Botulinum toxin type A for the treatment of glabellar rhytides.
Injections of BTX-A improve the appearance of glabellar rhytides by relaxing the underlying musculature in a quick and relatively painless procedure that can be performed over the lunch hour and causes few adverse effects. Alone or in combination with filling agents, BTX-A has become one of the most popular cosmetic procedures performed. Cosmetic facial aesthetics is a dynamic, rapidly evolving field, however, and producing the most optimal benefits means understanding the dynamics of facial musculature and principles of BTX-A therapy and remaining abreast of the latest clinical developments.
