Both use a laser to assist with the liposuction procedure.

Smart Lipo has been around for three years and has been modified numerous times to improve the results. It uses a 1064 wavelength laser that is attracted to water and indirectly melts fat because of the heat generated. It’s great for skin tightening.

Slim Lipo is a newer technology and has a fat specific wavelength( 924) that aids in melting fat. It also results in skin tightening.

Bottom line: they both work and your result will depend more upon the skill of your surgeon than the technology used.
