Dysport and Botox are both type A botulinum toxins, and they work the same way in the body to reduce dynamic facial wrinkles. In the clinical studies that were done for the FDA, both Dysport and Botox had similar effectiveness and duration, as well as similar side effects. In the clinic where I work, most patients haven't found much difference between the two products. However, there is a very slight difference in the molecular structure of the two products, so theoretically there may be some individuals who respond better to one than another; the only way to know if you are one of those is to have both treatments done and see if you can tell a difference. After your next Dysport treatment, you can give Botox a try. I had been getting Botox done for the last 5 years (I'm 30 now, and get the treatments for preventing wrinkles), but I had Dysport for my last two treatments and haven't been able to see any difference at all--they are both fantastic!
