Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited interim condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial statements. In the opinion of management, the Company has made all necessary adjustments, which include normal recurring adjustments necessary for a fair statement of the Company’s unaudited condensed consolidated financial position, results of operations, cash flow and statement of stockholders' equity for the interim periods presented. Certain information and disclosures normally included in the annual audited consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. Certain prior period amounts have been reclassified to conform to current year presentation. These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on March 17, 2022. The results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results expected for the year ending December 31, 2022.
Principles of Consolidation	Principles of ConsolidationThe unaudited interim condensed consolidated financial statements include the accounts of the Company and its subsidiaries. Intercompany balances and transactions have been eliminated upon consolidation.
Use of Estimates	Use of EstimatesThe preparation of unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and reported amounts of income and expenses during the reporting periods. Significant items subject to such estimates and assumptions include research and development accruals and valuation assumptions for share based compensation. Actual results could differ from the Company’s estimates.The COVID-19 pandemic and government measures taken in response to the pandemic had a negative impact on the Company's commercial operations in 2021. Access to healthcare providers was limited, which negatively impacted sales and the Company's ability to execute its commercial strategy with respect to AMZEEQ and ZILXI prior to the sale of the assets to Journey in January 2022. In addition, the Company further assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company and the unknown future impacts of COVID-19 as of September 30, 2022 and through the issuance of the unaudited consolidated financial statements.
Restricted Cash	Restricted CashAs of September 30, 2022, the Company had restricted cash of $0.1 million. This amount represents bank guarantees for the Company's Israel branch.
Inventories	InventoriesAs of December 31, 2021 and January 12, 2022, the date the inventory was sold as part of the sale of the MST Franchise, inventories were stated at the lower of cost and net realizable value with cost determined on a first-in, first-out basis by product. The Company capitalized inventory costs associated with products following regulatory approval when future commercialization was considered probable and the future economic benefit was expected to be realized. The Company periodically reviewed its inventory levels and, if necessary, wrote down inventory that was expected to expire prior to being sold, inventory in excess of expected sales requirements and inventory that failed to meet commercial sale specifications, with a corresponding charge to cost of goods sold.
Revenue Recognition	Revenue Recognition As a result of the disposition of the MST Franchise in January 2022, the Company no longer has any revenue generating products; however, it still receives certain royalty revenues (see Note 3 Discontinued Operations). The Company accounts for its revenue transactions under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 606, Revenue from Contracts with Customers. In accordance with ASC Topic 606, the Company recognizes revenues when its customers obtain control of its product for an amount that reflects the consideration it expects to receive from its customers in exchange for that product. To determine revenue recognition for contracts that are determined to be in scope of ASC Topic 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies the performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. Once the contract is determined to be within the scope of ASC Topic 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when such performance obligation is satisfied. The Company’s customers were a limited number of national and select regional wholesalers (the “distributors”) and certain independent and specialty pharmacies (together, the “customers”). These distributors would subsequently resell the product, primarily to retail pharmacies that dispense the product to patients. Net product revenue was typically recognized when customers obtained control of the Company’s products, which occurred at a point in time, typically upon delivery of product to the customers. The Company evaluated the creditworthiness of its customers to determine whether it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur. The Company did not assess whether a contract had a significant financing component if the expectation was such that the period between the transfer of the promised goods to the customer and the receipt of payment would be less than one year. Standard credit terms did not exceed 75 days. The Company expensed incremental costs of obtaining a contract as and when incurred if the expected amortization period of the asset that would have been recognized is one year or less or the amount is immaterial. Shipping and handling costs related to the Company’s product sales were included in selling, general and administrative expenses. The Company’s net product revenues were generated through sales of AMZEEQ, which was approved by the FDA in October 2019 and was commercially launched in the United States in January 2020, and ZILXI, which was approved by the FDA in May 2020 and was commercially launched in the United States in October 2020. The Company sold the MST Franchise on January 12, 2022 and, as such, the Company no longer generates revenue from the sale of these products. Product revenue is recorded net of distribution fees, trade discounts, allowances, rebates, copay program coupons, chargebacks, estimated returns and other incentives. These reserves are classified as either reductions of accounts receivable or as current liabilities. The estimates of reserves established for variable consideration reflect current contractual and statutory requirements, known market events and trends, industry data and forecasted customer mix. The transaction price, which includes variable consideration reflecting the impact of discounts and allowances, may be subject to constraint and is included in the net product revenues only to the extent that it is probable that a significant reversal of the amount of the cumulative revenues recognized will not occur in a future period. Actual amounts may ultimately differ from these estimates. If actual results vary, estimates may be adjusted in the period such change in estimate becomes known, which could have an impact on earnings in the period of adjustment. The Company is entitled to royalty payments with respect to sales of a product developed by a customer in collaboration with the Company. Royalties are recognized as the products developed by a customer in collaboration with the Company are sold.
