Burke, Md, observes that at least three antioxidants; selenium, vitamin E and vitamin C, are proven to decrease the effect of the sun on the skin and prevent supplementary skin damage.

In the cells not treated with vitamin C, the younger cells spurred more collagen growth than the elderly cells did.
