J Plasma is a skin tightening device, while Smart Lipo is a laser device used to target and melt stubborn areas of fat, but lacks skin tightening. Keep in mind, a combination approach is needed. With non-surgical treatments, skin tightening can be done with a combination of vanquish, venus legacy, exilis, celllutone/Zwave. For best results for skin tightening and fat removal, I recommend a hi definition procedure like a VASER liposuction, which can be performed at the same time as a tummy tuck and/or skin removal, if you're a candidate. I use VASER HI DEF with ThermRF and fat grafting to get the most fat removal, skin tightening, contour and definition. This combination will give you the most toned result. I recommend getting a formal evaluation with a hi definition physique expert. Best, Dr. Emer
