Conquer your pain with dpl® pain relief light therapy products. Our collection of red & infrared light therapy for pain products offers all-natural treatments for muscle and nerve pain throughout the body. Originally developed by NASA astronauts to keep muscle mass and heal in space, red LED light therapy is now available as red light therapy at home. dpl® light therapy uses the power of red and infrared light to stimulate your body's cells, reduce inflammation, repair any damage, and provide relief from muscle/joint pain & stiffness, aches, arthritis, injuries, and bruising. dpl® near-infrared light therapy devices use the same technology trusted by pro athletes and physicians with no prescription needed.
