Many studies on Vitamin C have shown that Vitamin C aids skin in two important ways. The first way is the most well known; as Vitamin C is a powerful antioxidant, defending against the free radicals generated by ultraviolet radiation.

When skin is exposed to the sun, the ultraviolet radiation causes a chain reaction of free radicals on the surface of the skin. Left untreated, free radicals can destabilize the skin molecules, leading to skin damage. The physical signs of free radical damage include lines, wrinkles, redness, and age spots. Skin also seems dry and less elastic. It may also tend to sag, reflecting a breakdown in the underlying layers containing collagen and elastin.

The second skin benefit of Vitamin C is that it aids in collagen production. Collagen is one of the skin’s building blocks. Increased collagen gives skin a firmer, more toned look- and is often associated with a younger looking appearance and healthier looking skin.

In order to be beneficial to skin, Vitamin C treatments must be kept stable and in a cool, dark environment. They work best in low pH (acidic) skin conditions and in high Vitamin C concentrations (greater than 10–15%).

If your skin is lined, wrinkled, or looks damaged, Vitamin C treatments may be just the thing you need to improve the appearance and texture of your skin.
