Will Yag Laser Tighten Up Small Amount of Loose Belly Skin?

I have some loose skin on my tummy . Will the Yag laser help me with skin tightening? I have excellent diet and my weight is 120 and my height is 5'5. I exercise 3 times a week. I had lipo in order to have a buttock augmentation. That's were they did lipo to transfer the fat to my butt. When I stand up you see some sagging but not terrible. Should I try laser skin tightening, vella shape or tummy tuck?
