Photobiomodulation Therapy (PBMT), generally referred to "Light Therapy" is defined as the utilization of non-ionizing electromagnetic changes within cellular structures that are receptive to photons. Mitochondria is particularly receptive to this process. At the cellular level, visible red and near infrared light (NIR) energy are absorbed by mitochondria, which perform the function of producing cellular energy called "ATP." The key to this entire process is mitochondrial enzyme called cytochrome C oxidase, a chromophore, which accepts photonic energy of specific wavelengths when functioning below par.
