Botox have been used for neck spasms, cranial nerve disorders and eye spasms. With the recent FDA approval of Botox® for cosmetic use , the drug is used to smooth wrinkles. When injected into facial muscles botulinum toxins block nerve impulses, temporarily paralyzing muscles and smoothing wrinkles. Currently Botox® is the only form of botulinum toxin approved by the FDA for cosmetic purposes in the glabellar region, but two others, MyoblocTM and Dysport® are under FDA review for cosmetic use.
