What Is Red Light Therapy (RLT)?
Red light therapy (RLT) uses specific wavelengths of red and near-infrared light to deliver gentle, non-invasive support to the body. While 660nm red light works closer to the skin’s surface, 850nm near-infrared light reaches deeper into muscles and surrounding tissues—helping support circulation, relaxation, and everyday recovery.

Red light therapy uses specific wavelengths of light to support cellular function and overall well-being. By helping cells produce more ATP—the body’s primary source of cellular energy—it may support recovery and healthy tissue function.
