Suntegrity's tinted sunscreen is made with clean ingredients and mineral particles that have been proven to block not only UV light, but also blue light emitted from electronic devices such as computers and cellphones. The greatest advantage of using tinted sunscreen over regular sunscreen is that it provides protection against both UV and blue light, which can cause oxidative stress on the skin and result in premature wrinkles, dark spots, and other signs of aging. By using a daily iron oxide sunscreen, you can prevent the signs of premature aging caused by exposure to both the sun and blue light.
