Leading Article


Being the most popular non-surgical cosmetic procedure, botulinum neurotoxin (BoNT) injections are increasingly of interest to all cosmetic practitioners across the globe. This article serves to update readers on the new botulinum toxins that are currently in development or close to market in the USA and Canada, including daxibotulinumtoxin A, prabotulinumtoxin A, letibotulinumtoxin A, and botulinum toxin E. Despite having relatively similar characteristics and equivalent clinical efficacies, these neurotoxins manifest a multitude of unique potential advantages that will be explored in this review, including but not limited to a longer duration of action, the absence of animal-derived components or human albumin, and a rapid onset with short duration of action.
