I used Xeomin for Cervical Dystonia, the disorder it is intended to treat. I was very happy with the results. I have been using Botox and I think Xeomin lasted longer. It definitely did what it was supposed to do. It is supposed to be better for the doctors because they don't have to keep it refrigerated before use. And if they know how to inject Botox, they know how to inject Xeomin.
