The LLLT mask utilizes uses focused LED lights to stimulate a process called photo biomodulation. During photo biomodulation, light photons enter the tissue and penetrate the mitochondria of the cells stimulating the production of ATP. One effect is repair and regeneration of the cells from the light bio stimulation. The light also stimulates the immune system resulting in a lowering of inflammation. The low level light gives the body a way to repair itself, reduce inflammation and heal. This technology has been used in medicine for quite some time but only recently has it’s benefit been seen in dry eye and periocular inflammatory conditions.
