I had gastric bypass in 2003 lost aproximatily 150 lbs. had multiple plastic surgeries to remove excess skin. Last year I heard about exilis decided to try it to tighten up loose skin. To my surprise it tighten up my legs, stomach, love handles inner and outer thighs. It also got rid of some excess fat that didn't get removed with the lipo. I also had some skin tightening on my chicken neck. I truly believe it postponed a neck lift. I would recommend this to anyone who is looking to have fat removed by surgery. Overall it tighten loose skin and also removed some fat. I am so pleased with the outcome of the procedures I have had preformed.
