What is polychromatic light therapy?

Polychromatic light therapy (PLT) simultaneously uses 2 or more wavelengths or light sourcing from LED lights. PLT’s bioeffects are called photobiomodulation (PBM).

PLT penetrates tissue to various depths and is then absorbed by the cells to produce the energy needed for cell regeneration and repair resulting in restoration and improvement of health. 

The infrared (blue or red) light’s synthetic effect allows both colors to get into the tissue more deeply than in a monochromatic application. PLT application also assists in the release of nitric oxide, leading to improved circulation, which is one of the key components of the healing and benefits at the cellular level. There is no other medical intervention that can match these unique changes. PLT therapy pad by InLight targets multiple areas of concern. 


What is photobiomodulation?

Photo (light), Bio (biology), Modulation (change)

Our body needs light for optimal health. Every cell of a mammal is composed of photo light receivers. The pulsed light triggers the release of nitric oxide and activates the anti-inflammatory proteins. Nitric oxide is the Nobel Prize-winning signaling molecule released with PLT.

Pain Relief & Wellness

Symptoms of impaired circulation and pain can bring positive results when associated with following conditions:

  • Inflammation/swelling
  • Bone fractures
  • Burns
  • Joint pain
  • Bruises
  • Skin conditions
  • Mood disorders
  • Wounds that don’t heal
  • Tight muscles
  • Peripheral neuropathy


The better we comprehend the benefits of improving circulation, the easier it is to understand why low-level PLT supports the body’s recovery process and provides additional health benefits.

InLight PLT is a non-invasive FDA approved Class ll Medical Device used to temporarily relieve minor pain, increase local blood circulation, stiffness and muscle spasm.

How does polychromatic led technology work?

Light is a fundamental nutrient for our bodies. The sun’s light has been used as therapy for thousands of years. The evolution of science has made beneficial wavelengths of the sun’s light into LLLT accessible.

InLight Therapy has been manufacturing LLLT devices for 30 years. PLT is a unique therapy that has the strength of near-infrared (NIR) light and unlike red, yellow and blue light is not visible to the eye. At the area of treatment NIR has the properties to dilate blood vessels with a fast feeling of improved comfort, sensation and regeneration.
