Masseter muscle reduction with micro RF, is it a good idea? How permanent is it?

I been getting Botox to reduce the jaw muscle for years I love the result but it's very costly. Now I have seen a new technique that called " Messeter muscle reduction with micro RF" my question is: 1. It supooed to damage messeter muscle permanently? Or it only stay for a few years? 2. Is it safe that messeter muscle is damaged. I mean do I might be needing it when I get much older, btw. I'm already in my early 40s. Thank you in advance for the reply.
