This glycolic acid-powered exfoliant gets rid of whiteheads and refines an uneven complexion. Counting on apple water, which contains natural AHA and glycolic acid, the Power Liquid helps dissolve whiteheads and blackheads as well as other impurities inside the skin. Apply only at night on the cleansed and toned face using clean hands or a cotton pad. Wait until fully absorbed before proceeding with the rest of your skin regimen. Use sunscreen during the daytime.
