Abstract
A synergistic combination of one or more antioxidants and sunscreen agents provides superior protection of the skin against the harmful effects of ultraviolet radiation. In particular embodiments, the antioxidants include lipid soluble vitamins and water soluble antioxidants in an emulsification system, such as a polyorganosiloxane emulsifier. The lipid soluble vitamin component includes Vitamins A and E, while the water soluble antioxidant component includes magnesium ascorbyl phosphate, DL panthenol, beta glucan, grape seed extract and superoxide dismutase. The sunscreen agents may include a UVA sunscreen agent selected from the group of oxybenzone, dioxybenzone, sulisobenzone, avobenzone or zinc oxide, and at least one UVB sunscreen agent, selected from the group of ethylhexyl methoxycinnamate, DEA methoxycinnamate, padimate O, ethylhexyl salicylate, homosalate, TEA salicylate, octocrylene or titanium dioxide. The antioxidants and sunscreen agents in combination provide enhanced protection from ultraviolet radiation induced skin damage.
