LightStim delivers light energy in a similar way plants absorb light energy from the sun. Each LightStim device uses different wavelengths, or colors of light. LightStim for Pain emits light energy that reduces pain and temporarily increases local blood circulation.  LightStim for Acne uses blue light to destroy acne-causing bacteria, and red light to help soothe and calm the skin. This helps clear existing breakouts in order to give you visibly improved, healthy-looking skin. LightStim for Wrinkles provides rejuvenating wavelengths of light energy to treat fine lines and wrinkles. Over time by using your Light you can help to recapture a plump, youthful appearance.
