Galderma Receives U.S. FDA Approval for Differin® Epiduo® Acne Gel Prescription-to-OTC Switch

(BUSINESS WIRE) -- Galderma (SIX: GALD), the pure-play dermatology category leader, today announced that the United States (U.S.) Food and Drug Administration (FDA) has approved Differin^® Epiduo^® Acne Gel (Adapalene 0.1% and Benzoyl Peroxide 2.5% Acne Treatment) for over-the-counter (OTC) use in ages 12 years and older, marking a significant Prescription-to-OTC transition in acne care.

This milestone represents yet another example of Galderma’s unique Integrated Dermatology strategy, demonstrating how proven innovations from its Therapeutic Dermatology portfolio can further strengthen its Dermatological Skincare offerings. The Prescription‑to‑OTC transition highlights Galderma’s scale and expertise in successfully commercializing dermatology innovations across the full spectrum of acne care.

With the approval of Differin Epiduo OTC, Galderma is bringing its proven acne science to a broader population of acne sufferers through wider access to a dermatologist-recommended, prescription-strength treatment, while further strengthening its global leadership in acne care.

Delivering continued innovation in acne prevention and care

Differin Epiduo is a topical acne treatment that combines adapalene, a third-generation retinoid originally discovered and developed by Galderma to address the stability and tolerability challenges of earlier retinoids, with benzoyl peroxide (0.1/2.5%). This adapalene molecule reflects Galderma’s long-standing leadership in retinoid science, delivering an innovation-led approach that goes beyond traditional OTC acne actives. Together, these two dermatologist-trusted ingredients address key biological drivers of acne – clearing clogged pores, killing acne-causing bacteria, and reducing acne inflammation – to help clear acne, prevent future breakouts and improve skin tone, texture, and overall appearance.^1,2

The formulation is further powered by its Simulgel™ Gel Base, which stabilizes and evenly distributes both active ingredients while maintaining benzoyl peroxide’s efficacy and improving overall tolerability. This enables a simple, one-pump, once-daily regimen – a level of ease that is critical to building consistent routines and achieving clearer skin over time.

Clinical data supporting the approval demonstrated:

• Proven efficacy across multiple randomized, controlled Phase 3 studies, with adapalene/benzoyl peroxide gel consistently outperforming adapalene alone, benzoyl peroxide alone, and vehicle gel across inflammatory, non-inflammatory, and total acne lesions, as well as Investigator Global Assessment (IGA) success rates (“clear” or “almost clear”).^3-5

• Clinically meaningful improvement in lesion counts seen as early as Week 1, with antimicrobial activity beginning on Day 1 and up to 70.3% reduction in inflammatory acne lesions at Week 12.³

• Sustained efficacy with long‑term use, maintaining ~65% total lesion reduction in a single arm study through 12 months, which supports once‑daily, ongoing acne control.⁶

• Proven efficacy across diverse patient populations, with consistent results and favorable tolerability across skin tones.

First approved as a prescription treatment, Epiduo^® (Adapalene 0.1% and Benzoyl Peroxide 2.5%) Gel has been trusted by dermatologists for more than 15 years, with millions of prescriptions written worldwide. Its global clinical legacy includes more than ten Galderma studies involving over 3,200 patients, along with extensive third-party studies, across a wide range of ages, skin tones and acne severity. With this Prescription-to-OTC switch, Galderma continues to play a defining role in shaping modern acne care, leveraging its own proprietary science to advance dermatology, and expanding access to effective treatments.

Differin Epiduo will be available over-the-counter at most major retailers, including Walmart, Ulta, Target and Amazon, beginning in the summer of 2026. With a commitment to providing effective solutions across consumers’ acne journey, the Differin portfolio also includes cleansers, treatments, and moisturizers to support and provide wholistic solutions.
