Christa Biegler, RD

The fat soluble vitamins A, D, and E all play a role in the physiology of skin health. Topical vitamin A is most known for acne and aging, whereas vitamin D deficiency is well recognized in eczema and psoriasis. Antioxidant vitamin E boasts only introductory research, but early results appear promising. Skin is a unique organ when considering interventions as treatments can be used both topically and internally. This article pulls together the latest research on vitamins A, D, and E to help integrative practitioners looking to use oral or topical forms of these vitamins to help with various skin conditions.
