]Once the light (of a specific wavelength) penetrates skin and reaches targeted damaged tissues, it is absorbed by light sensitive elements of the cell in a process similar to photosynthesis in plants – absorbed light is converted to usable energy, which lead to reduction of inflammation, pain relief, enhanced immune response and overall, the healing time also shortens due to more efficient cellular metabolism.
Extensive laboratory studies also suggest that irradiation stimulates collagen production, reduces oxidative stress, increases endorphin and serotonin levels and alters DNA synthesis, which are supportive for regeneration of damaged neurological tissues and other soft tissue reparation.
