[Vitamin and dermatology].

Vitamin A, B1, B2, B6, B12, biotin, nicotinic acid, panthotenic acid, vitamin C, E and K have been used for various skin disorders. The use is mostly based on the similarity of the skin manifestations seen in their deficiencies, except for the rare cases of clear deficiency like pellagra. Recent introduction of vitamin A and D analogues for psoriasis and keratinization disorders resulted in significant progress in clinical dermatology. Application of vitamin C, E and beta-carotene++ for UV-induced skin damages are being studied, and the vitamins will be more important in dermatology in the future.
