I'm 21 years old and insecure about my jawline and chin. I want to have a nicer side profile. How much would a procedure cost?

While PDO threads could help, you may want to try to dissolve some of the fat around your jawline, using CoolSculpting or Kybella. This should give you more definition and address the turkey neck. After that if you feel like there is some sagging, you can do a PDO thread lift. The prices vary depending on how many sessions you will need for CoolSculpting and Kybella. PDO thread lifts can range anywhere from $2500-4500 depending on your provider.

Thank you for your question and photo.  There are several non-surgical options available for your neck that can be discussed with a board certified plastic and reconstructive surgeon with extensive injection experience. For instance, Kybella injections will destroy fat cells in this area. I would consult with an experienced injector. Then, Instalift Sihouette threads would give you the jaw definition and neck lifting you are looking for. These are threads that are inserted to lift and tighten your neck, while dissolving overtime and generating your own collagen over four months. This lasts a couple years. It is not the home run of surgical lipo, but a short in-office appointment in comparison to a hospital surgery center and anesthesia.Please consult with an Oculofacial surgeon / injector in your area.Dr. Kristin Tarbet, MD, FACS
