A top board certified PS did my lower face/neck lift. He said the area under my chin would be tightened; now there's a 2-3" inch scar there. My droopy profile, jowls are corrected. I'm only 3 wks out and can't see full results due to swelling in cheeks, jaw, submental area, but I do see platysma banding now. How can this be if the muscle was tightened? Are there other neck muscles that can be tightened besides the platysma? If it was a cervicoplasty, does that tighten muscle as well?
