Used and recommended by Estheticians, Dermatologists, and Plastic Surgeons for over a decade. Just like plants, our skin and other body tissues have the ability to absorb light and convert it into energy. LightStim LED light therapy delivers 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 tool 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.
