Dysport vs. Botox
Until recently, Botox, made by Allergan, was the only formulation of botulinum toxin approved for the treatment of eyebrow lines and wrinkles in the United States. Dysport is a brand of botulinum toxin made by Ipsen in the United Kingdom. Dysport is a different formulation of botulinum that is of a different size and different chemical properties. The recommended amount of botulinum measured in units is different for each brand for treatment of glabellar (between the eyebrows) wrinkles. At this time, Dysport has also been FDA-approved for this indication.
Also, Dysport is a single-use vial, but a single vial of Botox can be used for different patients.
There are some studies comparing Botox to Dysport. In the October, 2006 issue of the Journal of the American Academy of Dermatology, both botulinum toxin formulations were compared against each other in a double-blind study looking at efficacy in treatment of glabellar wrinkles. The recommended amounts of each botulinum toxin were injected in a total of 62 patients. Results were significantly better for Botox over Dysport at 12 and 16 weeks. There were no significant differences in adverse effects. Given these results, it appears that for now, Botox offers a better clinical value and better efficacy over Dysport.
At TMD Medispa, we will continue to monitor clinical research related to botulinum toxin and other cosmetic procedures so that we can provide the best possible service to our patients.
