What is red light therapy?

Red light therapy uses specific wavelengths of red and near-infrared light to reach different layers of the skin and underlying tissue. The light is absorbed by the mitochondria—often described as the “powerhouses” of the cells—where it may help support the production of cellular energy, known as ATP.

This process may support the body’s natural recovery functions, promote healthier-looking skin, and help ease everyday muscle tension, stiffness, and discomfort.

The KEEPVA LumaPro 400 combines two carefully selected wavelengths to support both skin-focused and deeper-tissue applications.

660 nm Red Light
Primarily targets the surface and upper layers of the skin. It may help support collagen production, encourage skin renewal, and improve the appearance of fine lines, uneven skin tone, and other visible skin imperfections.

850 nm Near-Infrared Light
Penetrates more deeply into muscles, joints, and surrounding tissue. It may help support post-exercise recovery, ease muscle stiffness and discomfort, and promote the body’s natural recovery processes.
