Red light therapy has become one of the most widely used technologies in modern wellness and recovery. From professional athletes to everyday individuals, more people are using light-based treatments to support muscle recovery, skin health, and overall performance.
But what exactly is red light therapy — and how does it work?
This guide covers everything you need to know, including how red and near-infrared light interact with the body, the most common use cases, and how to choose the right device.
What Is Red Light Therapy?
Red light therapy, also known as photobiomodulation (PBM), is a non-invasive approach that uses specific wavelengths of light to support cellular function.
These wavelengths typically fall between 630 nm and 850 nm and are absorbed by the body to help support energy production and recovery processes.
Unlike treatments that rely on chemicals or mechanical stimulation, red light therapy works by interacting directly with the body at a cellular level.
How Does Red Light Therapy Work?
Red and near-infrared light penetrate the skin and are absorbed by mitochondria, the energy-producing structures inside cells.
This interaction may help support:
- cellular energy production (ATP)
- circulation and oxygen delivery
- tissue repair processes
- overall recovery response
While the underlying biology is complex, the key takeaway is simple: red light therapy is designed to support how efficiently your body produces energy and recovers.
Red Light vs Near-Infrared Light
Most modern devices use a combination of red and near-infrared wavelengths, each with different penetration depths.
| Light Type | Wavelength | Penetration | Primary Use |
|---|---|---|---|
| Red Light | 630–660 nm | Surface level | Skin and superficial tissue |
| Near-Infrared | 810–850 nm | Deeper tissue | Muscles, joints, and deep tissues |
Using both wavelengths allows devices to target multiple layers of tissue at once.
What About Blue Light?
While red and near-infrared light are commonly used to support deeper tissue function and recovery, blue light operates at a more surface level.
Blue light wavelengths — typically around 430 nm — are often used in skincare-focused routines to support skin clarity and balance.
When combined with red and near-infrared light, this creates a more complete, multi-wavelength approach — supporting both surface-level skin concerns and deeper cellular processes.
Modern light therapy devices increasingly integrate multiple wavelengths to deliver more versatile, full-spectrum treatment options.

Circulation
Light exposure may help support blood flow and oxygen delivery throughout the body.
How to Use Red Light Therapy
Most sessions involve exposing the body to light for a controlled period of time, typically 5–15 minutes per area.
General best practices include:
- consistent use several times per week
- maintaining proper distance from the device
- targeting specific areas of the body
Usage may vary depending on individual goals and the type of device used.
Choosing a Red Light Therapy Device
Not all red light therapy devices are created equal. When selecting a device, it’s important to consider:
- wavelength accuracy
- irradiance (output power)
- treatment coverage area
- build quality and durability
Higher-quality devices are designed to deliver consistent output across clinically relevant wavelengths — including red, near-infrared, and blue light — for a more complete treatment coverage..
