New in box. Purchased directly from SkinStore. Boasting an antioxidant blend of 15% Pure Vitamin C (L-Ascorbic Acid), 1% Vitamin E (Alpha Tocopherol) and 0.5% Ferulic Acid, the daytime serum envelops skin in a protective veil. This shields the visage from age-inducing free radicals, infrared radiation and ozone pollution, which can all contribute to visible signs of skin aging.
