Botulinum Toxin Basics for Clinicians
Botulinum toxin basics for clinicians covers how cosmetic botulinum toxin injections work and what they treat. Start with the mechanism. The American Society of Plastic Surgeons states: "Injections of botulinum toxin block the nerve signals to the muscle in which it was injected." It adds: "Without a signal, the muscle is not able to contract."
Two more references cover the same subject. Read the Cleveland Clinic's page on botulinum toxin injections for one view. The American Society for Dermatologic Surgery gives another on its page about neuromodulators.
