Are multiple sessions of Botox injections needed for slimming the masseter muscle before results are noticeable?

February 18, 2017
Asked By:GDennison in Columbus, OH

8 months ago I had 40 units of Botox injected into my masseter muscles (20 each side) in hopes to slim my square jawline. This was my first Botox injection and I didn't notice any results as all. I'm 19 years old and healthy. Is it possible that my muscles are fighting back and multiple sessions are needed before I see results? Or does this procedure not work on all patients?
