DALLAS Aug. 3, 2009 The new anti-wrinkle facial filler Dysport, which could be used as an alternative to Botox, noticeably reduced frown lines between the eyes, according to users and independent reviewers in a study involving plastic surgeons at UT Southwestern Medical Center.

"Our study confirmed that Dysport (abobotulinumtoxinA) is a safe and effective tool in fighting wrinkles," said Dr. Rod Rohrich, chairman of plastic surgery at UT Southwestern and one of the study's authors.

The Food and Drug Administration-approved study involved 816 participants with moderate to severe frown lines (called glabellar lines) at 27 centers in the U.S. The study is available online and will appear in Plastic and Reconstructive Surgery.

Study participants, who kept diaries for the first 14 days after being injected, were given the Dysport facial filler or a placebo. Surgeons injected Dysport in various levels, dependent on sex and facial mass, at five facial points. Self-assessments and assessments by independent reviewers were performed six times over a five-month follow-up period.
