Laser lipolysis is a minimally invasive procedure that uses heat from fiber-optic lasers at various wavelengths to melt body fat. This is a different process than liposuction, which involves removing fat from the body using vacuum suction. The added benefit of laser lipolysis is that it spurs the production of the protein collagen, making skin more taut.
Clinical results were drawn from the laser lipolysis and liposuction procedures of more than 2,000 patients over a three-year span. Researchers found that patients overall lost significant fat bulk in different parts of the body and saw an increase in skin tightness.
