What are treatment options for sweating excessively? Is laser treatment for facial/scalp sweating and back sweating possible?

During hotter climates or intense exercise, I sweat quite a bit on my face/scalp and my back area where my shirts can be drenched in sweat. I've done research but most of treatments seem to be focused toward underarm sweating and I want to know more specifics of facial sweating and back sweating treatments. Can laser treatment be used on face and back as well? Where else can Botox be used? I'm looking for a long term/permanent solution if possible. Thanks!
