Red Light Therapy, Near-Infrared Light, and Photobiomodulation Explained

Red light, near-infrared, and photobiomodulation are often used interchangeably. Here is what each term actually refers to and what to expect from a clinical session.

Quick answer

Photobiomodulation (PBM) is the broad term for low-level light therapy. Red light and near-infrared light are specific wavelength ranges used within PBM. Clinical-grade panels deliver these wavelengths in sessions that typically run 10 to 20 minutes.

Terminology in plain English

Photobiomodulation describes the use of specific wavelengths of light to interact with tissue at a cellular level. Red light and near-infrared light are the two wavelength categories most commonly referenced in clinical and wellness contexts.

What the modality is used to support

In a wellness context, photobiomodulation is used to support recovery, skin quality, and general well-being. It is not a treatment for any specific disease, and outcomes vary by individual and protocol.

What a session is actually like

Sessions are short, non-invasive, and comfortable. You stand or sit in front of a full-body panel for 10 to 20 minutes, with eye protection provided. Many clients pair a Red Light session with another therapy on the same visit.
