I am getting VASER lipo in the coming weeks. I have a few stretch marks that I recently got from putting on 10 more pounds than usual in the winter months. I have been losing weight in prep for the surgery and have lost 25 pounds so far. My doctor said that I might have some loose skin after the surgery. Will doing more core/ab exercise and more weight loss increase my chance of the skin to retract after surgery? Or is there any advice to help me out? Thanks!
