Vitamins are the rejuvenating agents for the skin that takes the stress of external climate and pollution. It is wrong to presume that chemical agents like botox can do skin repair and make skin wrinkles disappear. Vitamins can reverse the harmful oxidization effect of the free radicals on the skin. Vitamin C has been proven to be effective in increasing the production of collagen bundles which decreases due to old age. The collagen bundles provide the support for the skin and make it bouncy and elastic. Without the collagens the skin becomes thin and dry. Vitamin E is another antioxidant which would work wonders on the skin.
