Photobiomodulation is a process where low-energy wavelengths stimulate the metabolic functions of our tissues to produce several remarkable clinical effects, such as analgesic and anti-inflammatory effects, or healing effects. Light therapy uses a wide range of non-ionizing light sources such as lasers, LEDs, and visible light to provide therapeutic benefits to various parts of the body. Light therapy masks are a convenient and non-invasive method to stimulate cellular metabolism and achieve beneficial clinical outcomes.
