How long does the Shrink Universe last?

Since entering my 30s, I’ve been really self-conscious about my sagging facial skin—especially my double chin and the way my cheek lines are collapsing—so I’m looking into laser lifting treatments. I’m completely hooked on Shurink Universe because it is said to be less painful than older equipment and allows for meticulous treatment even on contoured areas. Since I really can't stand pain, the fact that I can receive the treatment comfortably without general anesthesia is what I like most. However, when looking into radiofrequency or ultrasound lifting, the most important factor is the duration of the results, isn't it? I’m curious about the average perceived duration of the effects after receiving around 300 or 400 shots of Shurink Universe. Does a single treatment keep my jawline taut for about six months, or is the duration shorter than expected, requiring me to visit the clinic periodically every two to three months for re-treatments? While it likely varies by individual muscle mass and skin type, I would appreciate an honest answer from those who have consistently received Shurink Universe treatments regarding whether the lifting duration is excellent in terms of cost-effectiveness!
