A recent study by researchers at the University of California San Francisco found Dysport more effective than Botox in reducing crow's feet. Using 90 volunteers, research injected on side of each patient's face with Botox and injected the other half with Dysport and analyzed the results one month later.
"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. However, the researchers said they found no evident of Dysport being more effective than Botox at treating other facial wrinkles.
Though Botox and Dysport are both comprised of the same active ingredient, Botulinim toxin type A, Botox has been on the market for a decade longer than its competitor, which was approved by the FDA in 2009. Thus, while Dysport may prove more efficient than Botox in the treatment of some problems, more years on the market and more studies are needed before either could be declared the superior drug.
With Dysport, moderate to severe wrinkles are temporarily reduced in appearance by blocking nerve impulses to muscles where the wrinkles show.
