Submentoplasty, Liposuction, or other?

You would do well with liposuction alone, likely better with the implant as well, but you can get similar results without something permanent and rather use fillers for the chin.  You should see an expert in body contouring and facial rejuvenation for this type of procedure.  Best, Dr. Emer.

Form your photos I cant say anything about your nose but I would definitively reecommend submental liposuction and a small chin implant. You don't have a turkey neck and at your age I would not perfom any other invasive procedures in your neck. Best to you.
