The proactiv 3-step system by Drs. Rodan and Fields helps treat and prevent acne breakouts with proven acne-fighting ingredients. The renewing cleanser and repairing lotion contain benzoyl peroxide, a proven acne medicine known to kill and prevent acne bacteria. The alcohol-free revitalizing toner helps to gently remove excess oil and soften acne-prone skin with glycolic acid. If bothersome dryness or peeling occurs, reduce application use. If going outside, use a sunscreen.
