What Is Red Light Therapy? How It Works and What to Know Before a Session

Dr. Jeremy A Hunt Dr. Jeremy A Hunt | October 14, 2026 | 5 mins read

Red Light Therapy uses specific wavelengths of light and is sometimes incorporated into general wellness and skincare routines. Also known as photobiomodulation in some scientific contexts, it is an area of ongoing research. Outcomes can vary depending on the device, exposure settings, and individual circumstances.

Before trying a session, it helps to understand the difference between red and near-infrared light, what a session involves, and which suitability considerations to discuss beforehand.

What Is Red Light Therapy?

Red Light Therapy involves exposing the body to selected wavelengths of red light. Some devices also use near-infrared light, which is outside the visible range of human vision.

Although these types of light are related, they are not identical. Their properties differ, and the effects of exposure depend on factors such as wavelength, light intensity, exposure time, and the device being used.

Red light therapy is used in a range of settings, including some skincare and general wellness routines. However, research into particular applications should not be interpreted as proof that every device or session will produce the same results.

How Does Red Light Therapy Work?

Red and near-infrared light interact with biological tissues in ways researchers continue to investigate. One area of research is photobiomodulation, which examines how particular light exposures may influence cellular processes.

The biological response can depend on the wavelength, exposure parameters, device design, and individual circumstances. Findings from laboratory research or studies using a specific device do not automatically establish clinical benefits for other devices or applications.

For this reason, it is important to distinguish proposed biological mechanisms from demonstrated outcomes. Red Light Therapy should not be assumed to diagnose, prevent, or treat a health condition simply because a particular application is being researched.

What to Know Before a Red Light Therapy Session

Before attending a session, review the service information and follow the clinic’s instructions. Ask questions if you are unsure what the session involves or whether it is appropriate for you.

What Happens During a Session?

At Longevity Clinics Caringbah and Longevity Clinics Woolahra, the service uses a full-body light therapy bed that applies red and near-infrared light. The clinic lists five wavelengths: 630 nm, 660 nm, 810 nm, 850 nm, and 940 nm.

During the session, clients lie on the light therapy bed while red and near-infrared light is applied, following the clinic’s instructions. Ask the clinic about any precautions that may be relevant to your circumstances before starting.

How Long Does a Session Take?

The sessions last approximately 20–30 minutes, while its treatment list specifies a 30-minute service.

Allow time to review the instructions and discuss any questions before your session. Do not assume that longer exposure or more frequent sessions will produce better outcomes. Appropriate exposure depends on the device and its instructions.

Who Should Check Suitability Before a Session?

Red light therapy may not be suitable for everyone. Suitability depends on individual circumstances and the device being used.

Before arranging a session, tell the clinic about relevant health conditions, medications, and any history of photosensitivity. Also raise pregnancy, skin concerns, or eye conditions where relevant.

Some skin conditions may be aggravated by light exposure, and certain medications can increase sensitivity to light. If you have concerns about an existing condition or medication, seek advice from an appropriate healthcare professional before proceeding.

Do not stop or change prescribed medication without medical advice.

Red Light Relaxation: What Can You Expect?

Some people may choose a red light session as part of a general wellness routine or a period set aside for relaxation. However, subjective relaxation is not guaranteed, and the experience can differ between individuals.

At the Caringbah clinic, the session involves resting on a full-body light therapy bed while red and near-infrared light is applied. Ask the clinic what to expect in terms of preparation, positioning, and any precautions relevant to your circumstances.

It is also important to keep expectations realistic. A relaxing session does not establish that a particular medical or skincare outcome will occur.
