Every time you smile, frown, or squint, the skin around your eyes crinkles up. Eventually, as the collagen levels diminish, your skin literally stays scrunched, and deeper creases take the place of fine lines.                                                      To the Rescue : A few ingredients are essential. The first is retinol, a vitamin A derivative that rebuilds collagen levels and helps smooth fine lines. Antioxidants like green tea and vitamin C, which help skin retain colagen, are effective wrinkle reducers, too. If your skin is especially sensitive, swap vitamin A products for peptides – protiens that also stimulate collagen growth. “peptides don’t sting or cause redness the way retinols and their cousins can, but they are also less potent.
