What is Red Light Therapy?
Red Light Therapy (RLT), also known as Photobiomodulation (PBM), is a non-invasive treatment that uses specific wavelengths of red and near-infrared light to support cellular function, reduce inflammation, and promote healing. It has been studied for its benefits on skin health, pain relief, brain function, muscle recovery, and more.
Unlike UV light, which can damage the skin, red and near-infrared light penetrate deeper into the body, interacting with cells to boost energy production and reduce oxidative stress.
Why Wavelengths Matter
Not all red light is the same! The effectiveness of Red Light Therapy depends on wavelength, measured in nanometers (nm).
- Visible Red Light (630-660nm)
- Best for skin treatments, wound healing, and surface-level concerns like acne and collagen production.
- Near-Infrared Light (810-850nm)
- Penetrates deeper into tissues, supporting muscle recovery, joint pain relief, brain function, and inflammation reduction.
Different wavelengths target different parts of the body, which is why understanding light absorption is key to getting the best results.
What About Power & Irradiance?
Another important factor is irradiance, which refers to the power of light delivered to your body (measured in mW/cm²).
- Too low, and you won’t get effective results.
- Too high, and there’s no added benefit—more isn’t always better!
Most studies suggest that an effective range is around 20-100mW/cm², depending on treatment distance and session duration.
Sounds Like Snake Oil? We Get It!
Red Light Therapy can sound too good to be true, but we’re not here to sell you hype. Instead, we encourage you to look at the science yourself.
There are thousands of peer-reviewed studies exploring the benefits of red light on the body. That’s why we’ve compiled real research summaries for you to explore the evidence and make an informed decision.

How to Get Started
- Choose the Right Wavelengths – Use 630-660nm for skin and 810-850nm for deeper healing.
- Find a Light Source – Any device with proven wavelengths and effective irradiance can work (even affordable options).
- Start with Short Sessions – 5-10 minutes per area, 3-5 times per week.
- Be Consistent – Results happen over weeks, not overnight.
