Morpheus8 - hoping to tighten jawline, see no difference

I purchased the package of three treatments. I was hoping to tighten up my jaw line. It's been several months and I see no difference whatsoever. I actually think I look a little worse, like what little fat I had in my face is gone. I have a good practitioner and I know different settings were used. I think this wasn't the appropriate treatment for me, as it just did not deliver results that justify the cost. It is another new machine/treatment that promises a lot but just doesn't deliver.
