Red light and near-infrared light help stimulate the production of collagen, which is directly connected to the elasticity, firmness, and fullness of the skin.

Red light penetrates deep into the skin and promotes tissue repair, wound healing, and skin rejuvenation.

Thanks to its ability to stimulate the production of collagen and rebuilding cartilage, red light therapy is now being used to treat the symptoms of arthritis.

Red and NIR light wavelengths have been shown to stimulate energy production within the Leydig cells, which are the cells responsible for producing testosterone in the testicles. Enhanced energy production in Leydig cells is believed to help naturally increase testosterone production.

Along with Leydig cells, all cells in the body benefit from increased energy production. Just as you can perform at your peak when you feel energized, your cells do as well. Red light therapy has many benefits, and they all stem from the positive interaction between light photons and the mitochondria, or the energy centers within each cell in the body. This powerful stimulating effect on the body’s cells has been shown in hundreds of clinical studies.

According to one study, red light therapy helps increase hair follicle activity which improves hair thickness and density.

Red light therapy improves the body’s ability to metabolize fat. This therapy helps in dispersing adipocytes, which are cells that store fats.

Red light therapy has also been effective in alleviating depression and anxiety by elevating your mood.

Researchers at the University of Texas applied infra-red light on the foreheads of volunteers and measured its effects of cognitive parameters. They observed an improvement in reaction time, memory and a positive emotional state.
