Preliminary findings show laser liposuction is effective, and patients experience approximately 50 percent greater postprocedure skin tightening than in traditional liposuction as of 2015, states WebMD. Laser liposuction uses a laser to melt the patient's body fat before removing it. The Food and Drug Administration approved the procedure in 2006.
During liposuction, the doctor injects liquid into the fat to numb and shrink area blood vessels, makes a tiny incision, and vacuums out the fat, notes WebMD. Traditional liposuction removes the fat in a solid form; laser liposuction melts it first. The laser dries the blood vessels, making it possible to remove more fat and lose less blood than in traditional liposuction. Safety concerns include pain from tissue burns and scarring from improperly using the high-heat lasers.
