Which is the Best Laser to Cause Skin to Contract, Tighten?

Please I just want an honest answer. I had horrible damage to my lower lip and skin beneath after a surgeon weaved an excessive amount of fascia though my lip (the goal was to raise my chin muscle, NOT enhance my lip). It made my lip big as a cigar. Despite the fascia removal, my skin never went back to baseline. I have loose skin beneath my lower lip, worse on one side (where he put more).PLEASE, which laser best tightens skin? Everyone says "it's my laser" no matter what kind he has. Help.
