How deep does the Q.Light light penetrate through the skin surface?
Light waves of different wavelengths penetrate through our skin at unequal depths. Violet light and blue light components penetrate least through skin while orange and red light components penetrate deepest. In this way, the immune system is stimulated since visible light reaches blood cells through fine capillaries close to the skin surface (= photo modulation of blood). That is how the biopositive effect of Q.Light light therapy is transported by our blood the entire body.
