Alpha-H

Alpha-H is an Australian skincare company built around exfoliating acids, founded in 1995 on the Gold Coast by beauty therapist Michelle Doherty [8]. It is best known for Liquid Gold, a glycolic acid treatment that became the brand's flagship and helped popularise acid-based exfoliation in at-home routines. The company's own pages date its history to "over 30 years ago," which is consistent with the 1995 founding recorded in Doherty's later interviews [2].

Since 2019 the brand has been owned by the American private equity firm The Riverside Company, according to the trade publication Beauty Independent; Alpha-H continues to operate under its own name. Doherty died in 2020, and the company has remained active, with an operating e-commerce site and continued product launches.

Alpha-H was founded by Michelle Doherty, a beauty therapist who had struggled with chronic cystic acne through her teens and twenties. According to accounts of her career, she discovered the early Alpha-H range, saw quick results, then left her job and bought the company. She is described as an early advocate for glycolic acid in consumer skincare at a time when the ingredient was widely distrusted. "When I go back to 1995, everyone was so frightened of the word 'acid,'" she recalled [8].

The original 1995 range consisted of four products. Doherty framed the brand's purpose as bringing professional treatments into ordinary routines, saying the aim was to make active skincare normally bought from professionals "available to a larger audience for their home-care use." The company has since grown to more than 60 products.

The Riverside Company, a private equity firm, acquired Alpha-H in 2019, as reported by Beauty Independent [8]. The brand's own "behind the brand" page does not mention the acquisition or name a parent company, instead describing the business by its founding story [2]. The two accounts are not contradictory so much as differently scoped: the brand site emphasises heritage, while the trade press records the change of ownership. No sister brands are documented in the available sources.

Alpha-H positions itself around clinical-style results achieved at home, a stance it ties to its roots in professional skin clinics. "Alpha-H is known for delivering clinical results at home, because we started in clinics," the company states on its professional-channel page. Its stated approach rests on three steps — cleansing without stripping the skin, exfoliating with acids, and protecting the barrier through hydration and sun care.

The company describes its mission as blending science and nature to promote "clear, resilient and radiant skin," and markets its formulas as transparent, listing a long roster of excluded ingredients such as parabens, sulfates (SLS and SLES) and mineral oil. It also states that its products are "100% cruelty free" and that it does not test on animals [4]. The brand presents itself under the banners "Female Founded," "Australian Made," "Conscious Beauty" and "Science Backed."

Editorially, Alpha-H is grouped with the "A-beauty" trend — Australian skincare characterised by concentrated, science-led formulas. Refinery29 described it as "an Aussie cult classic" and "an Australian cosmeceutical brand" [7].

The brand's defining product is the Liquid Gold Exfoliating Treatment, a glycolic acid lotion originally designed to extend the results of in-clinic peels. It launched the brand and remains central to its identity. Other products in the range include the Multi-Peptide Revitalise Serum, a Vitamin A serum with retinol, a Vitamin B serum with niacinamide, and the High Tide Water Cream, a gel-cream with hyaluronic acid and vegan squalane.

Glycolic acid is the company's signature active, which it credits with accelerating skin renewal by loosening the bonds between dead skin cells. The wider ingredient list spans other acids such as lactic and salicylic, retinol and granactive retinoid, a stable vitamin C (ethyl ascorbic acid), niacinamide and a range of peptides. The brand attaches "clinically proven" claims to several ingredients and proprietary complexes; these are the company's own characterisations [5].

Beyond direct sale, Alpha-H runs a professional channel supplying clinics and salons through skincare distributors, offering peel-based formulations exclusive to that channel [6].

Liquid Gold has drawn repeated attention from the beauty press. Harper's Bazaar described it as having reached "cult status" with a "miracle factor," and the product was cited among the magazine's Beauty Hot 100 selections [10]. Vogue UK called it "long … a staple in every beauty editor's bathroom." By industry accounts the product has sold at a reported rate of two bottles a minute [9]. Refinery29's 2022 review reaffirmed its standing as a cult product within the A-beauty category [7].

Alpha-H's manufacturing is based on the Gold Coast, where the company says 195 solar panels supply more than 60% of the site's energy and cut emissions by roughly 67,000 kilograms a year. It states that 100% of its liquid waste is diverted to land revegetation projects through a Queensland waste partner, that roughly 30–35% of its tubes and bottles use recycled materials, and that it sources palm oil from suppliers certified under the Roundtable on Sustainable Palm Oil [3]. The available sources list no third-party ethical or sustainability certifications.

Alpha-H is an acquired but operating brand. Since the 2019 purchase by The Riverside Company, it has continued under its own name, with an active e-commerce site and ongoing product launches at the time of review in 2026. Founder Michelle Doherty died on 31 July 2020, aged 57, after a two-year illness [8]. The brand reports distribution across more than 25 countries — including Sephora, the department store Myer, prestige clinics and a number of premium airlines — and ships internationally across the Asia-Pacific region and beyond [9].
