  • Topical compositions containing selenoamino acids for the prevention of ultraviolet radiation-induced skin damage
    Patent number: 4865840
    Abstract: Topical application of selenoamino acids, such as L-selenomethionine, leads to significantly enhanced levels of selenium in the skin, and also to enhanced levels of selenium in the plasma and liver without toxicity. These enhanced levels of selenium provide protection from ultraviolet radiation-induced skin damage, and significantly reduce the incidence of skin cancers following ultraviolet light exposure.
