I want to define my jawline, which procedure would work? Cost? (photos)

For a more defined jawline to strengthen your profile (and help prevent the dreaded jawline "jowl" sagging), we use injectable fillers like Revanesse Versa - a filler known to limit swelling and give subtle, soft enhancements - or Radiesse. Using a cannula to limit pain and swelling, we inject on the bone in strategic points to get more lift and shaping, resulting in a more contoured lower face and defined, structured jawline. I would suggest getting a formal evaluation with a facial sculpting expert. Best, Dr. Emer

You can do a combination of both.
Using the lipoenzymes below the chin to reduce the exess of fat in the area and get them digest through the lynphatic system.Using fillers you can define the jaw and the chin you can bring it a little bit forwad and down in order to make the face look slimmer and tighten the area.
