Ultherapy to full face destroyed skin structure - it's way less firm

I had ultherapy in September, and although the level of care the nurse showed me was wonderful, the lasting results of the procedure aren't good, I actually feel very upset about the quality of my skin. I think the ulthera heat destroyed the supporting layers of my face, it feels way less firm and it folds easily. I do think my double chin has been slightly tightened but I have also been doing chin/neck exercises because of the sagginess that the treatment has caused so I think that the tightening is from a combination from both the ulthera and the exercises, it's hard to tell. There's nothing that can be done to fix it, and I don't really want anyone doing anything else to my face. I take excellent care of my skin and did ultherapy because I thought I was doing something preventative but I wish I could go back in time and never do this. I also read that it's not FDA approved for full face, just neck and chin, unfortunately I had my whole face done, which also sucks.
