The role of nanoparticles in cosmetics and the potential harms of enhanced absorption: a review

Abstract

As an emerging technology, Nanotechnology has already been used in many fields of technology and science, e.g., medicine, electronics, and materials science. In cosmetics too, nanotechnology can play a significant role. Even though the method of producing nanoparticles is not yet very mature, they pose significant potential in additives to cosmetics. Moreover, because of their unique properties, they can largely enhance the performance of cosmetics and cosmeceuticals. Herein, the properties and mechanisms of some typical nanoparticles for cosmetics were explained. Furthermore, some potential harms of nanoparticles in cosmetics, for example, damages resulting from the chemicals carried by liposomes, were discussed. This review intends to deepen the understanding of nanoparticle applications that can improve cosmetics quality.
