Red light therapy causes a photochemical reaction within our cells to increase adenosine triphosphate (ATP) production in the mitochondria, by activating an enzyme called cytochrome c oxidase (Cox) that plays a role in generating ATP synthase (the enzyme that produces ATP). ATP is the major energy currency of our cells, and when red LED light increases its levels in our tissue, we essentially have more of this currency to use for transporting energy needed for all of the metabolic activities of our cells! As a consequence of this ATP boost, we can experience more rapid healing. Red light therapy can also increase our collagen production, and deliver all the skin and joint benefits.
