| What is Dysport? Comments? Experiences? |
Dysport is also a Botulinum Toxin type A, like botox. The difference is that they come from a different strain of the bacteria.
While anecdotal evidence cited mostly by Dysport says that "many cosmetic physicians who have used Dysport report faster action and greater longevity for Dysport when compared to Botox", there is not research studies to back this claim up. In fact, there is not a lot of research done comparing Dysport with Botox, but the trials done on patients have shown that botox has a higher patient satisfaction, lasted longer, and had less complications. Dysport has a lower molecular weight than Botox so it "difuses" more rapidly. While this diffusing might be the cause of the reported "faster action", it is also the cause of more complications, since the toxin can diffuse to unwanted muscles.
On a review of trials of Botox and Dysport (in any place of the body), there was no statistically significant difference in the magnitude of effect or duration between Botox and Dysport, except when used for cervical dystonia, where Dysport lasted longer but also was associated with adverse effects (Movement Disorders 2004; 19(Suppl.8 ): S129S136). However a more recent systematic review ( Clin Ther. 2007 Jul;29(7):1325-37) found that Botox lasted longer and had less adverse effects when used for cervical dystonia.
In the latest review (Plast Reconstr Surg. 2008 Jun;121(6):413e-422e) comparing clinical trials for wrinkles, Botox had a better safety margin, and either lasted longer or the same as Dysport.
I think one of the main problems with Dysport is that the optimum dose has not been really found yet, with results varying quite a bit, while it's a lot more established with Botox.
Having said all this, Dysport has proven to be safe. If the price difference is not too much, I would stick with Botox. And if someone's offering Dysport, I would check that they went to special training for Dysport (as opposed to just switching) because it's tricky.
I hope this helped! |
