When red or near-infrared light is applied to the skin and tissues, the photons are absorbed by specialized photoreceptor cells called chromophores. This stimulates cellular energy production, predominantly by enhancing mitochondrial function and ATP synthesis[2]. Specific signaling pathways are also activated which reduce inflammation and oxidative stress[3], while increasing protective antioxidants[4], tissue regeneration and growth factors[5]. This ultimately accelerates healing and restores optimal functioning on a cellular level.
