How old are you and were you once heavier? When you are young and lose a lot of weight, the skin will eventually tighten up over time. The older you get, the slower and less completely this happens. I'm 50 and have lost quite a bit of weight over the last several years and have more to go. Unfortunately, my skin will never be as tight as it would be if I had always been lean and I will either have to put up with loose spots and extra folds or have surgery. I'm not terribly vain so I probably won't have surgery unless the excess skin is causing some sort of problem.
If you recently lost a good amount of weight, give it a year or two to see how much the area firms up.
