How it works: Like most other body sculpting procedures, Vanquish uses a radio frequency to shock fat cells by use of heat. "It's almost like sitting in front of a radiator for an hour," says Frank. "It uses those radio frequencies to heat up and melt the fat. There's [credible] science behind it, but it's not as widely used as others -- though many patients have seen results."

Who should try it: Someone who's had liposuction in the past or has recently lost weight. This procedure is also primarily used to treat the abdomen.

Pros: Vanquish takes only 45 minutes. It's painless and requires zero downtime.

Cons: This requires multiple treatments (four to six sessions) as it cannot treat all problems areas at once. Also, compared to other treatments, Vanquish's results are "subtle," says Frank.

How it works: Velashape combines the use of radio frequencies, ultrasound waves and suction to reduce fat around the stomach, hip and thigh area. Essentially, the suction brings the fat closer to the surface of the skin, where the ultrasound waves begin to heat the area. The radio frequencies then distribute that heat evenly throughout your targeted problem area to speed up the process and reduce any damage that could be done to the skin.

Who should try it: Those looking to take off an inch or two, and reduce the appearance of cellulite around the stomach, hip and thigh region.

Pros: This procedure also helps to reduce the appearance of cellulite, due to reducing the volume of fat on the treated area. There is no down time and it's virtually painless.

Cons: This treatment requires between four to six sessions to zap problem areas.
