A therapeutic dose of light applied to injured tissue leads to a cellular response that reduces pain and inflammation and speeds up the healing process! The primary target is the cytochrome c complex which is found in the cell mitochondria. Cytochrome c is a vital component of the electron transport chain & as laser light is absorbed, cytochrome c is stimulated, leading to increased production of Adenosine Triphosphate (ATP)/energy within the cell. Nitric Oxide is also produced which improves microcirculation in the damaged tissue, delivers oxygen, vital sugars, proteins, & salts while removing wastes. WHERE THERE IS BLOOD FLOW & ENERGY THERE IS HEALING.
