What's the Difference Between Exilis and Lipo Laser?

Hello, I was just wondering the difference of Exilis and Lipo Laser I know that exilis will also not help reduce stubborn fat but also help with skin tightening, but Laser Lipo also helps reduce fat as well. I had a baby 6 years ago and the only problem I have right now is the little stubborn fat in my lower abdomen due to pregnancy and was wondering what is better between those two.
