With help from NASA, doctors at the Medical College of Wisconsin have been proving that LED lights emitting the same near-infrared frequency used in space station agricultural has a dramatic effect on wound healing.

The wound-healing device is a 9 by 11 centimeter array of LED’s that is placed on the outside of the patient’s cheek for only a minute per day. The light, made by Quantum Devices using a trick of quantum physics to produce previously unobtainable frequencies, easily penetrates the inside of the mouth.
