BOTOX and Dysport are a purified protein produced by Clostridium botulinum, which reduces the activity of the muscles that cause unwanted lines and wrinkles over time. Botox® is a simple, nonsurgical, physician-administered treatment that can temporarily smooth moderate to severe frown lines, crows feet, down turned lips, and sagging neck and jowls in people from 18 to 65 years of age. It is the only treatment of its type approved by the Food and Drug Administration (FDA). Results can last up to four months and with long term repetitive use the results can last months longer.
