Benzoyl peroxide and tretinoin: keep them apart

Keep them apart

Use them at different times of day, applying benzoyl peroxide in the morning and tretinoin at night, because they cancel each other out. Combining them in the same routine causes the benzoyl peroxide to oxidize and deactivate the tretinoin, which stops them from working properly. You can change your routine by using a gentler strength, or by putting more time between the two products.
