Ingredient compatibility
Benzoyl Peroxide + Retinol: Are They Compatible?
CautionInformation from the FDA label and published sources. Not medical advice.
Why
Benzoyl peroxide can oxidize and deactivate retinol molecules on contact. It's also very drying — combining them same-time can cause severe irritation and negate the retinol's efficacy.
Usage guidance
Use at different times — BPO in the morning, retinol at night. Or alternate days. Adapalene (Differin) is stable with BPO; retinol is not.
