What is Red Light Therapy

Understanding Red Light Therapy: What It Is and How It Works

Red light therapy is a non-invasive, science-backed treatment that uses specific wavelengths of red and near-infrared light to stimulate cellular activity. By energizing cells and supporting the production of adenosine triphosphate (ATP), it helps the body maintain its natural repair and maintenance processes.

Red light typically spans 620–700nm, while near-infrared light ranges from 810–850nm. These wavelengths reach surface tissues, like skin, as well as deeper layers such as muscles, joints, and connective tissue.

With consistent use, red light therapy can support healthier skin, improved muscle and joint function, and overall cellular vitality, offering a practical, non-invasive approach to enhancing overall wellbeing.

How Does Red Light Therapy Work?

Red and near-infrared light penetrates the skin and is absorbed by the mitochondria, the energy centers of your cells. This stimulates the production of adenosine triphosphate (ATP), fueling essential cellular processes and supporting natural repair.

The light also helps balance reactive oxygen species (ROS), molecules involved in inflammation and tissue signaling. Together, these effects promote healthier muscles, joints, and tissues, supporting overall cellular function and wellbeing.

Red Light vs. Near-Infrared Light: What’s the Difference?

Red light therapy involves multiple wavelengths, each designed to interact with the body in different ways. The specific wavelength determines how deeply the light penetrates the tissues and which cells it can influence, allowing targeted support for both surface and deeper structures.

Red light (620–700nm) primarily affects surface tissues like the skin. It can support skin health, collagen production, and minor tissue repair, helping improve skin texture, reduce fine lines, and address surface inflammation.

Near-infrared light (810–850nm) penetrates deeper layers, reaching muscles, joints, and connective tissues. This wavelength helps enhance circulation, muscle recovery, and joint function, complementing red light to provide a more comprehensive approach to overall wellness.
