Proactiv 3 Step System
New micro-crystal medicine and 24/7 Skin Care Advisor support for ActivMembers™ are just two parts of Proactiv's more powerful, more complete approach to treating acne.
Renew
This medicated Renewing Cleanser is made with new, exclusive micro-crystal benzoyl peroxide — featuring smaller, finer particles designed to quickly penetrate pores to start killing acne-causing bacteria on contact. Tiny exfoliating beads gently remove dirt, excess oil and dead skin cells to help keep pores from clogging.
Revitalize
This refreshing, alcohol-free toner helps remove impurities and excess oil so your skin looks and feels clean, soft and refreshed -- not tight and dried out. Soothing botanical agents gently balance your skin tone.
Repair
The repairing treatment is a feather-light medicated lotion that gets deep into clogged pores faster but is designed to be gentler on the skin. It's an oil-free formula that's safe for your entire face.
