Botulinum toxin products such as Botox® and Dysport® are used cosmetically for temporary improvement in the appearance of glabellar lines (“frown lines”) and lateral canthal lines (“crow’s feet”) in adults. Essentially, these products employ a neurotoxin, botulinum toxin type A, which works by weakening or paralyzing muscles and/or blocking nerves. In addition to its cosmetic uses, botulinum toxin is also approved by the FDA for use in a variety of therapeutic applications: overactive bladder, urinary incontinence, migraine headaches, upper limb spasticity, cervical dystonia (painful contraction of neck muscles), hyperhidrosis (severe underarm sweating), blepherospasm and strabisimus.
