Red Light & Infrared Therapy for Home Use — explore LED light therapy and infrared wellness for different applications.
Start with the Red Light Therapy Knowledge Center for an explanation of how it works, wavelengths, dose, use and evidence.
Evidence-informed approach
Red light therapy is commonly used as a consumer term for photobiomodulation (PBM). Research covers different applications, and the strength of evidence varies by goal, protocol and device.
660 nm is visible red light. 830–850 nm is near-infrared. Wavelength alone does not determine an outcome; irradiance, distance, treatment time and total dose also matter.
We therefore describe what a technology may support or may contribute to. We do not provide medical outcome guarantees, and research on a specific PBM protocol cannot automatically be applied to every consumer device.
Which option fits your goal?
- Face or skin? Consider an LED mask.
- Scalp and hair? Consider a scalp helmet.
- A specific body area? Compare a belt or targeted device.
- A larger treatment area? Compare a panel or mat.
- Red light combined with heat and wellness? Explore infrared options.
Then compare wavelength, treatment area, irradiance when available, treatment time, distance, size and ease of use.
Frequently asked questions
What is red light therapy?
A form of light therapy using red and/or near-infrared light. PBM has been studied for different applications.
What is the difference between 660 nm and 850 nm?
660 nm is visible red light; 850 nm is near-infrared. They have different properties and may be combined depending on application and protocol.
Is higher wattage better?
No. Wattage describes electrical power and is not the same as irradiance or dose at the treatment surface.
How often should I use red light therapy?
Follow the instructions for the specific device. There is no universal frequency for every device.
Are results guaranteed?
No. Results vary by person, application, device and protocol.
Is red light therapy safe?
Follow the device instructions, safety information and eye guidance. If you have medical questions or concerns, seek professional advice.
