injectable botulinum toxin (other than Jeuveau™) in a territory covered by the license.

Controlled Company

We are presently a “controlled company” under the Nasdaq Marketplace Rules as a result of the ownership by ALPHAEON Corporation, or ALPHAEON, of a majority of our shares, which entitles us to rely on certain exemptions from Nasdaq’s corporate governance requirements. At such time as ALPHAEON no longer owns a majority of our shares, which could occur as a result of sales by ALPHAEON pursuant to the registration statement of which this prospectus forms a part, we will no longer be a “controlled company.” Because ALPHAEON is our controlling stockholder, it will be deemed to be an “underwriter” within the meaning of the Securities Act, with respect to any common stock offered by it pursuant to this prospectus, and any such offering would be deemed to be a primary offering by us.

Implications of Being an Emerging Growth Company

We qualify as an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. For as long as we remain an emerging growth company, we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies. These provisions include, but are not limited to:

• being permitted to have only two years of audited financial statements and only two years of related selected financial data and management’s discussion and analysis of financial condition and results of operations disclosure;

• an exemption from compliance with the auditor attestation requirement in the assessment of our internal control over financial reporting pursuant to the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act;

• reduced disclosure about executive compensation arrangements in our periodic reports, registration statements and proxy statements; and

• exemptions from the requirements to seek non-binding advisory votes on executive compensation or golden parachute arrangements.

In addition, the JOBS Act permits emerging growth companies to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have elected to “opt out” of this provision and to comply with new or revised accounting standards as required of publicly-traded companies generally. This decision to opt out of the extended transition period is irrevocable.

We will remain an emerging growth company until the earliest of (i) December 31, 2023, (ii) the first fiscal year after our annual gross revenues are $1.07 billion or more, (iii) the date on which we have, during the immediately preceding three-year period, issued more than $1.0 billion in non-convertible debt securities or (iv) the end of any fiscal year in which the market value of our common stock held by non-affiliates is $700 million or more as of the end of the second quarter of that fiscal year.

RISK FACTORS

Investing in our common stock involves significant risks. Before deciding whether to invest in our common stock, you should consider carefully the risks, uncertainties and assumptions described in this prospectus and any accompanying prospectus supplement, including the risk factors set forth in our filings with the SEC that are incorporated by reference herein and therein, including the risk factors in our most recent Annual Report on Form 10-K, as revised or supplemented by our Quarterly Reports on Form 10-Q, and as set forth below, which may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. If any of these risks actually occurs, our business, business prospects, financial condition or results of operations could be seriously harmed. Please also read carefully the section below entitled “Cautionary Note Regarding Forward-Looking Statements.”

Our certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our certificate of incorporation provides that, unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for all “internal corporate claims.” “Internal corporate claims” are claims that are based upon a violation of a duty by a current or former director, officer or stockholder in such capacity, or as to which Title 8 of the Delaware General Corporation Law, or DGCL, confers jurisdiction upon the Court of Chancery of the State of Delaware, or the Court of Chancery, in each case subject to the Court of Chancery having personal jurisdiction over the indispensable parties named as defendants and the claim not being one which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, or for which the Court of Chancery does not have subject matter jurisdiction. Any person purchasing or otherwise acquiring any interest in any shares of our capital stock shall be deemed to have notice of and to have consented to this provision of our certificate of incorporation. This choice of forum provision may limit our stockholders’ ability to bring a claim in a judicial forum that they find favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and our directors, officers, employees and agents even though an action, if successful, might benefit our stockholders. Stockholders who do bring a claim in the Court of Chancery could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near Delaware. The Court of Chancery may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments or results may be more favorable to us than to our stockholders. Alternatively, if a court were to find this provision of our certificate of incorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could have a material adverse effect on our business, financial condition or results of operations.

USE OF PROCEEDS

We will retain broad discretion over the use of the net proceeds from the sale of the securities offered hereby. Except as described in any applicable prospectus supplement we have authorized for use in connection with a specific offering, we currently intend to use the net proceeds from the sale of the securities offered by us hereunder, if any, for working capital and general corporate purposes. We may also use a portion of the net proceeds to acquire or invest in businesses, products and technologies that are complementary to our own, although we have no current commitments or agreements with respect to any acquisitions as of the date of this prospectus. We will set forth in the applicable prospectus supplement our intended use for the net proceeds received from the sale of any securities sold pursuant to the prospectus supplement. Pending the use of the net proceeds from any such offering, we may invest the net proceeds in investment grade, short-term interest-bearing obligations, such as money-market funds, certificates of deposit, or direct or guaranteed obligations of the United States government, or hold the net proceeds as cash.

Although ALPHAEON will be deemed to be an “underwriter” within the meaning of the Securities Act, with respect to any common stock offered by it pursuant to this prospectus, and any such offering will be deemed to be a primary offering by us, we will not receive any proceeds from any sale of the shares of our common stock offered by the selling stockholders, including by ALPHAEON. The selling stockholders will pay any underwriting discounts and commissions and expenses incurred by the selling stockholders for brokerage, accounting, tax or legal services or any other expenses incurred by the selling stockholders in disposing of their shares; provided, however, that we have agreed to pay reasonable fees and disbursements not to exceed $25,000 of a single special counsel for the selling stockholders in connection with this registration. We will bear all other costs, fees and expenses incurred in effecting the registration of the shares of common stock covered by this prospectus, including all registration and filing fees and fees and expenses of our counsel and accountants.

DIVIDEND POLICY

Since inception, we have never declared or paid any cash dividends on our capital stock and we do not currently intend to pay any cash dividends on our capital stock for the foreseeable future. We currently intend to retain all available funds and any future earnings to support our operations and finance the growth and development of our business. Any future determination related to our dividend policy will be made at the discretion of our board of directors and will depend upon, among other factors, our results of operations, financial condition, capital requirements, tax considerations, legal or contractual restrictions, business prospects, the requirements of current or then-existing debt instruments, general economic conditions and other factors our board of directors may deem relevant.

DESCRIPTION OF CAPITAL STOCK

The following is a summary of the rights of our common stock and preferred stock, certain provisions of our certificate of incorporation and our bylaws, and applicable law. This summary does not purport to be complete and is qualified in its entirety by the provisions of our certificate of incorporation and bylaws, copies of which are filed as exhibits to the registration statement of which this prospectus forms a part.

General

Our authorized capital stock consists of:

• 100,000,000 shares of common stock, par value $0.00001 per share; and

• 10,000,000 shares of preferred stock, par value $0.00001 per share.

As of December 31, 2018, there were 27,274,991 outstanding shares of our common stock. As of that date, there were outstanding options to purchase 3,257,801 shares of our common stock and 271,404 shares of common stock issuable upon the vesting and settlement of restricted stock units.

Common Stock

The following summarizes the rights of holders of our common stock:

Voting

The holders of our common stock are entitled to one vote per share. The number of authorized shares of common stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the voting power of our capital stock entitled to vote, irrespective of the provisions of Section 242(b)(2) of the Delaware General Corporation Law, or DGCL.

