Study compares injectables aimed at reducing wrinkles
August 7, 2011
For the past decade, Botox, which is a version of botulinum toxin type A that temporarily weakens or paralyzes muscles that cause wrinkles, has been the most popular cosmetic nonsurgical procedure.
However, a new version of the drug, called Dysport, was recently found to deliver better results in some cases.
A study conducted by scientists at the University of California San Francisco and published in the Archives of Facial Plastic Surgery compared the effectiveness of the two injectables in reducing the appearance of crow's feet, or the small wrinkles that are common around the eye area.
For the so-called "split face" study, 90 volunteers had Botox injections on one side of their face and Dysport injections on the other. After one month, 67 percent of those who received the injections said that the Dysport side of their face looked better.
"From our findings, it's clear that there's a better smoothing effect and clearing of lines around the eyes with Dysport," the study's co-author told HealthDay. "But does that also mean that Dysport is better at achieving the same thing around the mouth or forehead or neck? We really can't make that conclusion."
Botox and Dysport are both approved by the U.S. Food and Drug Administration and are not associated with any severe safety risks.
"The most important aspect of using these different botulinum toxins is not which one you get, but making sure that you are being injected by a reputable and respected physician who does a lot of these injections," A professor of facial plastic surgery at Washington University in Saint Louis, told ABC News.
