10 months post-op- Will this fix the look of my neck and loose skin? Should I see a different Doctor?

I am 56. I had a SMAS facelift Sept 19/22. It's been ten months and I don't like how It looks. I still have not feeling under my chin and around my ears. My Doctor would like to make a incision under my chin and try to fix the platysma bands (in his office) and then inject fat into the hollowness to make the indent under my chin disappear. I also have a lots of loose skin around my neck and jawline. Will this fix the look of my neck and loose skin? Should I see a different Doctor?
