A new, intensive 4-week at-home face peeling treatment formulated to provide increasingly stronger resurfacing benefits, plus powerful antioxidant protection, to reveal smoother, brighter, younger-looking skin. Apply nightly after cleansing. Suitable for all skin types. Clinically and dermatologist tested. Gentle Peel, Radiant Reveal Hydroxy acids are naturally derived acids that gently exfoliate surface skin cells. The hydroxy acid resurfacing power increases gradually to condition your skin for the stronger levels of acid at the end of the treatment. This at -home face peeling treatment contains alpha hydroxy acid (AHA) and polyhydroxy acid (PHA), Lactic Acid and Gluconolactone, to renew and exfoliate the outermost layer of skin. Polyhydroxy acids are larger molecules that have the same resurfacing power as traditional alpha hydroxy acids, but exfoliate in a gentler way. PHAs also have other skin benefits such as moisturization and barrier strengthening. This advanced combination of AHA and PHA in PREVAGE Progressive Renewal Treatment allows for gentler resurfacing than products that are formulated with AHAs only.