Dividends

Subject to preferences that may be applicable to the holders of outstanding shares of preferred stock, the holders of common stock are entitled to share equally, on a per share basis, in any dividends when, as and if declared by our board of directors out of assets legally available for dividends (except that in the event a dividend or distribution is paid in the form of common stock (or rights to acquire such stock), then holders of common stock shall receive common stock (or rights to acquire such stock, as the case may be).

As a Delaware corporation, we are subject to certain restrictions on dividends under the DGCL. Generally, a Delaware corporation may only pay dividends either out of “surplus” or out of the current or the immediately preceding year's net profits. Surplus is defined as the excess, if any, at any given time, of the total assets of a corporation over its total liabilities and statutory capital. The value of a corporation’s assets can be measured in a number of ways and may not necessarily equal their book value.

Liquidation Rights

Upon our liquidation, dissolution or winding up, after satisfaction of all our liabilities and the payment of any liquidation preference of any outstanding preferred stock, the holders of shares of common stock will be entitled to share equally, on a per share basis, in all of our assets legally remaining for distribution after payment of all debt and other liabilities.

Redemption Rights

There are no redemption or sinking fund provisions applicable to our common stock.

Preemptive Rights and Conversion Rights

There are no preemptive or conversion rights applicable to our common stock.

8

Preferred Stock

We have no shares of our preferred stock outstanding, but our board of directors is authorized, without further action by our stockholders, to create and issue one or more series of preferred stock and to fix the rights, powers, preferences and privileges thereof. Among other rights, our board of directors may determine, without further vote or action by our stockholders:

• the number of shares constituting the series and the distinctive designation of the series;

• the dividend rate on the shares of the series, whether dividends will be cumulative, and if so, from which date or dates, and the relative rights of priority, if any, of payment of dividends on shares of the series;

• whether the series will have voting rights in addition to the voting rights provided by law and, if so, the terms of the voting rights;

• whether the series will have conversion privileges and, if so, the terms and conditions of conversion;

• whether or not the shares of the series will be redeemable or exchangeable, and, if so, the dates, terms and conditions of redemption or exchange, as the case may be;

• whether the series will have a sinking fund for the redemption or purchase of shares of that series, and, if so, the terms and amount of the sinking fund; and

• the rights of the shares of the series in the event of our voluntary or involuntary liquidation, dissolution or winding up and the relative rights or priority, if any, of payment of shares of the series.

Any future issuance of shares of preferred stock, or the issuance of rights to purchase shares of preferred stock, could, among other things, decrease the amount of earnings and assets available for distribution to the holders of common stock or could adversely affect the rights and powers, including voting rights, of the holders of the common stock.

Equity Awards

As of December 31, 2018, there were 3,257,801 shares of common stock subject to outstanding stock options under our 2017 Omnibus Incentive Plan, or the 2017 plan. In addition, as of December 31, 2018, there were 271,404 shares of common stock issuable upon the vesting and settlement of restricted stock units outstanding under the 2017 plan.

Registration Rights

On December 14, 2017, we entered into a stockholders’ agreement with ALPHAEON, Dental Innovations BVBA, or DI, as collateral agent, and Longitude Venture Partners II, L.P., or Longitude, as a secured party, that provides ALPHAEON (and upon an event of default by ALPHAEON under certain convertible bridge note and convertible promissory notes, DI and Longitude) with registration rights relating to shares of our common stock held by ALPHAEON (and pledge to DI and Longitude).

At any time beginning 180 days after February 7, 2018, the date of the final prospectus in our initial public offering, ALPHAEON may request that we register for resale all or a portion of its shares of common stock. ALPHAEON may also request that we file an automatic shelf registration statement on Form S-3 that covers the registrable securities requested to be registered, to the extent we are eligible to do so. Depending on certain conditions, and in addition to other exclusions, we may defer a demand registration for up to 90 days in any twelve-month period.

In the event that we propose to register any of our securities under the Securities Act, either for our account or for the account of our other security holders, ALPHAEON is entitled to certain piggyback registration rights allowing it to include its shares in the registration, subject to certain marketing and other limitations. As a result, whenever we propose to file a registration statement under the Securities Act, such as the registration statement of which this prospectus is a part, ALPHAEON is entitled to notice of the registration and the right to include its shares in such registration.

9

The stockholders’ agreement provides that we must pay all registration expenses (other than the underwriting discounts and commissions) in connection with effecting any demand registration or shelf registration. The stockholders’ agreement contains customary indemnification and contribution provisions by us for the benefit of ALPHAEON and its affiliates and, in limited situations, by ALPHAEON for the benefit of us and any underwriters with respect to written information furnished to us by ALPHAEON and stated by ALPHAEON to be specifically included in any registration statement, prospectus or related document.

The registration rights remain in effect with respect to any shares covered by the stockholders’ agreement until (i) all such shares have been sold pursuant to an effective registration statement under the Securities Act, or (ii) such time as Rule 144 or another similar exemption under the Securities Act is available for the sale of all of the shares without limitation during a three-month period without registration.

In November 2018, ALPHAEON distributed a certain number of shares of our common stock that it held to certain of its noteholders in exchange for the extinguishment of outstanding debt obligations. As part of that distribution, such noteholders, including two of the selling stockholders included in this prospectus (DI and Alpha International Investment Ltd.), became parties to the stockholders’ agreement.

Anti-Takeover Effects of Provisions of our Certificate of Incorporation, Bylaws and Delaware Law

Delaware Anti-Takeover Law

From and after the date on which ALPHAEON no longer beneficially owns a majority of the voting power of all of the then-outstanding shares of our capital stock, we will be subject to Section 203 of the DGCL, or Section 203. Section 203 generally prohibits a public Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years following the time that such stockholder became an interested stockholder, unless:

• prior to such time the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

• upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (i) by persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

• at or subsequent to such time the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder.

In general, Section 203 defines a business combination to include:

• any merger or consolidation involving the corporation and the interested stockholder;

• any sale, transfer, pledge or other disposition involving the interested stockholder of 10% or more of the assets of the corporation;

• subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

• subject to exceptions, any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; and

• the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

10

In general, Section 203 defines an interested stockholder as any entity (other than the corporation and any direct or indirect majority-owned subsidiary of the corporation) or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with, associated with or controlling or controlled by such entity or person.

Certificate of Incorporation and Bylaws

The following provisions of our certificate of incorporation and bylaws may make a change-of-control of our company more difficult and could delay, defer or prevent a tender offer or other takeover attempt that a stockholder might consider to be in its best interest, including takeover attempts that might result in the payment of a premium to stockholders over the market price for their shares. These provisions also may promote the continuity of our management by making it more difficult for a person to remove or change the incumbent members of our board of directors.

