Can you use benzoyl peroxide with retinol?
Yes, but keep them in separate routines. Benzoyl peroxide in the morning and retinol at night has been shown to be a well-tolerated combination.
Why
Benzoyl peroxide is a strong oxidizer, and in lab tests it broke down an oxidation-sensitive retinoid within hours when exposed to light. Whether the same happens to retinol on skin hasn't been well studied, so separating them is a sensible precaution that also spreads out the dryness both can cause. In a 12-week study, 2.5% benzoyl peroxide in the morning with retinol in the evening was well tolerated. Benzoyl peroxide is an OTC drug ingredient in the US, so its label directions come first.
How to use them
Apply benzoyl peroxide in the morning, followed by sunscreen, and retinol at night. Keep benzoyl peroxide away from hair and dyed fabrics, which it can bleach.
Benzoyl peroxide is regulated as an OTC drug in the US. The directions on the product's label come first, and Dermo doesn't recommend specific drug products.
