It has highly-active Vitamin C concentrate to minimize multiple signs of aging. This revolutionary powder-to-emulsion technology delivers the highest concentration of Magnesium Ascorbyl Phosphate (MAP) directly into the skin to helps dramatically improve skin firmness and clarity. Our highly-effective form of vitamin C works with a blend of White Tea, Hyaluronic Acid, Glucosamine, Phospholipids, Algae and Yeast extracts to help stimulate collagen production, brighten skin tone, and neutralize free radicals to dramatically increase hydration, firmness and elasticity while helping to prevent the signs of aging caused by Advanced Glycation End-products (AGEs a damaged by-product of sugar/protein reactions in the skin). The Silky emulsion glides gently over skin for efficient application, especially around the delicate eye and mouth area.
