What are nanoparticles (NPs) and why are they used in cosmetics? These questions are addressed by highlighting recent developments in the field of nanotechnology that have increased the potentially skin exposure to NPs. Trends emerging from recent literature suggest that the positive benefits of engineered NPs for use in cosmetics outweigh potential toxicity concerns. This chapter begins with an overview about the nanostructures that are applied in cosmetics and why. It is followed by a discussion of the current state of understanding of the skin penetration of NPs, the methods that can study the distribution, and the risk factors induced by the nanostructures. The chapter focuses on NPs used in formulation.