Authorized but Unissued Shares; Undesignated Preferred Stock. The authorized but unissued shares of our common stock will be available for future issuance without stockholder approval, subject to applicable law and the Nasdaq Marketplace Rules. These additional shares may be used for a variety of corporate purposes, including future public offerings to raise additional capital, acquisitions and employee benefit plans. In addition, our board of directors may authorize, without stockholder approval, the issuance of undesignated preferred stock with voting rights or other rights or preferences designated from time to time by our board of directors (including the right to approve an acquisition or other change in our control). The existence of authorized but unissued shares of common stock or preferred stock may enable our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise.

Election and Removal of Directors. Our board of directors will consist of not less than five nor more than nine directors. The exact number of directors will be fixed from time to time only by resolution of our board of directors. Our board of directors currently has seven members.

From and after the date on which ALPHAEON no longer beneficially owns a majority of the voting power of all of the then-outstanding shares of our capital stock, our certificate of incorporation provides that directors may be removed only for cause and only by the affirmative vote of holders of at least 66 2/3% of our then outstanding voting stock. Prior to such time, our certificate of incorporation provides that directors may be removed only for cause and only by the affirmative vote of holders of at least a majority of our then outstanding voting stock.

Classified Board of Directors. Our certificate of incorporation provides that our board of directors are classified with approximately one-third of the directors elected each year. The authorized number of directors may be changed only by resolution of the board of directors. The directors are divided into three classes, designated class I, class II and class III. Each class consists, as nearly as may be possible, of one-third of the total number of directors constituting the entire board of directors. At each annual meeting of stockholders, successors to the class of directors whose term expires at that annual meeting will be elected until the third annual meeting of stockholders next succeeding the elections or until their successors are duly elected and qualified or until their earlier death, resignation or removal. In addition, if the number of directors is changed, any increase or decrease will be apportioned by our board of directors among the classes so as to maintain the number of directors in each class as nearly equal as possible, and any additional director of any class elected to fill a vacancy resulting from an increase in such class or from the removal from office, death, disability, resignation or disqualification of a director or other cause will hold office for a term that will coincide with the remaining term of that class, but in no case will a decrease in the number of directors have the effect of removing or shortening the term of any incumbent director.

Director Vacancies. Our certificate of incorporation authorizes only our board of directors to fill vacant directorships.

No Cumulative Voting. Our certificate of incorporation provides that stockholders do not have the right to cumulate votes in the election of directors (therefore allowing the holders of a majority of the shares of common stock entitled to vote in any election of directors to elect all of the directors standing for election, if they should so choose).

Special Meetings of Stockholders. Our certificate of incorporation and bylaws provide that special meetings of our stockholders may only be called by the chairman of the board, our Chief Executive Officer or by our board of directors pursuant to a resolution adopted by a majority of the total number of authorized directors.

Advance Notice Procedures for Director Nominations. Our bylaws establish advance notice procedures for stockholders seeking to nominate candidates for election as directors at an annual or special meeting of stockholders. Although our bylaws

11

do not give the board of directors the power to approve or disapprove stockholder nominations of candidates to be elected at an annual meeting, our bylaws may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed or may discourage or deter a potential acquiror from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempting to obtain control of us.

Action by Written Consent. Our certificate of incorporation provides that, from and after the date on which ALPHAEON no longer beneficially owns a majority of the voting power of all of the then-outstanding shares of our capital stock, any action required or permitted to be taken by the stockholders must be effected at a duly called annual or special meeting of stockholders and may not be effected by any consent in writing in lieu of a meeting of such stockholders, subject to the rights of the holders of any series of preferred stock.

Amending Our Certificate of Incorporation and Bylaws. At any time after ALPHAEON beneficially owns less than 50% of our then-outstanding capital stock, our certificate of incorporation and bylaws may be amended by the affirmative vote of the holders of at least 66 2/3% of the voting power of our then-outstanding common stock. Prior to such time, our certificate of incorporation and bylaws may be amended by the affirmative vote of the holders of a majority of the voting power of our then-outstanding capital stock.

Exclusive Jurisdiction. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery shall be the sole and exclusive forum for all “internal corporate claims.” “Internal corporate claims” are claims, (i) that are based upon a violation of a duty by a current or former director or officer or stockholder in such capacity, or (ii) as to which Title 8 of the DGCL confers jurisdiction upon the Court of Chancery, except for, as to each of (i) and (ii) above, any claim as to which the Court of Chancery determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination), which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, or for which the Court of Chancery does not have subject matter jurisdiction.

Conflicts of Interest

Delaware law permits corporations to adopt provisions renouncing any interest or expectancy in certain opportunities that are presented to the corporation or its officers, directors or stockholders. Our certificate of incorporation, to the maximum extent permitted from time to time by Delaware law, renounces any interest or expectancy that we have in, or right to be offered an opportunity to participate in, specified business opportunities that are from time to time presented to ALPHAEON or any of its officers, directors, stockholders, agents, members, partners, subsidiaries (other than our company) and affiliates, other than those directors and officers of our company who are offered business opportunities in their capacity as directors and officers of our company, or the specified parties. Our certificate of incorporation provides that, to the fullest extent permitted by law, none of the specified parties will have any duty to refrain from engaging in a corporate opportunity that we might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so.

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities from time to time, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in any applicable prospectus supplement or free writing prospectus. The terms of any debt securities offered under any applicable prospectus supplement may differ from the terms described below. Unless the context requires otherwise, whenever we refer to the indenture, we also are referring to any supplemental indentures that specify the terms of a particular series of debt securities.

We will issue the debt securities under the indenture that we will enter into with the trustee named in the indenture. The indenture will be qualified under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. We have filed the form of indenture as an exhibit to the registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.

The following summary of material provisions of the debt securities and the indenture is subject to, and qualified in its entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read any applicable prospectus supplements and any related free writing prospectuses related to the debt securities that we may offer under this prospectus, as well as the complete indenture that contains the terms of the debt securities.

General

The indenture does not limit the amount of debt securities that we may issue. It provides that we may issue debt securities up to the principal amount that we may authorize and may be in any currency or currency unit that we may designate. Except for the limitations on consolidation, merger and sale of all or substantially all of our assets contained in the indenture, the terms of the indenture do not contain any covenants or other provisions designed to give holders of any debt securities protection against changes in our operations, financial condition or transactions involving us.

We may issue the debt securities issued under the indenture as “discount securities,” which means they may be sold at a discount below their stated principal amount. These debt securities, as well as other debt securities that are not issued at a discount, may be issued with “original issue discount,” or OID, for U.S. federal income tax purposes because of interest payment and other characteristics or terms of the debt securities. One or more series of debt securities may be variable rate debt securities that may be exchanged for fixed rate debt securities. Material U.S. federal income tax considerations applicable to debt securities issued with OID will be described in more detail in any applicable prospectus supplement.

We will comply with Section 14(e) under the Exchange Act to the extent applicable, and any other tender offer rules under the Exchange Act, which may then be applicable, in connection with any obligation we may have to purchase debt securities at the option of the holders thereof. Any such obligation applicable to a series of debt securities will be described in any applicable prospectus supplement.

