Abstract

A topical composition for the protection of skin from damage caused by ultraviolet radiation. The composition includes a direct antioxidant and a phase 2 enzyme inducer (indirect antioxidant) in cosmetic and dermopharmaceutical compositions that protects and prevents skin damage and aging caused by UV radiation. In a particular embodiment, the composition includes a broccoli extract in combination with a composition including Hibiscus flower extract, Ferula Assa Foetida root extract, pear fruit extract, and green tea leaf extract, which exhibit a synergistic effect in protecting the skin from the adverse effects of ultraviolet radiation. In another embodiment, the composition further includes Vitamin C and Vitamin E. The antioxidant compositions can be incorporated into cosmetics, pharmaceutical compositions, sunscreen products, moisturizing lotions, skin toners, and other skin care products.
