Could someone look to see if chin/ neck lipo would allow me to achieve my goal? (Photo)

Hi everyone! I'm very interested in getting chin/ neck lipo. I've included some photos to try to help determine if this would be the best possible procedure to achieve a more defined jaw line and slimmer neck. While I do understand I would benefit from weight loss and am in the process of it, 3 years ago I was 55 lbs lighter. I still felt as tho I had the same issue, obviously not as baldy, but I still found myself insecure and very unsatisfied with this area even when I was 150 lbs.
