The low-energy 650nm(5mW) laser can irradiate the circulating blood in the neck artery and the mucosal tissue in the nasal cavity so that the photoelectric biological effect will generate. Photon energy is absorbed by red blood cells and converted into internal energy, then activates different enzymes and decomposes redundant fat in the bloodstream. It increases the oxygen amount in the blood, boosts metabolism and enhances the process of lipid peroxidation to reduce cholesterol in the vessels.
