This medium strength, deep clarifying treatment refines and resurfaces by actively exfoliating the top layers of the stratum corneum, enabling it to penetrate, rid the pores of acne-causing buildup, and help fade hyperpigmentation. 6 oz. Use for all skin types, active acne, or acne-prone skin. Refines and resurfaces. Usage: After cleansing, apply a thin coat with a fan brush to face and neck. Avoid eye, nose, and mouth openings. There may experience a mild tingle and the skin will become pink. Leave on 2-4 minutes. Remove completely with a wet towel or sponge. A series of 8 to 10 treatments, performed weekly, will progressively improve skin texture, pigment, brightness and tone, and often control many types of acne. For those looking for an intensified boost, most complexions can tolerate an 8-week series twice a year. Also excellent as part of monthly maintenance facial.
