Vitamin C

There is an increasing awareness that vitamin C has a wide variety of role in human health. New therapeutic uses are being investigated daily, among recent discoveries is that Vitamin C can play important role in the health and beauty of your skin. Vitamin C as ascorbyl form has been tested extensively and reported in journal of American Academy of Dermatology to inhibit the production of the melanin (Melanin is the pigment which give the skin it's dark color), when Vitamin C inhibit the production of the melanin, a lighter and brighter skin will reveal in just few weeks.
Vitamin C does more than that also, vitamin C is required for collagen synthesis, which declines markedly in aging skin. As we grow older, we suffer diminished micro capillary circulation within our skin, which deprives our skin cells of the supply of vitamin C it needs for youthful collagen synthesis. The topical application of vitamin C in a skin-penetrating medium can dramatically enhance the availability of vitamin C for collagen production.
Vitamin C regenerates vitamin E in the skin. An antioxidant like vitamin E can only suppress a limited number of free radicals before it runs out of electrons to donate. Vitamin C regenerates vitamin E and enables vitamin E to provide sustained antioxidant protection in the skin's elastin fibers.
Vitamin C plays a vital role in skin repair. When your skin is injured, its Vitamin C content is used up rapidly in the scavenging of free radicals, and in synthesizing collagen to speed healing.
