Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	NOTE 1. ORGANIZATION NovaBay Pharmaceuticals, Inc. develops and sells scientifically-created and clinically-proven eyecare and skincare products. Our leading product, Avenova® Antimicrobial Lid and Lash Solution (“Avenova Spray”), is proven in laboratory testing to have broad antimicrobial properties as it removes foreign material including microorganisms and debris from the skin around the eye, including the eyelid. Avenova Spray is formulated with our proprietary, stable and pure form of hypochlorous acid and is cleared by the U.S. Food and Drug Administration (“FDA”) for sale in the United States. Avenova Spray is available direct to consumers through online distribution channels and is also often prescribed and dispensed by eyecare professionals for blepharitis and dry-eye disease. Other eyecare products offered under the Avenova eyecare brand include Novawipes by Avenova, Avenova Lubricant Eye Drops, Avenova Moist Heating Eye Compress, and the i-Chek eyelid and eyelash mirror. We also manufacture and sell our proprietary form of hypochlorous acid for the wound care market. NeutroPhase and PhaseOne are used for the cleansing and irrigation of post-surgical wounds, minor burns, and superficial abrasions. NeutroPhase and PhaseOne are gentle, non-irritating, and non-sensitizing to skin and new tissue. PhaseOne is distributed through commercial partners in the United States for professional use only, and NeutroPhase is distributed in China by Pioneer Pharma (Hong Kong) Company Ltd. On November 5, 2021, (the “Acquisition Closing”), we significantly expanded our business by acquiring DERMAdoctor, LLC (“DERMAdoctor”) as our wholly-owned subsidiary (the “DERMAdoctor Acquisition”). DERMAdoctor offers over 30 dermatologist-developed products targeting common skin concerns, ranging from aging and blemishes to dry skin, perspiration and keratosis pilaris. DERMAdoctor branded products are marketed and sold through the DERMAdoctor website, well-known traditional and digital beauty retailers, and a network of international distributors. See Note 3, “Business Combination” below. The Company was incorporated under the laws of the State of California on January 19, 2000, as NovaCal Pharmaceuticals, Inc. It had no operations until July 1, 2002, on which date it acquired all of the operating assets of NovaCal Pharmaceuticals, LLC, a California limited liability company. In February 2007, it changed its name from NovaCal Pharmaceuticals, Inc. to NovaBay Pharmaceuticals, Inc. In June 2010, the Company changed the state in which it was incorporated (the “Reincorporation”) and is now incorporated under the laws of the State of Delaware. All references to “the Company” herein refer to the California corporation prior to the date of the Reincorporation and to the Delaware corporation on and after the date of the Reincorporation. The Company is managed as two reportable segments: (1) Optical & Wound Care and (2) Skin Care. *Liquidity* Based primarily on the funds available on September 30, 2022, the Company believes that the Company’s existing cash and cash equivalents and cash flows generated from product sales will be sufficient to fund its existing operations and meet its planned operating expenses into at least the second quarter of 2023. The Company has sustained operating losses for the majority of its corporate history and expects that its 2022 expenses will exceed its 2022 revenues, as the Company continues to invest in both its Avenova and DERMAdoctor commercialization efforts. Additionally, the Company expects to continue incurring operating losses and negative cash flows until revenues reach a level sufficient to support ongoing growth and operations. Accordingly, the Company has determined that its planned operations raise substantial doubt about its ability to continue as a going concern. Additionally, changing circumstances may cause the Company to expend cash significantly faster than currently anticipated, and the Company may need to spend more cash than currently expected because of circumstances beyond its control that impact the broader economy such as periods of inflation, supply chain issues, the continuation of the COVID-19 pandemic and international conflicts (e.g., the conflict between Russia and Ukraine). The Company’s long-term liquidity needs will be largely determined by the success of commercialization efforts. To address the Company’s current liquidity and capital needs, the Company has and continues to evaluate different plans and strategic transactions to fund operations, including: (1) raising additional capital through debt and equity financings or from other sources; (2) reducing spending on operations, including reducing spending on one or more of its sales and marketing programs or restructuring operations to change its overhead structure; (3) out-licensing rights to certain of its products or product candidates, pursuant to which the Company would receive cash milestones or an upfront fee; and/or (4) entering into license agreements to sell new products. The Company may issue securities, including common stock and warrants through additional private placement transactions or registered public offerings, which may require the filing of a Form S-1 or Form S-3 registration statement with the Securities and Exchange Commission (“SEC”). The accompanying unaudited financial statements have been prepared assuming the Company will continue to operate as a going concern, which contemplates the realization of assets and the settlement of liabilities in the normal course of business. These unaudited condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts of liabilities that may result from uncertainty related to its ability to continue as a going concern.
