Tumescent liposuction is the technique to which all other methods are compared. It is safe and effective. First there is injection of fluid into the fat that causes blood vessels to shrink and gives pain relief which minimizes the amount of additional anesthesia required. All of the other techniques use tumescent fluid, and are followed by the suction component of the tumescent liposuction. The only difference is that laser, smart, jet, power, tickle and all of these other tools add a step in between the tumescent and the suction to melt or otherwise break up the fat. This extra step is not necessary to achieve good results, it adds risk, and is often a gimmick.