Any applicable prospectus supplement relating to a series of debt securities being offered will contain the following terms, if applicable:

• the title of the series of debt securities and the ranking;

• the aggregate principal amount and any limit on that amount;

• the price at which the debt securities will be issued;

• the date on which the debt securities mature;

• the fixed or variable rate at which the debt securities will bear interest, or the method by which the rate shall be determined;

13

• the timing, place and manner of making principal, interest and any premium payments on the debt securities, and, if applicable, where the debt securities may be surrendered for registration of transfer or exchange;

• the date or dates, if any, after which the debt securities may be converted or exchanged into or for our common stock or another company’s securities or property or cash, and the terms of any such conversion or exchange;

• any redemption or early repayment provisions;

• any sinking fund or similar provisions;

• the authorized denominations;

• any applicable subordination provisions;

• any guarantees of the securities by our subsidiaries or others;

• the currency in which we will pay the principal, interest and any premium payments on the debt securities;

• whether the amount of payments of principal of (and premium, if any) or interest, if any, on the debt securities may be determined with reference to an index, formula or other method and the manner in which the amounts shall be determined;

• the denominations in which we will issue the series of debt securities, if other than denominations of $1,000 and any integral multiple thereof;

• the time period within which, the manner in which and the terms and conditions upon which the purchaser of the securities can select the payment currency;

• the provisions, if any, granting special rights to the holders of debt securities upon certain events;

• any additions to or changes in the events of default or covenants with respect to the debt securities, and any change in the right of the trustee or the holders, from those described in this prospectus, to declare principal, premium and interest to be due and payable;

• additions to or changes in or deletions of the provisions relating to covenant defeasance and legal defeasance;

• additions to or changes in the provisions relating to satisfaction and discharge of the indenture;

• additions to or changes in the provisions relating to the modification of the indenture both with and without the consent of holders of debt securities issued under the indenture;

• whether and under what circumstances we will pay any additional amounts on the debt securities for any tax, assessment or governmental charge and, if so, whether we will have the option to redeem the debt securities instead of paying those amounts;

• the form (registered and/or bearer securities), any restrictions applicable to the offer, sale or delivery of bearer securities and the terms, if any, upon which bearer securities may be exchanged for registered securities and vice versa;

• the date of any bearer securities or any global security, if other than the date of original issuance of the first security of the series to be issued;

• the person to whom and manner in which any interest shall be payable;

• whether the securities will be issued in whole or in part in the form of one or more global securities;

• the identity of the depositary for global securities;

14

• whether a temporary security is to be issued with respect to the series and whether any interest payable prior to the issuance of definitive securities of the series will be credited to the account of the persons entitled thereto;

• the terms upon which beneficial interests in a temporary global security may be exchanged in whole or in part for beneficial interests in a definitive global security or for individual definitive securities and the terms upon which exchanges may be made;

• the securities exchange(s), if any, on which the securities will be listed;

• whether any underwriter(s) will act as market maker(s) for the securities;

• the form (certificated or book-entry);

• the form and/or terms of certificates, documents or conditions which may be necessary, if any, for the debt securities to be issuable in final form; and

• additional terms not inconsistent with the provisions of the indenture.

Conversion or Exchange Rights

We will set forth in any applicable prospectus supplement the terms on which a series of debt securities may be convertible into or exchangeable for our common stock or our other securities. We will include provisions as to settlement upon conversion or exchange and whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of our common stock or our other securities that the holders of the series of debt securities receive would be subject to adjustment.

Consolidation, Merger or Sale

Except as set forth in any applicable prospectus supplement, the indenture will provide that we shall not consolidate with, or sell, assign, transfer, lease or convey all or substantially all of our assets to, or merge into, another business entity, unless:

• we are the surviving entity or, in the event that we are not the surviving entity, the entity formed by the transaction (in a consolidation) or the entity which received the transfer of assets is organized under the laws of any state of the United States or the District of Columbia and that the entity assumes all of our obligations under the debt securities and the indenture; and

• immediately after giving effect to the transaction, no event of default, as defined in the indenture, shall have occurred and be continuing.

Notwithstanding the foregoing, we may merge with another business entity or acquire by purchase or otherwise all or any part of the property or assets of any other company in a transaction in which we are the surviving entity.

Events of Default

Unless otherwise specified in any applicable prospectus supplement, the following are events of default with respect to any series of debt securities issued under the indenture:

• failure to pay principal of any debt security of that series when due and payable at maturity, upon acceleration, redemption or otherwise;

• failure to pay any interest on any debt security of that series when due, and the default continues for 30 days;

• failure to make sinking fund payments when due;

• failure to comply with any covenant or warranty contained in the indenture, other than covenants or warranties contained in the indenture solely for the benefit of other series of debt securities, and the default continues for 30

15

days after notice from the trustee or the holders of at least 25% in principal amount of the then outstanding debt securities of that series;

• certain events of bankruptcy, insolvency or reorganization; and

• any other event of default provided with respect to that particular series of debt securities.

If an event of default occurs and continues, then upon written notice to us, the trustee or the holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the unpaid principal amount of and any accrued and unpaid interest on, all debt securities of that series to be due and payable immediately. However, at any time after a declaration of acceleration with respect to debt securities of any series has been made, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the acceleration:

• if all events of default other than the nonpayment of principal of or interest on the debt securities of that series which have become due solely because of the acceleration have been waived or cured; and

• the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. For information as to waiver of defaults, see “Modification of Indenture; Waiver” below.

The indenture will provide that, subject to the duty of the trustee during an event of default to act with the required standard of care, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders, unless the holders shall have offered to the trustee reasonable security or indemnity. Subject to certain provisions, including those requiring security or indemnification of the trustee, the holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the debt securities of that series.

We will be required to furnish to the trustee under the indenture annually a statement as to the performance by us of our obligations under that indenture and as to any default in our performance.

Modification of Indenture; Waiver

Subject to certain exceptions, the terms of the indenture or the debt securities may be amended or supplemented by us and the trustee with the written consent of the holders of at least a majority in principal amount of the outstanding debt securities of each series affected by the amendment with each series voting as a separate class. Without the consent of any holder of the debt securities, we and the trustee may amend the terms of the indenture or the debt securities to:

• cure any ambiguity, defect or inconsistency;

• provide for the assumption of our obligations to holders of the debt securities by a successor corporation;

• provide for uncertificated debt securities in addition to certificated debt securities;

• make any change that does not adversely affect the rights of any holder of the debt securities in any material respect;

• add to, change or eliminate any other provisions of the indenture in respect of one or more series of debt securities if the change would not (i) apply to any security of any series created prior to the execution of a supplemental indenture and entitled to the benefit of the provision, and (ii) modify the rights of the holder of any security or would become effective only when there is no outstanding security of any series created prior to the execution of the supplemental indenture and entitled to the benefits of the provisions proposed to be changed;

• establish any additional series of debt securities; or

• comply with any requirement of the SEC in connection with the qualification of the indenture under the Trust Indenture Act.

