Prescription Dysport™ is an injection used to temporarily improve the look of moderate to severe frown lines below the eyebrows in adults less than 65 years of age.
Though approved in the United States in April 2009, Dysport has a history of use in other countries since 1991 . First approved outside the U.S. for aesthetic use in 2001, Dysport has steadily gained in popularity around the world. With its approval by the U.S. Food and Drug Administration, you, too, may join others worldwide who have been treated with Dysport.
Frown lines are "dynamic" - they happen because of the way a person's face moves. Because frown lines are created by facial movements, such as frowning or squinting, they may develop even in younger adults. Dysport is used to treat moderate to severe frown lines in patients between the ages of 18 and 65.

The muscles in the treated area above and between the eyebrows contract and tighten, and can cause wrinkles. Dysport blocks the nerve signal that causes these facial muscles to contract. This ultimately results in a localized reduction of muscle activity in the treated area and temporarily stops the tightening of these muscles.
Dysport is a purified formulation that has been shown to deliver temporary improvements in moderate to severe frown lines, even with repeat treatments. So, the effect of repeat treatment with Dysport may be comparable to your first use!
With just 1 injection into each of 5 points between and over the eyebrows,

Dysport stops the signal from the nerve to the muscles, ultimately resulting in a reduction of muscle activity and temporarily preventing contraction of the muscles that cause frown lines.
The untreated facial muscles still contract normally, allowing you to freely show facial expressions, such as laughing, in untreated areas.
