A Hi and thank you for your question!
There are multiple brands of neuromodulators such as Botox that can be used.
Currently there are name brand Botox, Xeomin, Dysport, Jeuveau and Daxxify.
Some injectors may have preferences of products that they use in certain areas and some patients also have preferences of product. I would find an injector to have an initial consultation with.
In your consultation with your injector you can tell them your preference, if you have one from previous injections, etc. You can also ask them about which products they prefer, or what they believe may work best based upon the area and look you are desiring.
