Best Way to Get a More Defined Jaw Line?

Very conservative liposuction and a chin implant that extends across the pre jowl area will improve this quite a bit. You should make sure the surgeon has a great deal of experience and doesn't remove too much fat.

Hi,

Liposuction of your neck and jawline along with a possible chin-pre-jowl implant should give you nice definition of your jawline.  If more is needed then consider Sculptra injections.

Good luck and be well.

You are on the right track as one or both of those options would help. From the photo it is difficult to tell whether improvement would be greater with one vs. the other or both. The final recommendation would be dependent on the pinch thickness of the neck just below the jawline to get an idea of the amount and location of any excess fat at palpation of the jaw to see if it is smaller than average.
