When the body temperature rises, the human body can adapt itself before being exposed to the lipo lasers. If the wavelength is between 900 and 1400 nanometers, the temperature rises. After that, to drain fat, the wavelength drops between 635 and 670 nanometers. A lymphatic system that the body naturally has will aid in the removal of waste. Once the enormous quantities of fatty acids have been expelled, fat is reduced.
