Nanotechnology in cosmetic products.

Nanotechnology is a subject of extensive global interest. The ability to control matter at the nanoscale level presents a revolutionary opportunity to benefit society in numerous disciplines. Nanotechnology is currently found in cosmetic products, particularly sunscreen products containing titanium dioxide and zinc oxide. Published information in scientific journals suggests that nano-sized ingredients used in cosmetic products pose no more risk to human health than larger sized counterparts. The issue remains under investigation.
