This powerful Vitamin C formula stays active on skin for up to 72 hours, so you don’t have to worry about it rubbing or washing off. Chock full of essential nutrients, fruit enzymes, and a chronopeptide, skin is given a radiant glow, firmness is restored, and uneven skin tones are smoothed out. Perhaps most notable is the 15 percent solution of potent antioxidant complex, l-ascorbic and ferulic acids, and Vitamin E.
