The Professional Fat Reduction System uses LED lights and optional vibration to reduce body fat. Simply place the adjustable Velcro LED light belt around the target area (abdomen, arms, legs, etc.) and set the timer on the base unit. The red LED light penetrates skin and opens the pores of fat cells, allowing fatty acids to escape and burn off more easily during exercise. Use 20 minutes per treatment area, 2 to 3 times per week in addition to exercise and a healthy diet. Not for those with open wounds, pacemakers, photo sensitivity, epilepsy, cancer, kidney or liver problems, thyroid problems or women who are pregnant or nursing.
