What exactly is red and near infrared light therapy? Light therapy, sometimes referred to as photobiomodulation, is a non-invasive form of therapy that involves using LED lights to deliver specific wavelengths of natural light to your skin and cells. More specifically, Our Hooga Red Light Therapy panels delivers red (660nm) and near infrared (850nm) wavelengths of natural light at varying powers which allows you to enjoy the benefits of red and near infrared light therapy in a few minutes, all from the comfort of your home.
