Synergism of vitamins A and E with dermatologic applications

A synergism between vitamins A and E has been demonstrated by a number of investigators, notably Stanley R. Ames, who showed that in rats on a vitamin E deficient diet, the serum vitamin A level remained low, no matter how much vitamin A was given by mouth, or even by injection, but that adding vitamin E to the diet restored the vitamin A serum level to normal. We have utilized these observations with a high degree of success where vitamin A alone had failed to control three dermatologic conditions involving a defect in keratinization, namely, keratosis follicularis (Darier's disease), pityriasis rubra pilaris, and acne vulgaris. It is possible that a number of additional dermatoses characterized by dyskeratosis or hyperkeratosis might also be benefited by this combination.
