A You have very nice skin. That is good news. In my hands, you would do best with a combination of submental lipo and/or tightening (possibly facetite, thermi...) then chin augmentation. Implant, fillers, fat we have plenty of options. It is all about creating nice balance with a sharp cervico-mental angle. Hot is Hot and that is an attractive feature in everyone.
Hope this helps,
Find a surgeon you trust and be clear with your goals.
