Step 2: Treatment
Apply to a naked face so active ingredients are directly on the skin, which allows them to do their jobs better (a product for uneven pigmentation follows).
Use a benzoyl peroxide, salicylic acid, or glycolic acid salve nightly. Allow sensitive skin to dry for 10 minutes after washing to minimize discomfort.
