Please share the cost of the Shrink Universe~

As I get older, my double chin is getting worse and my jawline seems to be sagging, so I’m looking into lifting procedures. That’s when I discovered Shurink Universe, which is said to be much less painful and have a shorter treatment time than the traditional Shurink, and I’ve completely fallen for it! However, now that I’m actually trying to decide on a clinic, I’m worried because the cost difference between places for Shurink Universe is much greater than I expected. Some places offer incredibly low promotional prices, but I’m anxious that they might give fewer shots or not be as thorough. On the other hand, I hear that places with higher price points offer a personalized 1:1 design by the doctor. I’ve heard that verifying the authenticity of the tips is important and that the procedure depends heavily on the doctor's skill, so would it be okay to just go to the cheapest place? If any members have recently received 300 or 400 shots of Shurink Universe, I would really appreciate it if you could share the approximate cost and some tips on choosing an ethical clinic that doesn't over-treat in the comments!
