Is there anyone here who knows a lot about Ulthera or InMode lifting?

I feel like my facial skin is sagging, so I am looking into lifting procedures like Ulthera or InMode, but I am getting scared after seeing cases of side effects such as cheek hollowing or burns. I would greatly appreciate it if anyone could tell me if they have actually experienced side effects after receiving the procedure, or if you could advise on what I should check most importantly when choosing a clinic before the procedure to avoid accidents.

I thought I was taking care of myself, but as I get older, there's nothing I can do about it.
