Ultrasound fat cavitation drains fat cells, rather than destroying them like liposuction does. Fat will almost always come back, but with fat cavitation, at least it won't appear where you least expect it. For results to last longer, you'll need a good diet and plenty of regular exercise. You certainly don't need both, cavitation liposuction uses ultrasound to alter fat, laser liposuction uses laser heat (light), Microaire or standard liposuction also works, requires less time and costs more, there are no studies comparing the results of cavitation with laser liposuction.
Consult a plastic surgeon who can rent these machines as needed. Machine owners have a financial interest in selling them to you. Ultrasound and Laser Cavitation Lipo is a weight loss treatment that uses ultrasonic energy to attack fat cells while combining laser energy to penetrate fat cell membranes. This is followed by the placement of Lipo laser pads to emit laser energy that further targets fat cells.
The main difference between the two treatments is that laser liposuction treatments, which usually last several hours, heat fat cells before removing them through a cannula. Ultrasonic cavitation and laser lipo are an excellent alternative to surgical procedures such as liposuction.
