Nanoscale Cosmetics "Nanoparticles can play a major role in creating more attractive cosmetic formulations." SAFETY "These are all exciting applications, provided they are proven to be safe," cautions chemist John Kulesza, president of Young Pharmaceuticals (youngfarm.com). "No matter the composition, nanoscale particles can exhibit radically different characteristics from standard versions of the same material. This is why products incorporating nanoscale particles must undergo rigorous testing to prove they are safe and effective."

Legally, cosmetic manufacturers are not required to get premarket approval for any formulation, even those containing nanomaterials. They are legally responsible for the safety of all of their products, however, and all products must be properly labeled. No cosmetic is permitted to make medical claims. The new FDA guidelines ask manufacturers to do additional testing of products with nanoscale ingredients, and they make suggestions for the most effective types of testing. Manufacturers are also encouraged to comment on the guidelines, and their feedback could lead to mandatory regulations in the future. The Nanodermatology Society issued a response to the guidelines, praising the FDA's neutral stance and the agency's ongoing mission to provide better oversight. Other organizations, such as Friends of the Earth (foe.org) and International Center for Technology Assessment (icta.org), were disappointed that the FDA did not take more stringent action. In a May 2012 news release, these organizations stated that, "existing research raises red flags, indicating that nanomaterials have the ability to enter the bloodstream through contact with the skin, ingestion and inhalation, as well as move in the natural environment once discarded." These organizations call for greater restrictions on their use. Scientists at the University of Bath in England released a study in August 2012 (Journal of Controlled Release) that may ease those fears, especially when it comes to the nanoparticles used in sunscreens. They looked at various skin samples
