Red light lamp therapy—also known as red light therapy (RLT) or low-level light therapy—is a non-invasive treatment that uses specific wavelengths of red and near-infrared light to stimulate cellular function. Originally researched for wound healing and tissue repair, it is now widely used for skin care, pain relief, muscle recovery, and general wellness.
Unlike ultraviolet (UV) rays from sunlight, red light therapy does not damage the skin. Instead, it penetrates tissue and supports cellular energy production, circulation, and repair processes.
How Red Light Therapy WorksRed light therapy works through a process called photobiomodulation. The light energy is absorbed by mitochondria (the cell’s energy producers), enhancing the production of ATP—the fuel cells use to function and repair themselves.
