A-Derma

A-Derma is a French dermo-cosmetic skincare brand built around a single trademarked active ingredient: Rhealba oat, a white spring oat cultivated for the brand in southwestern France. It belongs to Laboratoires Pierre Fabre, where it sits within the Pierre Fabre Dermo-Cosmétique division alongside sister brands such as Avène, Ducray and Klorane [7]. The brand specialises in products for fragile and sensitive skin, sold chiefly through pharmacies and recommended by dermatologists and paediatricians.

The brand dates its origins to 1982 [5], when its first product — a soap-free dermatological cleansing bar made with oat milk — was sold in French pharmacies.

The brand traces its scientific roots to Pierre Fabre, a pharmacist from Castres with an interest in botany, who began researching the dermatological properties of oat in the 1970s [10]. Pierre Fabre's company developed this line of research over the following years, and A-Derma was launched as a dedicated brand in 1982 by Pierre Fabre Dermo-Cosmétique. Its brand page names Pierre Fabre, "pharmacist from Castres, passionate about botany," as the figure behind the founding research [2].

The name reflects that origin: "A" for avoine, the French word for oat, combined with "DERMA" for dermatological. The launch product was the Pain Dermatologique au Lait d'Avoine, a dermatological oat-milk bar that the company describes as the first syndet — a soap-free cleansing bar — sold in French pharmacies. Pierre Fabre frames the moment as the birth of what it calls plant-based dermatology.

There is some ambiguity in how the brand presents its own age. Several Pierre Fabre and A-Derma sources, including the UK brand site and the corporate portfolio page, consistently state "since 1982" [5][7]. The French brand-story page instead uses a 40-year anniversary framing, which read literally in 2026 could imply a later start around 1984 [2]. The 1982 date is the one repeated across the majority of company sources and corresponds to the brand's stated 40-year anniversary in 2022, and it is treated here as the founding year.

According to the company's account, oat research initiated by Pierre Fabre in the 1970s preceded the brand by roughly a decade before A-Derma launched in 1982. After nearly thirty years of further work, A-Derma researchers identified what they describe as the particular dermatological benefits of young Rhealba oat seedlings, harvested while their active compounds are most concentrated.

In 2018, a peer-reviewed meta-analysis examined a formulation combining Rhealba oat plantlet extract, the L-ALA–L-GLU dipeptide and hyaluronic acid — the active complex used in the brand's Epitheliale AH line — in wound healing after dermatological procedures. Drawing on data from 2,363 patients across nine countries, the study reported a global efficacy rated good or very good by doctors in 96.8% of cases, and faster complete wound closure with the tested product than with an active comparator (12.5 versus 17.6 days) [12]. The brand marked its 40th anniversary in 2022.

A-Derma is owned by Laboratoires Pierre Fabre and operates within its Pierre Fabre Dermo-Cosmétique division. Pierre Fabre describes itself as the world's second-largest dermo-cosmetics company, and lists A-Derma as one of eight expert brands in its dermo-cosmetics and personal-care portfolio, among them Eau Thermale Avène, Ducray, Klorane, René Furterer, Même Cosmetics, Darrow and Elgydium [7].

A-Derma positions itself as a specialist in care for fragile skin, summarised in its tagline "La Marque de Soins pour Peau Fragile" (the brand for fragile-skin care) and the three-word philosophy "Dermatologie, Végétale, Engagée" — dermatology, plant-based, committed. The company frames its approach as a plant-based dermatology that pairs clinical authority with a botanical narrative, describing it as a pioneering approach "committed to People and Nature" that helps fragile skin regain its balance.

The brand's stated audience spans generations, from infants and children to adults, with sensitive, atopic or irritation-prone skin. The range is described as plant-based dermatological products for sensitive skin "across the entire family," recommended by dermatologists and paediatricians in many countries. The product line addresses conditions such as eczema and atopic dermatitis, irritation, redness, acne, dryness, sun damage and post-procedural skin, reflecting a therapeutic rather than cosmetic orientation.

Every A-Derma product is built on the brand's signature ingredient, Avoine Rhealba — a white spring oat that the company says is cultivated exclusively for the brand under organic agriculture. According to the brand-story page, the oat was selected from more than 26,000 species and is the subject of five filed patents, and the company states it acts on three proteins essential to the skin [2]. The plants are harvested young, as plantlets, when their flavonoids and saponins are most concentrated. Other named actives across the range include the L-ALA–L-GLU dipeptide, hyaluronic acid and niacinamide.

The current range is organised around skin concerns rather than ingredients. Notable lines include Exomega, for atopic-prone skin; Epitheliale Ultra Repair and Epitheliale AH, for fragile and damaged skin; Dermalibour+, for irritated skin; Cytélium, Cutalgan, the Primalba baby-care line, the acne-oriented Biology range, and the Protect sun-care line. The historic launch product, the Pain Dermatologique au Lait d'Avoine, remains the brand's founding reference point.

The Rhealba oat is positioned as the centre of A-Derma's research. The brand describes a dedicated cultivation site, "Terre d'Avoine" (Oat Land), which it presents both as the source of the oat and as an "observatory of fragile skin" for advancing scientific knowledge. Editorial coverage has summarised the supporting research as some thirty years of expertise and more than fifty studies [11].

A-Derma's sustainability messaging centres on how its oat is grown. The company states that all of its seeds are cultivated exclusively under organic agriculture, and describes a short supply chain — circuit court — in the Tarn region of southwestern France [2]. It frames its cultivation around biodiversity, including bird conservation, a ban on chemical pesticides and reduced environmental impact [5]. The brand also states that its products are manufactured entirely in France.

Beyond the 2018 clinical meta-analysis, A-Derma's products have drawn third-party attention. Editorial outlets covering French pharmacy skincare have profiled the brand and singled out products such as Dermalibour+, Exomega Control and the Epitheliale AH line. A dermatologist-authored review platform assessed the Exomega Control emollient cream as a supportive product for atopic-prone skin, citing the brand's figures of 96% efficacy for dryness and 96% improvement in itching after three weeks.

A-Derma is an active brand. A-Derma remains in continuous operation today, with live multi-language websites. As of 2026 it maintains live official websites in several languages. As a Pierre Fabre Dermo-Cosmétique brand operating continuously since 1982, it is backed by one of the larger companies in the dermo-cosmetics sector. Its headquarters and manufacturing are in Lavaur, in the Tarn department of southwestern France [12].
