What Is Red Light Therapy?

Red light therapy — sometimes called low-level light therapy or photobiomodulation — is the use of specific wavelengths of red and near-infrared light, delivered by LED devices, on the body. People use at-home devices as part of skincare and recovery routines, and it's also used in some professional and clinical settings.

Here's where we stay careful: there's a lot of research interest in red light, and also a lot of overstated marketing. We're not going to list health claims or promise results — effects vary by person and by device, and the science is still developing in many areas. What we can say plainly is what it is: targeted red and near-infrared light from an LED device, used on the skin or body. For whether it's appropriate for a specific goal or condition, a medical professional is the right source. More in red light therapy at home explained.
