18 Years Old, Granny Face, Jowls?

"I suggest reaching out to an expert for a formal consultation. I like to recommend my patients start a combination of facial rejuvenation treatments.

1) Skincare with products and microneedling/PRP
2) PDT Light Therapy a few times per month with growth factors
3) Laser treatments like Clear + Brilliant regularly and others (Fraxel, Moxi, Viva, CO2, Erbium, Halo) a few times per year
4) Sculptra injections a few times per year for collagen production with fillers like Juvederm, Restylane, Belotero, Radiesse, and/or Bellafill
5) Thermage/Ultherapy for yearly skin tightening with or without PDO or cone-based Instalift threads for lifting
6) Botox every 2 to 3 months to stop movement lines and prevent lines at rest

Best, Dr. Emer."

It appears to me that you may have a bit of a pre-jowl indentation on either side of your chin.  I would not recommend fat removal, because when you are older, this loss of fat will make you look worse.  Your appearance will continue to change as you age and when you lose some of the fat in your cheeks, it will probably help with the indentations that you have.  Because of this fact, I would not recommend doing anything permanent at this time.  If you did want to do something now, I would recommend Radiesse injections to the indented areas to help give a smoother contour to your jaw/chin area.  

It is not easy to give you an educated answer without all the facts. That is important. If it is just a volume issue then fat grafting can be done and there is no scars or incisions. You could also consider a cheek implant, but a physical exam is the best way to decide. My best advice is to visit with a board certified plastic surgeon who will truly access your issues and give you an honest opinion vs the opinion you want to hear.
