This was the first published investigation demonstrating the ability of nanoparticles to deliver therapeutic payloads deep into the dermis." One exciting nanotechnology application is a topical cream containing botulinum toxin, the neurotoxin in Botox Cosmetic (Allergan) now widely used to control facial wrinkles. Two companies are currently conducting clinical trials on similar products. They use nanospheres and absorption enhancers to deliver the toxin into the skin. Early trials are showing good results without damage to the tissue or risk of systemic toxicity. While these topicals will still be drugs available only through physicians, this needleless alternative will undoubtedly appeal to many women. And, who knows, if it proves safe enough, it might someday be applied by estheticians in medical spas.
