Botulinum Toxin to Minimize Facial Scarring

Botulinum toxin injection has been used for a variety of indications in humans, including blepharospasm and hyperfunctional facial lines. This article describes a novel formulation of botulinum toxin, which supplies immediate feedback to the injecting physician. Additionally, recent findings are described that indicate the immediate injection of botulinum toxin into the muscles underlying a wound can improve the cosmetic outcome of the facial cutaneous scar. Future applications of these findings are discussed.
