This bimonthly regimen has the power to revolutionize dull, unevenly textured skin that yearns for a brighter, smoother appearance in a surprisingly short time. Composition Glycolic Acid: With the smallest particles of all AHAs, glycolic acid is exceptionally potent. It works by breaking down the bonds between dead skin cells, facilitating exfoliation and exposing fresher, renewed skin layers, resulting in visibly brighter, smoother skin. Crystal Encapsulation: Using a cyclodextrin-based shell, glycolic acid crystals are encapsulated. On the skin, they gradually disintegrate, allowing the glycolic acid to penetrate in a controlled manner to reduce the possibility of irritation. Glycerin: A highly effective humectant, glycerin attracts moisture like a magnet, keeping skin hydrated, silky, and supple. Korean Clover Extract: Native to South Korea, Korean clover extract works with glycolic acid to boost the skins natural nighttime repair and hydration process. It helps maintain the skins natural barrier, resulting in a brighter, healthier, and more balanced appearance. Instructions for use Use 2 to 3 times per week. After your nighttime cleansing, apply a pea-sized amount of Sleep Glycolic to your face, neck, and décolleté, avoiding the eye area. Follow with other serums and your nighttime moisturizer. Allow it to work overnight. Always apply sunscreen the day after using Sleep Glycolic. A patch test before application is recommended. For layering: Because Sleep Glycolic is a direct acid, it should be the first step in your nighttime skincare routine. Then, apply your other serums and moisturizers.
