This injectable treatment for wrinkles is made from the same neurotoxin (botulinum toxin type A) as BOTOX®. Dysport (formally Reloxin) received the approval of the U.S. Food and Drug Administration (FDA) for use as a wrinkle treatment in the spring of 2009, like BOTOX®, this injectable was originally developed in the 1990s to treat neuromuscular disorders.
Dysport is injected directly into the muscles that cause facial wrinkles, temporarily immobilizing them. It specifically targets the glabullar muscles — the ones that form creases on your forehead when you frown.
Dysport diffuses a bit farther from the injection point than BOTOX®: one to three centimeters compared to BOTOX’s one centimeter. This means that fewer injections are needed.
Results begin to appear within one to seven days after treatment, with day three being the median. Dysport contains less protein than BOTOX®, so the body tends to break it down more slowly. The studies are mixed, however, about whether the results lasts longer than BOTOX®.
