Shining The Light On Red Light Therapy

Red light therapy or photobiomodulation is a non-invasive pain-free method of improving the body’s immune response. It’s an effective and safe method that uses light-emitting diodes(LED) that radiates the skin with a very specific wavelength. Also referred to as low-level laser therapy (LLLT), RLT has proven to be very effective in improving our general well being.

RLT is a painless and chemical-free technique that produces no heat and no contact is made with the skin. Studies has proven that red light therapy can be a drug-free alternative to several medical and cosmetic conditions.

Where does RLT come from?

The earliest mention of light therapy can be traced back to the greeks when they realized that exposure to light can have a positive effect on the healing of our bodies.

Moving on to the 1800’s, the Danish doctor Niels Finsen studied the effects of certain wavelengths on the treatment of tuberculosis and was later awarded the Nobel Prize for his studies.

In the 1960’s the first real breakthrough on light therapy was made by Dr.Endre Mester. He implanted tumor cells in rats and treated them with an ruby laser light in the hopes of destroying the tumor cells. To his disappointment the treatment did not work, however, he noticed that the cut made to implant the tumor cells healed a lot faster in the rats that were treated with the laser. His later research showed the potential of light therapy in the healing of muscle, skin and even nerve tissue.

In the 1990’s NASA did extensive research and several studies that shown the potential in space travel and also promote healing of humans and animals.

How does it work:

Light of a specific wavelength (630-660nm) is shined at the skin and penetrates it from 6-10mm deep. Once it diffuses into the skin it transforms into cellular energy and stimulates the mitochondria in our cells. This, in turn, has many effects on us, like:

  • Increase our energy levels
  • Stimulates the clean up of our cells.
  • Increase production of collagen
  • Restores our soft tissue
  • Stimulates the lymphatic system
  • Increase blood flow
  • Lowers the effect of free radicals.

When the body absorbs the red light the major consequence is the increase in ATP (adenosine triphosphate). ATP is the chemical energy in our cells and this boost of ATP is responsible for the healing effects of RLT.

Benefits of Red Light Therapy:

Repairing Soft Tissue and healing wounds.

The increase of the production cytokines reduces inflammation and stimulates cell repair.

Increase joint health

Numerous studies has proven that LLLT has a beneficial effect of arthritis and the relief of pain in joints. The increase production of collagen stimulates blood flow and rejuvenate the cells and helps to rebuild collagen.


The increase of collagen helps to repair skin tissue and reduce the marks of aging.

Hair loss

RLT stimulates the stem cells in hair follicles and moves it into the anagen (grow phase) and helps with the rebirth of the hair follicle.

Reduce the Effects of Cancer Treatments

NASA developed the HEALS device (High Emissivity Aluminiferous Luminescent Substrate) which shown the potential to increase the rate of cell recovery and reduce pain in cancer treatment.

RLT treatments can be done at home or one can go to specialized clinics for treatment.

The fact that it is a pain-free, non-invasive, chemical-free form of therapy has huge potential in the medical field.
