Abstract

The formal aesthetic introduction of botulinum toxin (i.e., neurotoxins) more than a decade ago has revolutionized the nonsurgical aesthetic market and transformed society's view of facial rejuvenation. Understanding the similarities and differences between U.S. commercially available neurotoxins, their characteristics and composition, where they are effective, their mechanism of action, and how to safely administer them will enable the aesthetic provider to successfully utilize this powerful tool and ultimately deliver optimal facial rejuvenation outcomes. An update on neurotoxins on the horizon is also provided. Please note that this article discusses neurotoxin use in treatment areas that are considered “off label” by the Food and Drug Administration.
