Far-infrared light energy is absorbed up to 3” into the skin, stimulating blood flow and delivering blood cells rich in oxygen and nutrients to the skin. The process also stimulates production of collagen, the most common protein in the body. Collagen is essential to repair damaged tissue and replace old tissue and contributes to the elasticity of youthful-looking skin. As mammals, we receive collagen from sunlight.
