A profile view would have been additionally very helpful. However, generally speaking robust HA volumzing fillers, especially when injected at the angle of the mandible and along the jawline can not only help to define and straighten the jawline and create a more youthful, less jowly jawline, but can secondarily improve areas, such as the folds near the mouth. Further improvement of the smile lines and the incipient perioral jowls via the use of a cohesive, low viscosity, malleable HA filer. In the hands of an experienced, board certified cosmetic dermatologist filler expert, the both treatments can be performed in one treatment session of about fifteen minutes with immediate results and little to no signfiicant downtime. Hope this helps and best of luck.
