The applications of nanotechnology and nanomaterial can be found in many cosmetic products including moisturisers, hair care products, make up and sunscreen. The nanoformulations of these materials have been shown repeatedly to give much better performance than larger particles, reflecting visible light and absorbing UV with very high efficiency.
A wide range of nanostructures have been proposed as delivery mechanisms for cosmetic ingredients in moisturisers, anti-ageing creams, and other skincare products. Lipid nanoparticles are particularly effective, as they can merge with the lipid bilayer in cell membranes, facilitating the delivery of compounds which would otherwise not be able to enter the cell. They provide the additional benefit of being totally non-toxic and biocompatible.
