This is a great question, and it gets into the naming of different drugs in different countries. In the U.S., we have Botox, Dysport and Xeomin. The same drugs in most parts of Europe are known as Botox (or Vistabel), Dysport or Azzulare, and Xeomin or BoCotture. So what you need to know is the same product may have different names in different countries. But the drugs are the same – so Dysport = Azzulare, no matter what the label says. Depending upon who is injecting the product and their experience, someone might like Botox more; someone else might prefer Dysport or Azzulare. The biggest difference is when you use these, you need to understand that when mixing them, we have to use different dilutions of saline to mix them – which should be of no concern to you – but should be to the clinician. More Dysport units are needed than Botox units for each indication – but this does not mean there is no difference. Twenty units of Botox equal about 60 units of Dysport; the units are not interchangeable, so this is the way it is. Depending upon the injector, you can get great results with both. Find a board-certified dermatologist or plastic surgeon, and learn more about this from them.
