Does Red Light Therapy work?

Is there any science that proves red light therapy works.

Hi Jennifer,
yes there is scientific research behind the use of red light therapy.

One study from the University of Ulm in Germany has tested the red light around the eyes for 90 seconds daily for 10 month. The result has been a significant reduction of the wrinkles and overall skin rejuvenation.

The scientist investigated how water molecules in the skin interact with different substances. They found that water molecules close to a hydrophobic, or "water-hating", substance formed a slippery crystalline layer, while those surrounding a hydrophilic, or water-loving, substance were glue-like.

Elastin, the fibrous protein that gives skin its elasticity and so counteracts wrinkling, is hydrophobic. But as we age, fatty acids, amino acids and calcium salts build up on the elastin fibres, making them hydrophilic. So the water film around the fibres becomes increasingly glue-like, causing them to stick to the surrounding tissue and reducing their elasticity.

Previous studies have suggested that red light with a wavelength of around 670 nanometres can make water molecules close to hydrophilic substances more mobile.

All the best.
