Is the satisfaction rate for Ultherapy generally high, even for those concerned about sagging jawlines?

As I get older, I feel like my jawline is sagging before my whole face, so I am looking into lifting procedures.

Especially when taking a side profile photo, it is noticeable that the boundary between the jaw and neck has become more blurred than before.

I know that Ulthera is widely used to improve this kind of sagging, but
I am wondering if the results differ depending on whether there is a lot of facial fat or little.
