Light therapy vs. photobiomodulation: what are the differences and how do you choose?

In short: Light therapy and photobiomodulation are two light-based therapies that are often confused. Light therapy uses intense white light that affects the body’s circadian rhythm and mood, while photobiomodulation uses red and near-infrared wavelengths that penetrate the tissues to stimulate cells. Their mechanisms, indications, and protocols differ, which helps guide the choice based on the desired outcome.
