LightStim uses LED light therapy to deliver light energy in a similar way plants absorb light energy from the sun. LightStim emits UV-free, beneficial light rays that energize cells and stimulate the body's natural process to build new proteins and regenerate cells. Each LightStim product uses different wavelengths, or colors, of light. When this beneficial light is applied directly to the skin it helps to increase collagen and elastin production, reduce inflammation, speed healing, increase circulation, and destroy acne bacteria.
