Vitamin C is an important vitamin which is needed for many facets of our daily lives. Without it, humans cannot survive. The only ways of acquiring Vitamin C is to eat foods rich in vitamin C and take vitamin C supplements as insurance. Vitamin C is very effective in reducing oxidant stress on skin, and is required to cross-link collagen fibers. Topical applications of Vitamin C will slow the aging process by minimizing that harmful oxidant stress, and improve skin health, ton, and radiance by helping stabilize skin collagen.
