SculpSure is a laser that will destroy up to 24% of the fat cells in the treatment area in a single treatment. It is recommended to have 2 treatments for optimal results. Once these fat cells are destroyed your body has to flush them out through lymphatic drainage and drinking lots of water. Once we destroy the fat cells they are permanently gone, we don't create new fat cells after our teenage years. That being said, the remaining fat cells can get larger if you aren't eating right and exercising, the same as if you had liposuction. This makes it ideal for treating targeted areas of stubborn fat such as love handles, lower abdomen "mommy pooch", etc. Venus Legacy is radio frequency that liquefies that fat within the cell so you can flush it out through your lymphatic system. With this procedure the fat cells are still left behind and can fill back up. Venus Legacy does help smooth out cellulite and tighten laxity in the skin. I offer both treatments in my office and typically use SculpSure for fat destruction and Venus for smoothing cellulite and tightening the skin. SculpSure does tighten the skin some with the treatment, but if there was laxity to begin with the patient will benefit from having a series of weekly Venus treatments (8-12 treatments) after having SculpSure to give a more complete result. Hope this helps. Best of Luck!!
