Kristals Cosmetics' AMBER Multi-Vitamin C Hydration Cream is no acidic vitamin C that degrades before penetrating deep layers. This cutting-edge stabilized and highly active form of vitamin C, known as ascorbyl glucoside, goes deep into facial skin cells to lighten, brighten and correct skin tone. We combine ascorbyl glucoside with sea buckthorn oil, which is loaded with antioxidant nutrient powerhouses that can treat and prevent wrinkles, reduce skin roughness, the length of facial lines and the depth of wrinkles. We also added vitamin E and powerful red algae (astaxanthin), both of which are natural antioxidants and free radical fighters that combat premature aging.
