Red light therapy, also known as photobiomodulation therapy, is the use of clinically-determined wavelengths of red and near-infrared light to increase circulation and the synthesis of cellular energy. The natural metabolic processes enhanced by red light therapy help reduce the damaging effects of oxidative stress. Oxidative stress, or an influx of free radicals in the body, has been linked to wrinkles as well as more serious diseases like diabetes and cancer. Red light therapy helps promote the body’s natural processes for metabolizing free radicals, minimizing the damage they cause.
