Are you really satisfied with the results of the Shurink Universe for double chin contouring?

As I get older, I can feel the elasticity in my lower face dropping significantly, and even when I lower my head just a little, an unsightly double chin forms.

I haven't gained weight, but my facial contours have become dull, making me feel like I have a grumpy expression, and it's really stressing me out. I was debating between InMode and Shurink Universe, but I became interested because I heard the Shurink Universe treatment, which uses ultrasound to tighten the skin deep inside, is really popular these days. I'm curious if the effects of Shurink Universe, which tightens and lifts a sagging jawline, are clearly noticeable! People around me also say the satisfaction rate is really high for tightening sagging skin without the side effect of hollowing out the cheeks. Approximately how many shots would be ideal? I really need to hear your experiences from those who have had it done. !
