Laser liposuction is effective, based on research and studies that show its patients experience less bruising, more skin tightening and a faster recovery than traditional liposuction patients, according to WebMD. However, using lasers increases the risk of burns, and the procedure is more expensive than regular liposuction, as of 2015.
In laser liposuction, a surgeon melts a patient's fat with lasers before using liposuction tools to vacuum it out. The laser energy stimulates the skin cells to produce elastin and collagen in the process, and the result is smoother, tighter skin. The outcome is a special benefit for older patients, since the body's ability to produce the proteins declines with age, notes WebMD. Less bruising results from lasers congealing tiny blood vessels in the surgical area.
