Nanotechnology: Cosmetic and Sunscreen Safety

Many recent cosmetic or sunscreen products have nano-sized components. Nanoemulsions are transparent and have distinctive tactile and texture properties. Nanocapsules, nanosomes, niosomes or liposomes are minor vesicles consisting of traditional cosmetic materials, and are mostly used to defend lightor oxygen-sensitive cosmetic ingredients. Vesicle materials do not pierce human skin beyond the superficial layers of the stratum corneum. When compared with the skin penetration of ingredients in traditional formulations ,nano-sized formulations may enhance or reduce penetration, albeit at a limited order of magnitude.
