Skin is a protective barrier against external environment and it plays several important physiological functions. Skin aging is done by two different processes. One is called intrinsic aging and the other is called extrinsic aging. The excess of free radicals is a positive factor for aging. They are continually produced by the body and neutralized by antioxidants. This paper aims at studying the action of antioxidant vitamins in skin aging. This literature review was carried out based on books, monographs and journals indexed in the SciElo database. The most cited Vitamins in literature, because they have antioxidant, are retinol, ascorbic acid and tocopherol. Such vitamins combat free radicals and aid in maintaining the integrity of the cells, acting positively on the prevention of skin aging. The literature indicates the importance of proper food consumption as a factor for the prevention of skin aging. However, it does not signal established and recommended doses for this purpose.
