Red Light Nasal Therapy: Discover the Promising Science of Intranasal Light Therapy

Introduction: A New Approach to Light-Based Wellness

Red light therapy is gaining attention as an innovative approach to wellness, skin care, recovery and photobiomodulation. While red light panels, face masks and therapy pads are already familiar to many people, another exciting area of research focuses on delivering light through the nasal cavity.

Known as intranasal photobiomodulation, this technique uses carefully selected wavelengths of red or near-infrared light to interact with biological tissue.

Researchers are exploring how this non-invasive technology may support different physiological processes, including those related to nasal health and other aspects of human biology.

At Goldenmont, we believe that understanding the science behind emerging wellness technologies helps consumers make more informed choices. In this article, we explore how red light nasal therapy works, what recent studies have discovered and why this innovative field is attracting scientific interest.

What Is Red Light Nasal Therapy?

Red light nasal therapy uses a small light-emitting device designed to deliver light at or inside the nostrils.

Unlike conventional red light therapy, which shines light onto the skin from the outside, intranasal devices are designed to position the light source closer to the nasal tissues.

Depending on the technology, devices may use red light, near-infrared light or both.

The underlying concept is photobiomodulation (PBM), a field of research investigating how particular wavelengths of light can influence biological processes without relying on the intense heating associated with some other light-based treatments.

This approach has attracted interest because it offers a different way to deliver light and investigate its interaction with the body.

How Does Intranasal Photobiomodulation Work?

Photobiomodulation research examines how red and near-infrared light may influence cellular activity.

One proposed mechanism involves mitochondria, the structures within cells that help generate energy in the form of adenosine triphosphate (ATP).

Researchers have investigated whether particular light wavelengths can influence mitochondrial activity and cellular signalling pathways involved in biological responses.

Intranasal photobiomodulation applies these principles using a light source positioned within the nose.

Scientists are investigating several areas:

• Cellular activity: How specific wavelengths may influence biological signalling.
• Nasal tissue responses: Whether intranasal light exposure can help improve certain nasal symptoms under defined clinical conditions.
• Circulation-related effects: How light-based approaches may influence selected blood-related and vascular processes.
• Wider physiological effects: Whether local light exposure can produce measurable effects beyond the directly illuminated tissue.

These mechanisms are still being investigated, and results depend on the wavelength, light dose, device design and treatment protocol.

What Does Scientific Research Say About Red Light Nasal Therapy?

One of the most encouraging developments is the growing number of clinical studies investigating photobiomodulation.

Although research is ongoing, some clinical trials have reported positive findings in specific applications.

1. Encouraging research into nasal symptoms

A randomized, placebo-controlled clinical trial published in 2025 in International Forum of Allergy & Rhinology investigated photobiomodulation in 62 patients with allergic rhinitis.

The researchers used a specific clinical protocol involving red and infrared light delivered inside the nose, alongside external infrared light.

The study reported improvements in several measures, including peak nasal inspiratory flow and patient-reported nasal obstruction symptoms.

These findings are encouraging because they suggest that photobiomodulation may have potential as an area of further research for nasal symptoms.

However, the trial evaluated a particular treatment protocol. It does not establish that every intranasal light device will produce the same results.

2. Research into the sense of smell

Another randomized clinical trial, published in 2025, investigated photobiomodulation in people experiencing smell disorders following COVID-19.

The study included 81 participants and compared control treatment with red-light and infrared-light treatment groups.

The treatment involved intranasal light therapy alongside other interventions, including medical treatment and olfactory training.

The researchers reported greater improvement in smell-identification scores in the infrared-light group compared with the control group.

This is a promising finding for the scientific investigation of intranasal photobiomodulation. However, the study was relatively small, and its results apply to the specific combination of treatments studied rather than to standalone consumer devices.

3. Growing evidence across photobiomodulation research

Interest in photobiomodulation extends beyond intranasal devices.

A 2025 umbrella review published in Systematic Reviews evaluated 15 meta-analyses covering 204 randomized controlled trials and more than 9,000 participants.

The review identified beneficial findings for several outcomes, including selected pain-related conditions, fatigue, hair density and disability associated with knee osteoarthritis.

The authors also emphasized that the certainty of evidence varied and that further high-quality research is needed.

While these findings do not establish the effectiveness of nasal therapy specifically, they demonstrate the breadth of scientific investigation into red and near-infrared light-based approaches.

Why Are People Interested in Intranasal Light Therapy?

Several features make intranasal photobiomodulation an interesting area of wellness innovation.

A non-invasive approach: Light-based techniques offer an alternative to approaches that require injections or surgical procedures, although suitability and safety depend on the specific device and intended use.

Targeted light delivery: Intranasal devices are designed to deliver light close to the nasal tissues rather than illuminating a broad external area.

An expanding research field: Clinical studies are exploring potential applications in nasal symptoms and other conditions, creating opportunities for further investigation.

Convenient device formats: Compact devices may offer a practical way to incorporate a light-based product into a personal routine when used according to the manufacturer’s instructions.

These features help explain the growing interest in intranasal photobiomodulation. They should not, however, be interpreted as a guarantee of clinical benefits.

Red Light vs Near-Infrared Light

Both red and near-infrared wavelengths are used in photobiomodulation research, but they differ in their interaction with biological tissue.

Actual penetration depends on tissue properties, wavelength and optical delivery. Near-infrared light does not automatically reach a particular organ or produce a specific health benefit.

When evaluating a device, look for clear wavelength specifications and reliable information about its optical output.

Safety and Responsible Use

Red light therapy is generally investigated as a non-invasive approach, but safety depends on the specific device and its intended application.

For responsible use:

• Follow the manufacturer’s instructions and recommended treatment duration.
• Do not exceed the specified exposure time.
• Stop using the device if you experience pain, irritation, bleeding or unusual discomfort.
• Seek medical advice before use if you have a relevant nasal condition, recent nasal surgery or a history of unexplained nosebleeds.
• Consult a healthcare professional if you have a condition or take medication that may affect light sensitivity.
• Do not replace prescribed treatment or delay medical care for persistent nasal symptoms.

Intranasal photobiomodulation should be viewed as an emerging area of research, not as a substitute for established medical treatment.