However, holders of each series of debt securities affected by a modification must consent to modifications that:

16

• reduce the principal amount of the debt securities;

• reduce the rate or change the time for payment of interest;

• change the fixed maturity date;

• change the date on which any debt security may be subject to redemption or repurchase, or reduce the redemption or repurchase price;

• make any debt security payable in currency other than that stated in the debt security;

• waive any existing default or event of default and the resulting consequences;

• modify the right of any holder to receive payment of principal or interest on any debt security;

• impair the right of any holder to institute suit for the enforcement of any payment due; or

• make any change in the foregoing amendment provisions which require each holder’s consent.

Any existing default may be waived with the consent of the holders of at least a majority in principal amount of the then outstanding debt securities of the series affected. The consent of the holders of debt securities is not necessary to approve the particular form of any proposed amendment to any indenture. It is sufficient if any consent approves the substance of the proposed amendment.

Covenants

Except as permitted in certain circumstances as discussed under “Consolidation, Merger or Sale,” the indenture will require us to do or cause to be done all things necessary to preserve and keep in full force and effect our existence, rights (declaration and statutory) and franchises; provided, however, that we shall not be required to preserve any right or franchise if we determine that the right or franchise is no longer desirable in the conduct of our business and that the loss of the right or franchise is not disadvantageous in any material respect to the holders of the debt securities.

The indenture will require us to pay or discharge or cause to be paid or discharged, before payment becomes delinquent, all taxes, assessments and governmental charges levied or imposed upon us, except any tax, assessment, charge or claim the amount or applicability of which is being contested in good faith.

Reference is made to the indenture and any applicable prospectus supplement for information with respect to any additional covenants specific to a particular series of debt securities.

Discharge

Except as otherwise set forth in any applicable prospectus supplement, we may terminate our obligations under the debt securities of any series, and the corresponding obligations under the indenture when:

• we have paid or deposited with the trustee funds or United States government obligations in an amount sufficient to pay at maturity all outstanding debt securities of the series, including interest other than destroyed, lost or stolen debt securities of the series which have not been replaced or paid;

• all outstanding debt securities of the series have been delivered (other than destroyed, lost or stolen debt securities of the series which have not been replaced or paid) to the trustee for cancellation;

• all outstanding debt securities of any series have become due and payable; or

• we have paid all other sums payable under the indenture.

In addition, we will have the option to terminate substantially all our obligations under the debt securities of any series and the corresponding obligations under the indenture, and we may exercise that option if:

17

• we have paid or deposited with the trustee, in trust an amount of cash or United States government obligations sufficient to pay all outstanding principal of and interest on the then outstanding debt securities of the series at maturity or upon their redemption, as the case may be;

• the deposit will not result in a breach of, or constitute a default under, the indenture;

• no default or event of default shall have occurred and continue on the date of deposit and no event of default as a result of a bankruptcy or event which with the giving of notice or the lapse of time would become a bankruptcy event of default shall have occurred and be continuing on the 91st day after that date;

• we deliver to the trustee a legal opinion that we have received from, or there has been published by, the United States Internal Revenue Service a ruling, or there has been a change in tax law, in either case to the effect that the holders of the debt securities of the series will not recognize income, gain or loss for Federal income tax purposes as a result of our exercise of our option and shall be subject to Federal income tax on the same amounts and in the same manner and at the same times as would have been the case if we did not exercise our option; or

• certain other conditions are met.

We will have the option to be released from our obligations with respect to the covenants to deliver reports required to be filed with the SEC and an annual compliance certificate, and to make timely payments of taxes (including covenants described in an applicable prospectus supplement), and any event of default occurring because of a default with respect to the covenants as they related to any series of debt securities, and we may exercise that option if:

• we deposit or cause to be deposited with the trustee in trust an amount of cash or United States government obligations sufficient to pay and discharge when due the entire unpaid principal of and interest on all outstanding debt securities of any series;

• the deposit will not result in a breach of, or constitute a default under, the indenture;

• no default or event of default shall have occurred and be continuing on the date of deposit and no event of default as a result of a bankruptcy or event which with the giving of notice or the lapse of time would become a bankruptcy event of default shall have occurred and be continuing on the 91st day after that date;

• we deliver to the trustee a legal opinion that the holders of the debt securities of the series will not recognize income, gain or loss for Federal income tax purposes as a result of our exercise of our option and shall be subject to Federal income tax on the same amounts and in the same manner and at the same times as would have been the case if we did not exercise our option; and

• certain other conditions are met.

Upon satisfaction of the applicable conditions, our obligations under the indenture with respect to the debt securities of the series, other than with respect to the covenants and events of default referred to above, shall remain in full force and effect.

Notwithstanding the foregoing, no discharge or defeasance described above shall affect the following obligations to or rights of the holders of any series of debt securities:

• rights of registration of transfer and exchange of debt securities of the series;

• rights of substitution of mutilated, defaced, destroyed, lost or stolen debt securities of the series;

• rights of holders of debt securities of the series to receive payments of principal thereof and premium, if any, and interest thereon when due;

• rights, obligations, duties and immunities of the trustee;

• rights of holders of debt securities of the series as beneficiaries with respect to property deposited with the trustee and payable to all or any of them; and

18

• our obligations to maintain an office or agency in respect of the debt securities of the series.

Form, Exchange and Transfer

We expect payment of principal, premium, if any, and any interest on the debt securities to be payable, and the exchange and the transfer of debt securities will be registrable, at the office of the trustee or at any other office or agency we maintain for that purpose. We expect to issue debt securities in denominations of U.S. $1,000 or integral multiples of $1,000. No service charge will be made for any registration of transfer or exchange of the debt securities, but we may require a payment to cover any tax or other governmental charges payable in connection with an exchange or transfer.

A holder of debt securities may transfer or exchange those debt securities in accordance with the indenture. The registrar for the debt securities may require a holder, among other things, to furnish appropriate endorsements and transfer documents, and to pay any taxes and fees required by law or permitted by the indenture. The registrar is not required to transfer or exchange any debt security selected for redemption or any debt security for a period of 15 days before a selection of debt security to be redeemed. The registered holder of a debt security may be treated as the owner of the security for all purposes.

We will name in any applicable prospectus supplement the security registrar, and any transfer agent in addition to the security registrar, that we initially designate for any debt securities. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

Replacement Securities

Any mutilated certificate representing a debt security or a certificate representing a debt security with a mutilated coupon will be replaced by us at the expense of the holder upon surrender of the certificate to the trustee. Certificates representing debt securities or coupons that become destroyed, stolen or lost will be replaced by us at the expense of the holder upon delivery to us and the trustee of evidence of any destruction, loss or theft satisfactory to us and the trustee, provided that neither we nor the trustee has been notified that the certificate or coupon has been acquired by a bona fide purchaser. In the case of any coupon which becomes destroyed, stolen or lost, the coupon will be replaced by issuance of a new certificate representing the debt security in exchange for the certificate representing the debt security to which the coupon appertains. In the case of a destroyed, lost or stolen certificate representing the debt security or coupon, an indemnity bond satisfactory to the trustee and us may be required at the expense of the holder of the debt security before a replacement certificate will be issued.

