An overview of nanotechnology and how nanoparticles may someday be used in cosmetic products was offered at the 2010 annual meeting of the American Academy of Dermatology (AAD).

"Research in the area of nanotechnology has increased significantly over the years, with significant growth expected in the near future," says dermatologist Adnan Nasir, MD, PhD, FAAD, clinical assistant professor in the department of dermatology at the University of North Carolina in Chapel Hill, who presented. "The challenge is that a standard has not been set yet to evaluate the safety and efficacy of topical products that contain nanosized particles."

Products incorporating nanotechnology are being developed and manufactured at an ever-growing rate, especially among clothing manufacturers that incorporate nanomaterials into fabrics to enhance stain and wrinkle resistance, and water repellence.

However, Nasir explains that a substantial proportion of patents issued for nanotechnology-based discoveries are currently in the realm of cosmetic and consumer skin care products. In fact, the cosmetic industry leads all other industries in the number of patents for nanoparticles, which have the potential to enhance sunscreens, shampoos and conditioners, lipsticks, eye shadows, moisturizers, deodorants, after-shave products and perfumes.
