How Does Red Light Therapy Work

Red light therapy is an effective, scientifically proven treatment that offers many benefits and applications, from muscle repairs to healthy aging. Whether you use red light therapy for scar healing, pain reduction, or sleep assistance, the science behind this multifaceted treatment remains the same. Check out this brief guide on red light therapy facts and discover the science behind how red light therapy works.

What Is Red Light Therapy?

Red light therapy is an FDA-approved and non-invasive therapeutic treatment that generates light-induced photochemical reactions in your body, also known as photobiomodulation. RLT uses red or near-infrared light to stimulate cellular processes in the body. Unlike blue light, red light and infrared light can penetrate deeper into the skin, reaching your fat cells, muscles, and even bones.

How Does Red Light Therapy Work?

RLT sends red or near-infrared light waves to the powerhouse of cells—the mitochondria—which produces the energy needed to power your cell’s various biochemical reactions, from cellular repairs and restoration to rejuvenation. Stimulated energy generates your body’s fuel, like Adenosine Triphosphate (ATP), for many biochemical reactions, such as:

  • Vasodilation: The widening of blood vessels that leads to increased blood flow and improved circulation, delivering more oxygen and nutrients around your body and expediting healing processes.
  • Collagen production: Essential for maintaining skin elasticity, resilience, and hydration. Collagen maintains the tissue’s structural framework.
  • Fibroblast generation: Fibrous cellular material contributes to the formation and maintenance of connective tissue, improving skin healing and muscle regeneration.
  • Skin cellular turnover: A natural process that involves newly generated cells from the innermost layer of your epidermis, the basal layer, moving upward to the surface layer of your skin, removing and replacing older and dead skin cells and leaving you with youthful skin.
  • Antioxidant production: ATP from the mitochondria promotes the production of your body’s antioxidants, which play a major role in repairing, soothing, and rebuilding muscles.

So, how does red light therapy work? Red light therapy uses photobiomodulation to target your cells’ mitochondria, promoting, improving, and supporting many essential biochemical reactions in your body, from healing to maintenance. Since RLT stimulates multiple systems in your body, undergoing RLT offers many benefits and applications, including sports injury rehabilitation, aesthetic treatments, and chronic pain management.