Information Concerning the Trustee

We will identify in any applicable prospectus supplement relating to any series of debt securities the trustee with respect to the series. The indenture and the Trust Indenture Act contain certain limitations on the rights of the trustee, should it become our creditor, to obtain payment of claims in certain cases, or to realize on certain property received in respect of any the claim, as security or otherwise. The trustee and its affiliates may engage in, and will be permitted to continue to engage in, other transactions with us and our affiliates, but if the trustee acquires any conflicting interest, as defined in the Trust Indenture Act, it must eliminate the conflict or resign.

The holders of a majority in principal amount of the then outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee. The Trust Indenture Act and the indenture provide that in case an event of default occurs is continuing, the trustee will be required, in the exercise of its rights and powers, to use the degree of care and skill of a prudent man in the conduct of his own affairs. Subject to those provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any of the holders of the debt securities, unless they have offered to the trustee indemnity satisfactory to it.

Global Debt Securities

Unless we indicate otherwise in any applicable prospectus supplement, the following provisions will apply to all debt securities.

The debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with a depositary that we will identify in any applicable prospectus supplement. Each global security will be

19

deposited with the depositary and will bear a legend regarding any related restrictions or other matters as may be provided for pursuant to the applicable indenture.

Unless any applicable prospectus supplement states otherwise, no global security may be transferred to, or registered or exchanged for, debt securities registered in the name of, any person or entity other than the depositary, unless:

• the depositary has notified us that it is unwilling or unable or is no longer qualified to continue as depositary;

• we order the trustee that the global security shall be so transferable, registrable and exchangeable, and the transfers shall be registrable; or

• other circumstances, if any, as may be described in any applicable prospectus supplement.

All debt securities issued in exchange for a global security or any portion of a global security will be registered in those names as the depositary may direct. The specific terms of the depositary arrangement with respect to any portion of a series of debt securities to be represented by a global security will be described in any applicable prospectus supplement.

Debt securities which are to be represented by a global security to be deposited with or on behalf of a depositary will be represented by a global security registered in the name of the depositary or its nominee. Upon the issuance of the global security, and the deposit of the global security with the depositary, the depositary will credit, on its book-entry registration and transfer system, the respective principal amounts of the debt securities represented by the global security to the accounts of institutions that have accounts with the depositary or its nominee, or the Participants. The accounts to be credited will be designated by the underwriters or agents of the debt securities or by us, if the debt securities are offered and sold directly by us.

Ownership of beneficial interests in a global security will be limited to Participants or persons that may hold interests through Participants. Ownership of beneficial interests in a global security will be shown on, and the transfer of that ownership interest will be effected only through, records maintained by the depositary or its nominee for the global security or by Participants or persons that hold through Participants.

The laws of some jurisdictions require that certain purchasers of securities take physical delivery of the securities in certificated form. Those laws may impair the ability to transfer beneficial interests in global securities.

So long as the depositary, or its nominee, is the registered owner of a global security, the depositary or the nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the indenture. Payment of principal of, and premium and interest, if any, on debt securities will be made to the depositary or its nominee as the registered owner or bearer as the case may be of the global security representing the debt securities. Each person owning a beneficial interest in a global security must rely on the procedures of the depositary and, if the person is not a Participant, on the procedures of the Participant through which the person owns its interest, to exercise any rights of a holder under the indenture. If we request any action of holders or if an owner of a beneficial interest in a global security desires to give any notice or take any action a holder is entitled to give or take under the indenture, the depositary will authorize the Participants to give the notice or take the action, and Participants would authorize beneficial owners owning through the Participants to give the notice or take the action or would otherwise act upon the instructions of beneficial owners owning through them.

The rights of any holder of a debt security to receive payment of principal and premium of, if any, and interest, on or after the respective due dates expressed or provided for in the debt security, or to institute suit for the enforcement of any payment on or after the applicable date, shall not be impaired or affected without the consent of the holders.

Neither we, the trustee, any paying agent nor the security registrar for a debt security will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of the global security for the debt security or for maintaining, supervising or receiving any records relating to the beneficial ownership interests.

We expect that the depositary or its nominee, upon receipt of any payment of principal, premium or interest, will credit immediately Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global security as shown on the records of the depositary or its nominee. We also expect that payments by Participants to owners of beneficial interests in a global security held through the Participants will be governed

20

by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of the Participants.

If the depositary for a global security representing debt securities of a particular series is at any time unwilling or unable to continue as depositary and we do not appoint a successor depositary within 90 days, we will issue debt securities of the series in definitive form in exchange for the global security. In addition, we may at any time and in our sole discretion determine not to have the debt securities of a particular series represented by one or more global securities and, in that event, will issue debt securities of the series in definitive form in exchange for all of the global securities representing debt securities of the series.

Payment and Paying Agents

Unless we otherwise indicate in any applicable prospectus supplement, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that unless we otherwise indicate in the applicable prospectus supplement, we will make interest payments by check that we will mail to the holder or by wire transfer to certain holders. Unless we otherwise indicate in any applicable prospectus supplement, we will designate the corporate trust office of the trustee as our sole paying agent for payments with respect to debt securities of each series. We will name in any applicable prospectus supplement any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

All money we pay to a paying agent or the trustee for the payment of the principal of or any premium or interest on any debt securities that remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the debt security thereafter may look only to us for payment thereof.

Governing Law

The indenture and the debt securities will be governed by and construed in accordance with the internal laws of the State of New York, except to the extent that the Trust Indenture Act is applicable.

21

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of shares of our common stock or preferred stock or of debt securities in one or more series. We may issue warrants independently or together with other securities, and the warrants may be attached to or separate from any offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and the investors or a warrant agent. The following summary of material provisions of the warrants and warrant agreements is subject to, and qualified in its entirety by reference to, all the provisions of the warrant agreement and warrant certificate applicable to a particular series of warrants. The terms of any warrants offered under a prospectus supplement may differ from the terms described below. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the complete warrant agreements and warrant certificates that contain the terms of the warrants.

General

Any applicable prospectus supplement will describe the specific terms of any warrants that we issue or offer, including:

• the title of the warrants;

• the aggregate number of warrants;

• the price or prices at which the warrants will be issued;

• the currencies in which the price or prices of the warrants may be payable;

• the designation, amount and terms of our capital stock or debt securities purchasable upon exercise of the warrants;

• the designation and terms of our other securities, if any, that may be issued in connection with the warrants, and the number of warrants issued with each corresponding security;

22

Exercise of Warrants

Each warrant will entitle the holder to purchase for cash the principal amount of common stock, preferred stock or debt securities at the applicable exercise price set forth in, or determined as described in, any applicable prospectus supplement. Warrants may be exercised at any time up to the close of business on the expiration date set forth in any applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Warrants may be exercised by delivering to the corporation trust office of the warrant agent or any other officer indicated in the applicable prospectus supplement (a) the warrant certificate properly completed and duly executed and (b) payment of the amount due upon exercise. As soon as practicable following exercise, we will forward the common stock, preferred stock or debt securities purchasable upon exercise. If less than all of the warrants represented by a warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants if the expiration date of the warrants has not occurred. If we so indicate in any applicable prospectus supplement, holders of the warrants may surrender securities as all or part of the exercise price for warrants.

