What is Red Light Therapy?

Red light therapy, also known as low-level light therapy (LLLT), is a non-invasive therapeutic technique that uses red light wavelengths to promote healing and alleviate various health conditions. This therapy has been gaining popularity in recent years due to its potential to improve skin health, relieve pain, and enhance overall well-being.

How does Red Light Therapy work?

Red light therapy works by exposing the body to a specific wavelength of red light, which is absorbed by the skin and underlying tissues. This light triggers a process called photobiomodulation, which stimulates the production of cellular energy (ATP), increases blood flow, and promotes healing.

The red light wavelengths used in this therapy are typically in the range of 630-660 nanometers (nm), which is known to penetrate the skin deeply and stimulate collagen production. Collagen is an essential protein that makes up the skin, bones, and connective tissues in the body. As we age, our body's ability to produce collagen decreases, leading to wrinkles, sagging skin, and other signs of aging. Red light therapy can help to stimulate collagen production and improve skin texture, tone, and elasticity.

Benefits of Red Light Therapy

Improves Skin Health
Red light therapy is known for its ability to improve skin health and reduce signs of aging. It has been shown to promote collagen production, which helps to reduce fine lines and wrinkles, and improve skin texture, tone, and elasticity. Additionally, red light therapy can help to reduce inflammation and redness, making it an effective treatment for acne, rosacea, and other skin conditions.

Relieves Pain
Red light therapy has been shown to have analgesic (pain-relieving) effects, making it a popular treatment for chronic pain conditions such as arthritis, fibromyalgia, and back pain. It works by increasing blood flow to the affected area, reducing inflammation, and promoting the release of endorphins (natural painkillers).

Enhances Athletic Performance
Red light therapy has been shown to improve athletic performance by increasing energy production in cells, reducing muscle fatigue, and promoting muscle recovery. It has also been shown to increase muscle mass and strength in some studies.

Improves Mental Health
Red light therapy has been shown to have mood-enhancing effects, potentially helping to alleviate symptoms of depression and anxiety. It works by increasing blood flow to the brain, stimulating the production of neurotransmitters, and reducing inflammation.

Helps with Wound Healing
Red light therapy has been shown to promote wound healing by increasing blood flow to the affected area, promoting the growth of new blood vessels, and stimulating the production of collagen. It has been used to treat a variety of wounds, including diabetic foot ulcers, surgical wounds, and burns.


Red light therapy is a non-invasive, safe, and effective therapeutic technique that has many potential benefits for health and well-being. It is a promising treatment for various health conditions, including skin health, pain relief, athletic performance, mental health, and wound healing. If you are interested in trying red light therapy, talk to your healthcare provider to see if it's right for you.
