Antioxidant vitamins such as Vitamin A, Vitamin C and Vitamin E are very important in fighting and preventing free radical damage.  Among the several types of damage done by free radicals is the destruction of collagen and elastin. Collagen and elastin are fibers that support the skin and keeps it looking young.

Vitamin C also plays a part in the production of collagen making it essential to the function and look of the skin.  Vitamin C and E used together may help to repair sun-damaged skin.

Vitamin A has its own important role in skin health and beauty in addition to its anti-oxidant properties.  It is one of the few substances with a small enough molecular structure to penetrate the outer layers of the skin and work to repair the lower layers of the skin where collagen and elastin reside. Its primary use is as a topical solution for the treatment of severe acne and the reduction of lines and wrinkles. A topical solution that contains both Vitamin A and Vitamin C can in some cases reverse the damage done by the aging process and by sun-damage.

A little shortage of the Vitamin B complex can result in scaly and poorly textured skin. Topical preparations have been found to play an important role in the hydrating of skin cells leading to noticeably firmer and healthier looking skin.

Vitamin K has been found to relieve those awful dark circles under the eyes.

You can get Retinol (Vitamin A) or prescription retinoid, but remember only put it at night. Because it will make skin more sensitive to the sun. Lemon is the best source for the Vitamin C. And you can buy pure Vitamin E oil from any drug store.
