Prevage Progressive Renewal Treatment is an intensive 4-week at-home face-peeling treatment formulated to provide increasingly stronger resurfacing benefits, plus powerful antioxidant protection. Hydroxy acids are naturally derived acids that gently exfoliate surface skin cells. The hydroxy acid resurfacing power increases gradually over 4 weeks to condition your skin for the stronger levels of acid at the end of the treatment. In addition to alpha hydroxy acid (AHA), a next-generation polyhydroxy acid (PHA) is also used. PHAs have larger molecules and offer gentler exfoliation when compared to AHAs, plus PHAs have other benefits, such as moisturization and skin barrier strengthening. Idebenone, the supercharged antioxidant, combines with the hydroxy acids to protect newly revealed skin cells from free-radical damage. Buffered ingredients in this treatment keep the pH level optimally low on skin to ensure continuous and maximized results. See your skin transform week after week. * Product Features * WHAT IT DOES: * Four weeks to significantly smoother, brighter, younger-looking skin * Week 1 - Helps restore radiance and clarity * Week 2 - Helps visibly diminish fine lines and pores * Week 3 - Helps visibly reduce deeper lines * Week 4 - Helps even tone so skin looks younger BRAND NEW!
