The President of the American Academy of Dermatology (AAD) recently commented on the concerns regarding sunblockers that contain nanoparticles, stating that the particles in them "have a long history of safe use in sunscreens and offer good options for broad-spectrum UV protection". He also stated that the US Food and Drug Administration's (FDA) sunscreen regulations, announced on the 14 June 2011 and reported on by the NIA, "would help Americans reduce their risk for skin cancer".
Comments attributed to the AAD's President highlight his support for nanotechnology in sunblockers, stating that "healthy, undamaged skin ... is an effective barrier to preventing the entry of nanoparticles into the deeper levels" of the body. Whilst he acknowledged that "widespread use of nanotechnology in medicine is currently under evaluation", he commented that "one of the main benefits of nanoparticles in sunscreens is that the small molecules can provide more protection and more even coverage on the skin's surface than larger particles".
Furthermore he revealed his approval for the FDA's sunscreen regulations, as he hopes this will encourage their use - after all, "scientific evidence supports the benefits of sunscreen usage to minimise short- and long-term damage to the skin from UV radiation and outweighs any unproven claims of toxicity or human health hazard".
