How Red Light Therapy Works
Red light therapy, also called photobiomodulation, uses specific wavelengths of light—around 660 nanometers (red) and 830 nanometers (near-infrared)—to affect how your cells work. The light is absorbed by an enzyme in your cells called cytochrome c oxidase, which is found in the mitochondria. These are the parts of the cell that make energy.
When the light hits this enzyme, it causes a molecule called nitric oxide to release. This allows the enzyme to start working again, which helps the cell produce more ATP—your cell’s energy source. That energy powers important tasks like repair, protein building, and healthy cell growth.
The light also triggers a small, controlled increase in reactive oxygen species (ROS). These act as signals, telling your cell to activate genes that support healing, collagen production, better blood flow, and antioxidant defense. At the same time, signals that cause inflammation begin to go down.
For red light therapy to work properly, the light must be at the right strength and reach the right depth. The device should stay close to the skin with no gaps, and sessions usually last between 5 and 20 minutes. The amount of energy and how long you use it affect how your skin responds.
