Do Nanoparticles Penetrate the Skin? Sunscreens and Beyond

Engineered nanoparticles are at the forefront of the rapidly developing field of nanomedicine, especially in the fields of cancer therapy and immune-modulation. Their unique size-dependent properties makes them suitable for a wide range of biomedical applications such as cell labeling and targeting, tissue engineering, drug delivery, drug targeting and alike. When used in sunscreens, the small size serves both practically to better absorb UV, and esthetically by not leaving a white residue on the skin.

This premise, however, may play as a double-edged sword. This is because the same properties that make nano-particles potent may pose challenges to the body’s immunity. The discussion about the safety of engineered nanoparticles has become quite polarized, with activist groups emphasizing potential risks; and the cosmetics and medical industry claiming the concern is exaggerated. The existing literature on the ability of nanoparticulate material to penetrate skin is inconclusive.

This talk will review the properties of nanoparticles, potential pathways for skin penetration and recent published data on their interaction with the skin.
