Why Your Acne Won't Go Away:
Dermatologist Reveals the Truth
Clearer Skin Starts with the Right Information
A simple, science-backed approach to acne care
Acne is not only a teenage concern. Breakouts can continue well into adulthood, and hormonal changes, stress, and irritation can all play a role. When acne becomes persistent, it is easy to move from one product to another without giving any single routine enough time to work.
The better approach is often simpler: choose a clinically supported treatment, use it consistently, protect the skin barrier, and be patient with the process.
From prescription access to over-the-counter availability
Differin has helped change how people access retinoid-based acne care. In the United States, Differin Gel containing adapalene 0.1% was first approved as a prescription medicine in 1996. In 2016, the FDA approved that prescription-strength adapalene gel for over-the-counter use, making it available without a doctor’s prescription. At the time, it was the first over-the-counter acne product in the United States to contain a prescription-strength retinoid and the first new active ingredient approved for the OTC acne category in more than three decades.That history continued with a newer formulation. On May 22, 2026, the FDA approved Differin Epiduo Acne Gel—containing adapalene 0.1% and benzoyl peroxide 2.5%—for over-the-counter use in people aged 12 and older. The combination brings two complementary acne-fighting ingredients together in one treatment: adapalene, a retinoid that helps address clogged pores and acne-related inflammation, and benzoyl peroxide, an antimicrobial ingredient that helps kill acne-causing bacteria.
The distinction matters. Differin Gel’s adapalene-only switch occurred in 2016, while Differin Epiduo’s dual-active prescription-to-OTC switch was approved in 2026. Together, these milestones reflect a broader movement toward making dermatologist-backed acne science more accessible while preserving clear, label-based directions for appropriate use.
Milestone | What changed | Why it matters |
1996 | Differin adapalene gel was first approved as a prescription medicine in the United States. | Established adapalene as a prescription acne treatment. |
2016 | Differin Gel 0.1% adapalene received FDA approval for OTC use. | Expanded access to a prescription-strength topical retinoid without requiring a prescription. |
2026 | Differin Epiduo Acne Gel, containing adapalene 0.1% plus benzoyl peroxide 2.5%, received FDA approval for OTC use for ages 12 and older. | Made a fixed-dose retinoid-and-benzoyl-peroxide treatment available OTC. |
Meet Heather Woolery-Lloyd, MD
Dr. Heather Woolery-Lloyd is a board-certified dermatologist and board-certified lifestyle medicine physician whose work brings together clinical dermatology, skin-of-color expertise, wellness, and evidence-based education. She is the founder of DermFriends, an educational platform and newsletter focused on skincare, and serves as Director of the Skin of Color Division in the University of Miami Department of Dermatology.
With more than two decades of experience, Dr. Woolery-Lloyd has authored more than 100 peer-reviewed papers, speaks at national and international medical conferences, and contributes her expertise to conversations about healthy, vibrant skin. Her work emphasizes a holistic, practical approach: understand the biology of the skin, avoid unnecessary complexity, and create routines people can realistically follow.
In the accompanying Go To Health! interview, Dr. Woolery-Lloyd explains why adult acne is common—particularly among women, for whom hormonal factors can be important—and why stress may coincide with more frequent breakouts. She also identifies two common treatment mistakes: changing products too quickly and using too many active ingredients at once.
“It’s so important to be patient and to keep it simple, to use something consistently to see the best results.” — Dr. Heather Woolery-Lloyd, Go To Health! interview
Heather’s simple acne-care philosophy
Dr. Woolery-Lloyd recommends a straightforward routine that can be adapted to the morning or evening, depending on when a person is most likely to stay consistent. Begin with a gentle cleanser. Apply the acne treatment as directed, using only a small, pea-sized amount for the full face. Finish with a moisturizer; in the morning, use a moisturizer with sunscreen or follow with sunscreen as appropriate.For people using a retinoid-based treatment, dryness can occur. Dr. Woolery-Lloyd discusses starting less frequently—such as every other day or every third day—if the skin needs time to adjust, then gradually increasing use as tolerated. Always follow the product label, and speak with a healthcare professional if you have questions, significant irritation, or concerns about whether the treatment is appropriate for you.
The central message is not to chase overnight perfection. Some people may notice improvement quickly, but the interview emphasizes that many people need approximately 90 days of consistent use to see the best results with Differin Epiduo. A routine that is simple enough to maintain is often more useful than a complicated regimen that causes irritation or is abandoned too soon.
Three steps for a consistent routine
1. Cleanse
Use a gentle cleanser to remove dirt, oil, makeup, and sunscreen without unnecessarily stripping the skin.
2. Treat
Apply the selected Differin treatment exactly as directed on the package. For Differin Epiduo, the interview describes a once-daily routine and a pea-sized amount for the entire face. Avoid applying more than directed; more product does not necessarily mean faster results and may increase irritation.
3. Moisturize and protect
Follow with a moisturizer to support the skin barrier and help reduce the discomfort associated with dryness. During the day, include sunscreen as part of your morning routine.
Patience is part of the treatment
Acne care is a process. Switching products every few weeks can make it difficult to know what is helping, while layering multiple active ingredients can leave the skin irritated. A focused routine, realistic expectations, and regular use create a stronger foundation for progress.
If acne is severe, painful, scarring, worsening, or not improving, consult a dermatologist or other qualified healthcare professional. Over-the-counter availability improves access, but it does not replace individualized medical advice when it is needed.
