The Research Behind Infrared

The research is in, and infrared therapy is one of the safest, most effective natural skin treatments that is currently on the market. Top skincare professionals recommend red light therapy to help with wrinkles, rejuvenation, acne, and healing injuries & scars.

Infrared is produced from medical grade LED’s that emit certain wavelengths of light. This delivers safe, concentrated wavelengths of natural light to your skin and cells, with no chemicals, UV rays, or excess heat. When the body is exposed to infrared, it is felt as a therapeutic heat. And unlike ultraviolet light – which has damaging effects upon the tissues and cells of the body – infrared light helps cells regenerate or repair themselves. So let’s dive into the research behind Infrared.

Skin, Cellulite, Acne, and Anti-aging

Collagen is the main building block for your bones, skin, hair, muscles, tendons, and ligaments. It should come as no surprise that an increase in collagen has anti-aging effects, smooth wrinkles, enhance skin tone, alleviates joint pain, along with a range of other benefits. In numerous scientific studies researchers measured the collagen levels before and after patients were exposed to infrared light. All studies found that infrared caused a substantial increase in collagen levels. [1,2,3,4,5,6,7]

Training and Muscle Recovery

A 2014 trial measured the infrared effects on muscular performance and recovery after exercise. The researchers found that infrared therapy “significantly increases performance, decreases DOMS, and improves biochemical markers related to skeletal muscle damage.” [8,9,10]

Inflammation and Joint pain

Infrared therapy has anti-inflammatory effects on human tissue. The increase in blood flow to skin cells alleviates both acute and chronic inflammation [11]. Scientific journals also support evidence that it increases the body’s antioxidant defences[12], a decrease in knee pain in osteoarthritis patients [13,14,15] a decrease in wrist pain in osteoarthritis patients [16] and a reduction in morning stiffness. [17]


Regular infrared therapy has been linked to an improvement in the quality of sleep in a 2012 study [18]. Another study in 2014 concluded that infrared was an effective tool for improving sleep in individuals suffering from traumatic brain injury [19]

“The research supporting light therapy is robust, and my own experience matches up with what is documented in scientific literature”

“Photo biomodulation has a wide range of clinically-proven health benefits. Everything from enhanced muscle recovery, to increased sexual performance, to improved skin health—and much more.”
