You should consult a certified dermatologist, plastic surgeon or facial plastic surgeon for assessment. Hopefully, it is too much filler placed incorrectly, but infection should be ruled out. If the problem is just too much filler, it may be melted with hyaluronidase and you can start over again with filler. I would start by replacing lost volume in your upper cheeks and then proceeding to the lower face areas as needed. You should also consider Botox to lift the corners of your mouth. With this approach, you would have a more youthful, natural appearance.
I agree with Dr. Schwartz. You do not need a face lift. You need your filler placed differently and you will get plenty of "lift". Everyone has a different way of placing fillers, especially when patient wants to get rid of lines in nasolabial folds and around mouth. There isn;t neccessarily a right an wrong and choice might depend on budget. I would prefer to see your lines pulled up and out by adding volume to mid face and not to fill the actual creases themselves. That will relax creases and give your face the contour that hopefully you will love. There are several choices for this and any, done well, would be good: Sculptra, Radiesse or Perlane to start.
