Can my face look more saggy after getting Ultherapy?

I am looking into Ultherapy, but I am hesitant because I have seen reviews saying that it actually made the face look more saggy. I heard that the lifting effect doesn't appear immediately but develops over time. However, some people have mentioned that their face looked sunken a few weeks after the procedure compared to immediately afterward. I am wondering if this is a temporary phenomenon or if it is a problem caused by losing cheek fat. In particular, could Ultherapy not be suitable for someone who naturally doesn't have much facial fat? I am considering the procedure because I am concerned about my jawline and deep cheek fat. I am curious if these aspects are checked during the consultation. Has anyone received Ultherapy while having a thin face? I am also curious if you were satisfied with the results compared to before the treatment. It is hard to make a decision right away because I am worried that I might just end up looking more haggard if I go ahead with it.