Collaboration agreements	Collaboration arrangementsThe Company analyzes its collaboration arrangements to assess whether they are within the scope of ASC Topic 808, Collaborative Arrangements (ASC 808), to determine whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards that are dependent on the commercial success of such activities. To the extent the arrangement is within the scope of ASC 808, the Company will assess whether aspects of the arrangement between it and their collaboration partner are within the scope of other accounting literature.
Allowance for doubtful accounts	Allowance for doubtful accountsAn allowance for doubtful accounts is maintained for potential credit losses based on the aging of trade receivables, historical bad debts experience and changes in customer payment patterns. Trade receivable balances are written off against the allowance when it is deemed probable that the receivable will not be collected. Trade receivables, net are stated net of reserves for certain sales allowances and provisions for doubtful accounts.
Fair value measurement	Fair value measurement Fair value is based on the price that would be received from the sale of an asset or that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. In order to increase consistency and comparability in fair value measurements, the guidance establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described as follows: Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs. Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data or active market data of similar or identical assets or liabilities. Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and considers counterparty credit risk in its assessment of fair value. The Company did not have any assets or liabilities which were required to be measured at fair value as of September 30, 2022 or December 31, 2021.
Net income (loss) per share	Net income (loss) per shareNet income (loss) per share, basic and diluted, is computed on the basis of the net loss from continuing operations for the period divided by the weighted average number of common shares outstanding during the period. Diluted net loss per share is based upon the weighted average number of common stock and of common stock equivalents outstanding when dilutive. Common stock equivalents include outstanding stock options and warrants which are included under the treasury share method when dilutive.
Discontinued operations	Discontinued operationsThe Company accounted for the sale of the MST Franchise in accordance with ASC 205, Discontinued Operations, and ASU No. 2014-08, Reporting of Discontinued Operations and Disclosures of Disposals of Components of an Entity. The Company followed the held-for-sale criteria as defined in ASC 360 Property, Plant and Equipment and ASC 205. ASC 205 requires that a component of an entity that has been disposed of or is classified as held for sale and has operations and cash flows that can be clearly distinguished from the rest of the entity be reported as assets held for sale and discontinued operations. In the period a component of an entity has been disposed of or classified as held for sale, the results of operations for the periods presented are reclassified into separate line items in the consolidated statements of operations. Assets and liabilities are also reclassified into separate line items on the related unaudited condensed consolidated balance sheets for the periods presented. Non-cash items presented in the statement of cash flows and related to discontinued operations are presented in Note 3 - Discontinued Operations. ASU 2014-08 requires that only a disposal of a component of an entity, or a group of components of an entity, that represents a strategic shift that has, or will have, a major effect on the reporting entity’s operations and financial results be reported in the financial statements as discontinued operations. ASU 2014-08 also provides guidance on the financial statement presentations and disclosures of discontinued operations.Due to the sale of the MST Franchise during the first quarter of 2022, in accordance with ASC 205, the Company has classified the results of the MST Franchise as discontinued operations in its unaudited condensed consolidated statements of operations and cash flows for all periods presented, see Note 3, Discontinued Operations. All disposed assets and liabilities associated with the MST Franchise were therefore classified as assets and liabilities of discontinued operations in the Company's unaudited condensed consolidated balance sheets for the periods presented. All amounts included in the notes to the unaudited condensed consolidated financial statements relate to continuing operations unless otherwise noted.
Newly issued and recently adopted accounting pronouncements	Newly issued and recently adopted accounting pronouncementsRecent Accounting Guidance Issued:In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (ASU 2016-13), which requires companies to measure credit losses of financial instruments, including customer accounts receivable, utilizing a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Subsequent to the issuance of ASU 2016-13, the FASB issued several additional ASUs to clarify implementation guidance, provide narrow-scope improvements and provide additional disclosure guidance. As a smaller reporting company, the Company will adopt ASU 2016-13 effective January 1, 2023 or at such time where it is no longer a smaller reporting company.
