The Cleveland Clinic's View on LED Red Light Therapy


We'd like to share a conservative analysis of the potential benefits and risks of LED red light therapy for those of you who would appreciate a measured medical review by one of the world's leading medical institutions: The Cleveland Clinic. Here are some excerpts and the full report is linked below.

"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."

"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. It’s used to treat some skin conditions, including skin cancer and psoriasis, acne and warts and other types of cancer."

"Most researchers say results so far look promising, but that more quality studies with larger numbers of people are needed."

"Everyone’s skin is different so results can vary. Also, the wavelength of the red light source ranges. The wavelength affects how deeply the light penetrates your skin. The wavelength of the red light device being used in a doctor’s office versus in your at-home device could affect your desired result."

"Other potential medical uses being investigated include:
- To reduce cancer chemotherapy side effects, including oral mucositis.
- To relieve pain and inflammation associated with ankle tendonitis, rheumatoid arthritis, carpal tunnel syndrome and osteoarthritis of the knee.
- To prevent cold sores from herpes simplex virus from recurring."

"Red light therapy is being promoted as a treatment for some common skin conditions. It’s still an emerging therapy but holds a lot of promise. If you’re interested in RLT treatment, it’s best to first discuss this with your healthcare provider or dermatologist."
