Is All Botox Created Equal?

Digital Vision/Thinkstock(SAN FRANCISCO) -- Botox, or botulinum toxin, is a toxin made by a bacterium which paralyzes muscles.  Because of this property, it is commonly used to reduce the appearance of wrinkles.  But people may not realize that there are different types of the toxin, and a new study from the University of California, San Francisco shows that when it comes to diminishing “crow’s feet," all botox is not equally effective.
 
In the study, published in Archives of Facial Plastic Surgery, the authors compared the effectiveness of onabotulinumtoxinA (Botox Cosmetic, by Allergan Inc.) and abobotulinumtoxinA (Dysport, by Medicis Aesthetics), both FDA approved for certain cosmetic procedures, in 90 patients with crow’s feet.  Each patient received both types of botox, one on each side of the face.  The researchers found that Dysport was more effective in diminishing crow’s feet when the patients were maximally contracting the muscles -- meaning smiling.  This finding was based on both the dermatologists’ and patients’ evaluations, who favored Dysport over Botox Cosmetic 67 percent of the time.
 
The authors point out, though, that this finding can’t be extrapolated to other cosmetic procedures and other studies would be “needed to compare these two products in different muscle groups and for other indications.”
