The Skin Smoothing Exfoliator is Step One of the Proactiv+ 3-Step System. This 4-in-1 daily face wash is a deep cleanser; a medicated treatment for killing acne-causing bacteria; a glycolic-acid toner; and a mild exfoliator for renewing and smoothing the skin’s surface. Glycolic acid works together with tiny exfoliating beads to gently lift away layers of dead skin cells to unclog pores; exfoliation is a special kind of deep cleansing that accelerates the removal of excess oil, makeup and other pore-clogging impurities. After cleansing, you’ll immediately notice a brighter, smoother, healthier-looking complexion. Step One also contains 2.5% benzoyl peroxide, an exclusive micro-crystal form of prescription-quality acne medicine designed to quickly kill acne-causing bacteria. Unlike some ordinary facial cleansers that can leave skin feeling dry and stripped, the Skin Smoothing Exfoliator contains a moisturizing complex designed to leave skin feeling soft, supple and hydrated. It prepares your pores for the acne-fighting power of Step Two, the Pore Targeting Treatment.
