The key to understanding how polychromatic light therapy works is called photobiomodulation.

PHOTO (light)
BIO (biology)
MODULATION (change) 

Every mammalian cell is built with specialized photo acceptors to receive light. Our cells actually require light for the optimal function which means our bodies need light for optimal health. The body understands pulsed light as an instruction set triggering the release of nitric oxide and signaling the cell to produce anti-inflammatory and restorative proteins. Most notably, the Nobel Prize-winning signaling molecule nitric oxide is released with PLT. 

PLT is delivered via pulsed frequencies. These pulsed rates are another important instruction set used by the body to stimulate its self-healing processes. Inlight Therapy PLT systems deliver the healing benefits of polychromatic light using their Progressive Multi-Pulse™ technology. 

PLT triggers the release of nitric oxide which increases circulation to relieve pain and stimulates the body’s innate healing processes.
