At a glance

Mechanism of action

Botulinum toxin is a neurotoxin that irreversibly cleaves proteins required for acetylcholine vesicle fusion and release at the neuromuscular junction. This results in temporary paralysis of muscles at the injection site. Mentor Worldwide's purified formulation is designed to minimize immunogenicity while maintaining therapeutic efficacy for cosmetic and medical applications.
