Can Ultherapy glow treatments around the mouth cause fat loss?

I started to notice fine lines around my mouth at 41 years of age. I decided to have an ultherapy glow treatment around my mouth when I went in for treatment on the lower face and neck. About four months later I went back and had another glow treatment around the mouth. Over the course of the next year I noticed that my mouth area seemed almost shrunken in with the development of way more fine lines. Could this be related to fat loss from the glow treatments? Was I over treated? Thank you
