Both Botox and Jeuveau are type A neuromodulators. They have the same molecular weight, same potential side effects, are injected exactly the same way and in the US studies worked equally well and lasted equally long. The European/Canadian studies actually showed Jeuveau to be 4-8% superior to Botox. I have seen it kick in sooner than Botox as well. The processing technology is different, with Botox being freeze dried and Jeuveau being vacuum dried, which might account for it’s superiority.
Jeuveau is another form of botulinum toxin type A (prabotulinumtoxinA-xvfs) that has been FDA approved for aesthetic treatment of glabella lines in the United States. It is expected to be available Spring 2019, so clinical experience with the product is limited in this country to those who conducted the trials. Basically a wait and see.
