This Deep-Penetrating Infrared Light (DPL) is designed for individuals with arthritis or fibromyalgia or any disability which causes poor circulation or tight muscles and/or achy joints. Stimulates cellular regeneration and activates endorphins which block pain-transmitting chemicals or nerves. Can replenish skin cells and stimulate the formation of elastin, a regenerating protein, and collagen, a structural protein/connective tissue. Not intended to diagnosed, treat, curve, or prevent any disease. Consult a doctor regarding any medical condition.