Governing Law

Unless we provide otherwise in any applicable prospectus supplement, the warrants and warrant agreements, and any claim, controversy or dispute arising under or related to the warrants or warrant agreements, will be governed by and construed in accordance with the laws of the State of New York.

Enforceability of Rights by Holders of Warrants

Each warrant agent, if any, will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as warrant agent for more than one issue of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of the related warrant agent or the holder of any other warrant, enforce by appropriate legal action its right to exercise, and receive the securities purchasable upon exercise of, its warrants.

Outstanding Warrants

As of December 31, 2018, there were no warrants to purchase shares of our common stock outstanding.

The following description, together with the additional information we may include in any applicable prospectus supplement, summarizes the material terms and provisions of the units that we may offer under this prospectus. While the terms we have summarized below will apply generally to any units that we may offer under this prospectus, we will describe the particular terms of any series of units in more detail in any applicable prospectus supplement and any related free writing prospectus. The terms of any units offered under an applicable prospectus supplement may differ from the terms described below. However, no prospectus supplement will fundamentally change the terms that are set forth in this prospectus or offer a security that is not registered and described in this prospectus at the time of its effectiveness.

We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of unit agreement that describes the terms of the series of units we are offering, and any supplemental agreements, before the issuance of the related series of units. The following summaries of material terms and provisions of the units are subject to, and qualified in their entirety by reference to, all the provisions of the unit agreement and any supplemental agreements applicable to a particular series of units. We urge you to read the applicable prospectus supplements related to the particular series of units that we sell under this prospectus, as well as the complete unit agreement and any supplemental agreements that contain the terms of the units.

General

We may issue units comprised of one or more debt securities, common stock, preferred stock, warrants and/or rights in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

We will describe in any applicable prospectus supplement the terms of the series of units, including:

• the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

• any provisions of the governing unit agreement that differ from those described below; and

• any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units.

The provisions described in this section, as well as those described under “Description of Capital Stock,” “Description of Debt Securities,” “Description of Warrants,” and “Description of Rights” will apply to each unit and to any common stock, preferred stock, debt security, warrant or right included in each unit, respectively.

Issuance in Series

We may issue units in the amounts and in numerous distinct series as we determine.

Enforceability of Rights by Holders of Units

Each unit agent will act solely as our agent under the applicable unit agreement and will not assume any obligation or relationship of agency or trust with any holder of any unit. A single bank or trust company may act as unit agent for more than one series of units. A unit agent will have no duty or responsibility in case of any default by us under the applicable unit agreement or unit, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a unit may, without the consent of the related unit agent or the holder of any other unit, enforce by appropriate legal action its rights as holder under any security included in the unit.

Title

24

We, the unit agent and any of their agents may treat the registered holder of any unit certificate as an absolute owner of the units evidenced by that certificate for any purposes and as the person entitled to exercise the rights attaching to the units, despite any notice to the contrary.

25

DESCRIPTION OF RIGHTS

We may issue rights to purchase shares of our common stock, preferred stock, or warrants in one or more series. Rights may be issued independently or together with any other offered security and may or may not be transferable by the person purchasing or receiving the subscription rights. In connection with any rights offering to our stockholders, we may enter into a standby underwriting arrangement with one or more underwriters pursuant to which the underwriters will purchase any of the offered securities remaining unsubscribed after the expiration of the rights offering. In connection with a rights offering to our stockholders, we will distribute certificates evidencing the rights and an applicable prospectus supplement to our stockholders on the record date that we set for receiving rights in the rights offering.

An applicable prospectus supplement will describe the following terms of rights in respect of which this prospectus is being delivered:

• the title of the rights;

• the securities for which the rights are exercisable;

• the exercise price for the rights;

• the currencies in which the price or prices of the rights may be payable;

• the date of determining the security holders entitled to the rights distribution;

• the number of the rights issued to each security holder;

• the extent to which the rights are transferable;

• if applicable, a discussion of the material United States federal income tax considerations applicable to the issuance or exercise of the rights;

• the date on which the right to exercise the rights shall commence, and the date on which the rights shall expire (subject to any extension);

• the conditions to completion of the rights offering;

• any provisions for changes to or adjustments in the exercise price or number of securities issuable upon exercise of the rights;

• the extent to which the rights include an over-subscription privilege with respect to unsubscribed securities;

• if applicable, the material terms of any standby underwriting or other purchase arrangement that we may enter into in connection with the rights offering; and

• any other terms of the rights, including terms, procedures and limitations relating to the exchange and exercise of the rights.

Each right will entitle the holder to purchase for cash the amount of securities, at the exercise price. Rights may be exercised at any time up to the close of business on the expiration date of the rights. After the close of business on the expiration date, all unexercised rights will become void. The manner in which rights may be exercised will be described in any applicable prospectus supplement. Upon receipt of payment and the proper completion and due execution of the rights certificate at the designated office of the rights agent or any other office indicated in any applicable prospectus supplement, we or the transfer agent will forward, as soon as practicable, the securities purchased through upon the exercise of the rights. We may determine to offer any unsubscribed offered securities directly to persons other than stockholders, to or through agents, underwriters or dealers or through a combination of the methods, including pursuant to standby underwriting arrangements, as set forth in any applicable prospectus supplement.

SELLING STOCKHOLDERS

This prospectus relates to the sale or other disposition of up to an aggregate of 15,700,376 shares of our common stock previously issued to the selling stockholders. As described above under “The Company—Controlled Company”, we are presently a “controlled company” under the Nasdaq Marketplace Rules as a result of the ownership by one of the selling stockholders, ALPHAEON, of a majority of our shares.

The table below sets forth, to our knowledge, information as of the date of this prospectus for the selling stockholders and other information regarding the beneficial ownership of the shares of common stock held by the selling stockholders. The second column lists the number of shares and percentage of common stock beneficially owned by the selling stockholders as of April 9, 2019. The third column lists the maximum number of shares of common stock that may be sold or otherwise disposed of by the selling stockholders pursuant to the registration statement of which this prospectus forms a part. The fourth column lists the number of shares and percentage of common stock beneficially owned by the selling stockholders upon completion of the offering contemplated hereby, assuming the sale of all shares of common stock that may be sold or otherwise disposed of by the selling stockholders pursuant to the registration statement of which this prospectus forms a part. Notwithstanding, the selling stockholders may sell or otherwise dispose of some, all or none of their shares. Because ALPHAEON is our controlling stockholder, it will be deemed to be an “underwriter” within the meaning of the Securities Act, with respect to any common stock offered by it pursuant to this prospectus, and any such offering would be deemed to be a primary offering by us.

