While the skin's antioxidants — the ones you get from eating antioxidant-rich foods — do a great job protecting your complexion from free radicals, a long day spent in the sun tends to deplete them. That's where topical antioxidants come in.

Independent research found that applying Vitamin C topically fights photoaging and supports skin’s natural collagen to help keep skin visibly firm and target pigment that leads to dark spots.
