Botox, Dysport, and Xeomin are examples of neurotoxin or Botulinum toxin A that are injected into muscles and relax the muscles. From a cosmetic standpoint, the result is either to smooth facial lines caused by the muscle creasing the skin (11’s, forehead, crows feet), decrease muscle bulk (masseters or mentalis) or to decrease the strength of muscles that cause pulling of facial structures or skin (gummy smile or neck bands). Botox has even been studied for depression with results that exceeded the expectations of researchers.
Botox has been studied and is now being used to treat many medical conditions. The list includes but is not limited to: migraines; overactive bladder; blepharospasm (eye twitching); hyperhidrosis (excess sweating); muscle contractures (torticollis, cerebral palsy; stroke).
