Obagi Clenziderm M.D. Serum Gel BPO 5% (1.8 oz) Obagi CLENZIderm MD products work together to provide a clinically proven acne-control system that delivers rapid results. What sets CLENZIderm MD apart from other acne treatments? This state-of-the-art acne system is formulated with proven acne-fighting ingredients, including a breakthrough, patent-pending, penetrating formula of 5% benzoyl peroxide. Unlike other benzoyl peroxides, it penetrates the pores deeply, all the way down the follicles, where acne first forms - to stop acne where it starts. The end result: you can achieve cleaner, healthier, breakout-free skin - fast! DIRECTIONS: CLENZIderm Serum Gel: Clean skin thoroughly before applying. Pump product 1-2 times onto pad provided and apply evenly to entire face, avoiding the eyes, nose and mouth. Use AM and PM. Because excessive drying of the skin may occur, start with 1 application per day, and gradually increase to 2 times per day. If bothersome dryness or peeling occurs, reduce application to once daily or every other day. If going outside, use a sunscreen. Allow Obagi CLENZIderm MD Serum Gel to dry, then follow directions on the sunscreen labeling.
