Beautiful Skin With advanced light technology™ Now you can benefit from advanced skin-clearing LED technology-anytime, anywhere. Unlike other light treatments, Pulse produces both red and blue light simultaneously from each individual LED which radiates a perfectly uniform wavelength of light to the skin. Blue light eliminates the bacteria in the skin, reducing current blemishes and preventing future breakouts. Red light reduces inflammation and redness in the skin. Red light also reduces the healing time of unsightly blemishes. Chroma 2® Technology combines the benefits of both blue and red light into one device, giving the light a purple.
