Cleanse the skin thoroughly before applying medication. Cover the entire area with a thin layer one to three times daily. Because excessive drying of the skin may occur, start with one application daily, then gradually increase to two or three times daily if needed or as directed by a doctor. If bothersome dryness or peeling occurs, reduce application to once a day or every other day. If going outside use a sunscreen. Allow benzoyl peroxide gel to dry, then apply sunscreen.
