Summary : Although still not conclusive, the studies described indicate that topically applied vitamin E can provide protection against ultraviolet radiation when applied alone or in combination with other antioxidants. The general consensus is that, although less stable than the tocopherol esters when used in cosmetic systems, the alcohol form of alpha-tocopherol is the most effective topically-applied skin protectant. Increased UV protection potentially reduces the risk of skin cancer. However, the debate continues regarding the skin’s ability to hydrolyse ester forms of alpha-tocopherol, which are used commercially because of their greater stability during processing and over time in these products. Further research is therefore needed in order to provide more definitive data on what potential benefits or possible disadvantages may be associated with use of the ester forms in these topical applications.
