Vitamin E
Vitamin E is an essential fat-soluble composed of eight naturally occurring compounds. The most important and well-known biological function of vitamin E is related to its anti-oxidant function. When used topically, vitamin E can help heal acne, promote wound healing, and prevent scarring from eczema or psoriasis. Topical vitamin E moisturizes the skin from within, reduces UV induced damage, and decreases erythema (redness of the skin) after sun exposure.
