Abstract
Abstract The invention relates to a composition and method of dissolving melanin in a composition for the purpose of photoprotection of the human epidermis from exposure to the sun's harmful rays. The composition consists of melanin, as an active ingredient, sunscreens, vitamins and emollients. These ingredients are rapid blended by ultrasound for 2-3 hours to form a mixture that enhances the sun protective factor when applied topically.
