LED light therapy is simply amazing. It’s a proven technology that delivers light energy in a way similar to how plants absorb light energy from the sun. It emits UV-free, beneficial light energy to the skin. And each LightStim product uses different wavelengths of light: red, blue, green and amber. When this beneficial light is applied directly to the skin it can reduce fine lines and wrinkles, temporarily increase blood circulation, and treat mild to moderate acne. The in-home hand-held LightStim products are simple safe to use and you’ll see results fast.
