My sister bought these for me for Christmas two years ago and I never used them. New and unopened. PRODUCT DETAILS Inspired by professional chemical peels, these intense exfoliating overnight acid peel pads refine, retexturize, and brighten skin while you sleep. A powerful level (15%) of glycolic acid and potent fruit extracts (mango, banana, yellow mombin, and Australian kakadu plum) work together with naturally moisturizing hyaluronic acid so you wake up with fresh, soft, smooth, beautifully glowing skin. You smooth it on with a new, dual-textured peel pad, and it’s especially brilliant on the face, neck, chest, and shoulders (where there’s typically the most sun damage). Use one night per week. Avoid if you have very sensitive skin. 4 peels
