Red light therapy

Red light therapy (RLT), also known as photobiomodulation (PBM) or low-level laser therapy (LLLT), is a non-invasive treatment that utilizes specific wavelengths of red (630–700 nm) and near-infrared (800–1100 nm) light to stimulate healing and cellular function. Unlike ultraviolet (UV) light, which can damage the skin, red light is non-ionizing and penetrates deep into tissues—up to 6 millimeters—to interact with cells without producing heat or causing surface damage. It is delivered via various devices, including LED panels, face masks, laser combs, and full-body beds.
