SmartlLipo makes use of an Nd:YAG 1064 laser that is delivered through a flexible fiber optic. It acts directly on the fat cells by destroying the membrane and releasing fatty and oily deposits extracellularly thus making suctioning easier. The heat generated by the laser seals the blood vessels that are broken during the process making the procedure less bloody. It also stimulates contraction of the overlying skin for better tightening.
