Together, vitamin C and vitamin E form a synergistic antioxidant combination that provides unmatched protection from photoaging. This super-antioxidant treatment contains 15% L-ascorbic acid and 1% alpha tocopherol to optimize protection against damaging UVA/UVB rays, help prevent premature signs of aging, and stimulate collagen production. New breakthrough research shows that a combination of vitamins C and E provides a fourfold level of antioxidant protection over normal, unprotected skin. More importantly, following sun exposure, C+E can prevent the formation of constituents that are associated with the formation skin cancer. C+E is not a sunscreen, however, new research demonstrates the combination can provide better protection from UV damage than the average sunscreen in real-life application. When used with a broad-spectrum sunscreen, C+E can help provide almost complete photoprotection. Beautiful Science: A combination of vitamins C and E provides better protection from UV damage than vitamin C or vitamin E alone
