I finished losing weight (even though I still have a few remaining stubborn pockets) a year ago, I had loose skin and it still hasn't tightened up, people told me since I'm 17 it should tighten up but I don't think it has, I have love handles/loose skin on my stomach, and around my man boobs, Also between my stomach and chest I have this loose skin. WIll it tighten up or is surgery the only solution?
