Red Light Therapy Explained: Wavelengths, Sessions, and Devices

Red Light Therapy Explained

Red light therapy, also called photobiomodulation, uses low-level red and near-infrared light. Home devices are now common, and this guide explains the basics: what the wavelengths are, how sessions are typically set up, and how to choose among AWA devices.

What Is Red Light Therapy?

Red light therapy uses specific wavelengths of red and near-infrared light, typically in the 630 to 850 nanometer range. Unlike sunlight, these devices do not use ultraviolet light.

The most commonly used wavelengths are 660 nanometers (red) and 850 nanometers (near-infrared). Near-infrared light is absorbed at greater depth than red light. Devices such as the FX500 Red Light Therapy Panel and the FX300 Red Light Therapy Panel combine both wavelengths.

Research Background

Photobiomodulation research looks at how cells absorb red and near-infrared light. The mitochondrial enzyme cytochrome c oxidase is often discussed as one of the light-absorbing molecules involved. Research in this area is ongoing.

Device Types

• Panels such as the FX500 cover larger areas of the body.
• Face masks such as the LX500 LED Light Therapy Mask are worn on the face.
• Wraps such as the Red Light Therapy Belt wrap around parts of the body.
• Handheld devices such as this handheld red light therapy device are used on smaller areas.

How Often Is Red Light Therapy Used?

Commonly used routines are 10 to 20 minute sessions, three to five times per week, with the device placed 6 to 12 inches from the body. Follow the instructions that come with your device.

Choosing a Red Light Therapy Device

The right device depends on the area you want to cover and how you plan to use it. For larger areas, a panel such as the FX500 is an option. For the face, the LX500 LED Light Therapy Mask is worn directly on the face.

Red Light Therapy Safety

Use your device as directed. Eye protection is recommended for direct exposure to bright panels, and people on photosensitizing medications should consult a healthcare provider first.
