See the benefits of each light option here: Blue Light (460-470nm) Blue light is best utilized to treat acne-prone skin or breakouts, as it kills surface level bacteria hiding in your pores and clears active breakouts. It reduces inflammation and redness, so you can enjoy a marked difference in your skin as soon as possible. Yellow Light (580-590nm) Stimulating circulation and red blood cells, the yellow light works a little deeper into the skin to help fight toxins and improve lymphatic function. This light is most beneficial in treating sun damage or pigmentation. Red Light (620-630nm) A favourite for treating the signs of ageing such as fine lines and wrinkles, the red light delivers energy at a cellular level to encourage collagen and elastin production, rejuvenating the skin from within. This is also a good option for improving the overall hydration of the skin.
