[Lifiting] hit with 600 Shurink shots

The head of counseling said that if you hit 600 shots, there will be a slurping effect, so I tried it, but I'm not sure about the effect! No one knows that I've changed, and I don't know either... When I do it, I put a lot of numbing cream on, and when I go to the chin area, it just feels a bit hot, but it didn't hurt, but the nasolabial fold area really hurt like crazy It felt like electricity went through?? The conclusion is that the effect is insignificant, and the cost and pain burden seem like a bad procedure.
