Red and near-infrared light are part of the electromagnetic spectrum, and more specifically, part of the spectrum of light emitted by the sun. These wavelengths of light are “bioactive” in humans.
Red light between 600-700nm offer benefits for skin texture and tone, smoothing fine lines and wrinkles, promoting collagen production and generally rejuvenating the appearance of skin and hair.
Near-infrared light (NIR) 700nm – 1100nm. penetrates deeper into the tissues to assist with wound healing, muscle recovery, nerve injury, and joint pain.

NASA originally began experimenting with red light therapy on plant growth in space and then to help heal wounds in astronauts. Like many developments, other potential uses began to be investigated.
In fact, red light therapy is already widely medically accepted in its use in photodynamic therapy. In this therapy, low-power red laser light is used to activate a photosensitizer drug. The interaction creates a chemical reaction that destroys cells and is used to treat some skin conditions. (Cleveland Clinic)
Red light therapy is thought to work by acting on the “power plant” in your body’s cells called mitochondria. With more energy, other cells can do their work more efficiently, such as repairing skin, boosting new cell growth, and enhancing skin rejuvenation. More specifically, certain cells absorb light wavelengths and are stimulated to work.
