save your money. Body wraps just flush out water and it'll return. There is nothing that tightens the skin, nothing. The best you can do is give it time and hope your skin has enough elasticity to bounce back if not, it'll remain loose. You can try to fill loose skin with muscle but in the case of the stomach... there is only so thick you can make your abs so you either look at surgery to remove the skin, hope it bounces back which it will to some degree with time and then live with it. I've got a friend at the gym who was skinny his entire life, hit about 35 got divorced got fat for a couple years, sloppy fat, and then got his shit together again but the damage was done and his skin elasticity was crap he has loose skin on his lower abs, he's become a gym freak he was on stage competing at about 3-4% bodyfat just 2 weekends ago and even ripped he's got some loose skin that remains, and he's about 42 now, so it's not tightening up anymore, he's going to have it cut out eventually. On the flipside, I've seen guys who have been fat for years, get fit and think they have loose skin only to find they're still holding higher bf than they think and once they get to single digits it tightens up. If it's real loose skin however then your options do become limited.
