How good is the satisfaction with Shrink Universe for improving sagging jawlines?

I used to be surprised when looking at old photos of middle-aged celebrities, wondering, "How could their faces be so small back then, but so big now?" But as I've gotten a year or two older, I've come to understand why even celebrities' faces get bigger with age. It turns out their faces get bigger as their jawlines collapse and their skin sags. Lately, my face has looked much blunter and my features seem blurry compared to before, and it turns out that's all because my jawline has collapsed. I want to firmly lift my jawline to create a V-line. Can I really see the proper results with Shrink Universe? I want to treat wrinkles around my mouth along with my jawline with Shrink Universe; in this case, should I receive treatment by specific area, or would it be better to get a full body treatment? If I get a full treatment, how many shots would be appropriate? I would really appreciate it if those who have seen results with Shrink Universe could honestly share their experiences.
