What procedure would be recommended to improve the look of my jaw line?

Dear Andrea543210,
it is hard to tell for sure without an examination. Based on your photos, it looks like you would benefit from chin liposuction. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

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

Any type of superficial liposuction techniques under local anesthesia with HA fillers along jaw line in combination. Best in person consultations. Fees in the $6,000 ranges.