Pursuant to the rules and regulations of the SEC, beneficial ownership includes any shares of common stock as to which a selling stockholder has sole or shared voting power or investment power and any shares of common stock that the selling stockholder has the right to acquire within 60 days of April 9, 2019. The percent of beneficial ownership for each selling stockholder is based on 27,285,806 shares of our stock outstanding as of April 9, 2019. The selling stockholders have contractual rights to require us to file the registration statement of which this prospectus is a part, as described under “Description of Capital Stock-Registration Rights.”

The shares of common stock being covered hereby may be sold or otherwise disposed of from time to time during the period the registration statement of which this prospectus is a part remains effective, by or for the account of the selling stockholders. After the date of effectiveness, the selling stockholders may have sold or transferred, in transactions covered by this prospectus or in transactions exempt from the registration requirements of the Securities Act, some or all of their common stock. See the section entitled “Plan of Distribution” elsewhere in this prospectus.

Information about the selling stockholders may change over time. Any changed information will be set forth in an amendment to the registration statement or supplement to this prospectus, to the extent required by law.

PLAN OF DISTRIBUTION

We or the selling stockholders may sell the securities offered by this prospectus in any one or more of the following ways from time to time:

• through agents;

• to or through underwriters;

• to or through brokers or dealers;

• directly to investors, including through a specific bidding, auction or other process;

• directly to agents;

• through a combination of any such methods of sale; or

• by any other method permitted pursuant to applicable law.

The distribution of securities may be effected from time to time in one or more transactions, including block transactions and transactions on the Nasdaq Global Market or any other organized market where the shares may be traded. The securities may be sold at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to the prevailing market prices or at negotiated prices. The consideration may be cash or another form negotiated by the parties. Agents, underwriters or broker-dealers may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions or commissions to be received from us or the selling stockholders, or from the purchasers of the securities. Selling stockholders, dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and compensation received by them on resale of the securities may be deemed to be underwriting discounts.

Agents may from time to time solicit offers to purchase the securities. If required, any agent involved in the offer or sale of the securities will be named, and any compensation payable to the agent will be described, in the applicable prospectus supplement. Unless otherwise indicated in the prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment. Any agent selling the securities covered by this prospectus may be deemed to be an underwriter, as that term is defined in the Securities Act, of the securities.

If underwriters are used in a sale, securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale, or under delayed delivery contracts or other contractual commitments. Securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. If an underwriter or underwriters are used in the sale of securities, an underwriting agreement will be executed with the underwriter or underwriters at the time an agreement for the sale is reached. The underwriter may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for which they may act as agent. The applicable prospectus supplement will set forth the managing underwriter or underwriters, as well as any other underwriter or underwriters, with respect to a particular underwritten offering of securities, and will set forth the terms of the transactions, including compensation of the underwriters and dealers and the public offering price, if applicable. Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best efforts basis and a dealer will purchase securities as a principal, and may then resell the securities at varying prices to be determined by the dealer. The prospectus and prospectus supplement will be used by the underwriters to resell the securities.

If a dealer is used in the sale of the securities, we, the selling stockholders or an underwriter will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. To the extent required, the name of the dealer and the terms of the transactions will be set forth in the prospectus supplement.

We may directly solicit offers to purchase the securities and we or the selling stockholders may make sales of securities directly to institutional investors or others. These persons may be deemed to be underwriters within the meaning of the

29

Securities Act with respect to any resale of the securities. To the extent required, the prospectus supplement will describe the terms of any such sales, including the terms of any bidding or auction process, if used.

Agents, underwriters and dealers may be entitled under agreements which may be entered into with us or the selling stockholders to indemnification by us or the selling stockholders against specified liabilities, including liabilities incurred under the Securities Act, or to contribution by us or the selling stockholders to payments it may be required to make in respect of such liabilities. The prospectus supplement will describe the terms and conditions of such indemnification or contribution. Some of the agents, underwriters or dealers, or their affiliates may be customers of, engage in transactions with or perform services for us or our subsidiaries in the ordinary course of business.

Under the securities laws of some states, the securities offered by this prospectus may be sold in those states only through registered or licensed brokers or dealers.

We will not receive any of the proceeds from the sale by the selling stockholders of the shares of common stock. If such shares of common stock are sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting discounts or commissions or agent’s commissions. In addition to the above-mentioned methods of sale, the selling stockholders may also resell all or a portion of their securities in reliance upon Rule 144 under the Securities Act, as permitted by that rule, or Section 4(a)(1) under the Securities Act, if available, rather than under this prospectus or an applicable prospectus supplement, provided that the selling stockholders meet the criteria and conform to the requirements of those provisions.

In connection with sales of the shares of common stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the shares of common stock in the course of hedging in positions they assume. The selling stockholders may also sell shares of common stock short and if such short sale shall take place after the date that the registration statement of which this prospectus is a part is declared effective by the Commission, the selling stockholders may deliver shares of common stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge shares of common stock to broker-dealers that in turn may sell such shares, to the extent permitted by applicable law. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). Notwithstanding the foregoing, the selling stockholders have been advised that they may not use shares registered on the registration statement of which this prospectus forms a part to cover short sales of our common stock made prior to the date the registration statement, of which this prospectus forms a part, has been declared effective by the Commission.

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if any such selling stockholder defaults in the performance of its secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time pursuant to this prospectus, or an amendment or supplement thereto, under Rule 424(b)(3) or other applicable provision of the Securities Act, amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer and donate the shares of common stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

ALPHAEON will be deemed an “underwriter” and the other selling stockholders may be deemed to be “underwriters” within the meaning of Section 2(a)(11) of the Securities Act and ALPHAEON will be and the other selling stockholders may be subject to the prospectus delivery requirements of the Securities Act, which may include delivery through the facilities of the Nasdaq Global Market pursuant to Rule 153 under the Securities Act.

Any person participating in the distribution of common stock registered under the registration statement that includes this prospectus will be subject to applicable provisions of the Exchange Act and the applicable SEC rules and regulations, including, among others, Regulation M, which may limit the timing of purchases and sales of any of common stock by any such person. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of common stock to engage in market-making activities with respect to common stock. These restrictions may affect the marketability of common stock and the ability of any person or entity to engage in market-making activities with respect to common stock.

30

Certain persons participating in the offering may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act that stabilize, maintain or otherwise affect the price of the offered securities. For a description of these activities, see the information under the heading “Underwriting” in the applicable prospectus supplement.

We may engage in at-the-market offerings into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act. In addition, we may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be named in the applicable prospectus supplement (or a post-effective amendment). In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus and an applicable prospectus supplement. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

The specific terms of any lock-up provisions in respect of any given offering will be described in the applicable prospectus supplement.

The underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business for which they receive compensation.
