Bocouture is a botulinum toxin A just like Botox but it is not approved for use in the U.S. at this time. My advice would be to have your injections done by a trained physician injector and to follow-up maybe 2 weeks after your injections to see how everything looks. I don't know why Botox would have done "nothing" unless it was being used on static muscles, the wrong dilution, or an inexperience injector. Botox may not be the right solution for your needs, but it should always do "something".
