Should I get double jaw surgery? Maybe jaw implants?

You have some options. From what I see, you could benefit from a genioplasty with buccal fat removal. Your face is very round, and a genioplasty would bring your chin down, creating more of a "V" shape in your chin. This would bring more balance in your profile, while adding length and definition to your jawline. With that, buccal fat removal would reduce some of the fullness in your cheeks. Depending on that outcome, jawline lipo can further reduce some of the jowling and add more contour to the jawline. Our office provides in-person or virtual consultations if you would like to discuss options further!

The definition comes from bone contours and one can readily augment the jawline, for example to 'sharpen' up the contours without 'jaw surgery'. Concentrate on the 'cheekbone' and jawline contours for your goal
