Abstract
The use of topically applied vitamins has become a ubiquitous part of clinical skin care. While a part of the skin's antioxidant system that assists in protecting it from oxidative damage, vitamins A, C, and E have also proven their ability to treat photoaging, acne, cutaneous inflammation, and hyperpigmentation (Burgess, 2008). Understanding these vitamins' unique mechanisms of action and how they work in concert helps the clinician select the appropriate topicals for their patients.
