Aesthetic Uses of Neuromodulators: Current Uses and Future Directions.

Abstract

The introduction of neuromodulators for aesthetic facial improvements greatly expanded the limits of nonsurgical facial rejuvenation. Although many current uses are considered "off-label," the widespread acceptance and favorable safety profile of properly used botulinum toxins have made them one of the most common aesthetic treatments available. A literature review of current facial aesthetic uses of various botulinum toxin preparations was done, and general concepts were identified. Currently, Food and Drug Administration-approved botulinum toxin preparations onabotulinumtoxinA (Botox), abobotulinumtoxinA (Dysport), and incobotulinumtoxinA (Xeomin) have similar off-label indications and clinical uses. Although not considered interchangeable, administration and clinical outcomes are not much different between the 3 commonly used botulinum products. The impact of botulinum products currently in development has yet to be determined.
