Adapalene + benzoyl peroxide
What the label says
The label for Epiduo, a prescription gel that combines adapalene (a retinoid) with benzoyl peroxide, says it is indicated for acne vulgaris in people 12 and older. It lists dry skin, contact dermatitis, burning and irritation as the most common side effects, says redness, scaling, dryness and stinging may need the gel to be stopped, and tells users to avoid sunlight and sunlamps and wear sunscreen when sun exposure cannot be avoided. Mayo Clinic describes the same combination, notes it may make skin more sensitive to sun, wind and cold, and says to use it only as directed.
What this does not cover
These sources describe one prescription product that contains both ingredients at set strengths. They do not say how to layer two separate products, so we do not give a layering rule here. Ask a dermatologist or pharmacist before combining separate adapalene and benzoyl peroxide products.
A cautious way to start
Patch-test first, use sunscreen every morning, and stop if irritation continues. Cosmetic guidance, not medical advice.
