I really hate my results: I got a bbl and lipo in stomach and back. (photos)

Thanks so much for reaching out. The pictures you show are from a sitting position sonit is hard to judge your results.  Sometimes after liposuction you are left with sagging skin.  If there is enough sometimes a tummy tuck is warranted.  I hope this helps :)

The best thing to do in my opinion is to speak openly and honestly about this with your surgeon. Getting the result you want may be as easy as a revision liposuction or additional fat injection. It might be more involved requiring skin excision. Hard to tell from the pictures. But if you picked a Board Certified Plastic Surgeon, chances are that they are going to do everything within reason to help you achieve your goals. 
I hope this helps. Good luck!

The skin always creases when you sit this is normal. It does not mean you have excess skin necessarily.
