Red and infrared light (NIR) can penetrate the skin deeper than almost any other light wavelength. The key characteristic of infrared light is its ability to penetrate even the deep layers of the skin, providing greater pain relief.
Red light therapy devices that combine both red light and near infrared light offer potent healing potential because they incorporate a range of therapeutic wavelengths. These wavelengths can target diverse issues. For example, red light wavelengths can penetrate to the depth of the skin, promoting collagen production and healing wounds, while near infrared light is able to penetrate deeper into the body’s tissue to more successfully target deep wounds, muscle, or joint pain.
Also, infrared light is safe, natural, non-invasive, and painless. Thus, it may be able to provide a broad range of health benefits.
