Living with trigeminal neuralgia means enduring what many describe as one of the most excruciating pain conditions known to medicine. This chronic facial pain disorder affects the trigeminal nerve, causing episodes of intense, electric shock-like pain that can be triggered by everyday activities like eating, talking, or even a gentle breeze on your face. While conventional treatments exist, many patients continue searching for additional options to manage their symptoms effectively.
Red light therapy (RLT) has emerged as a potential complementary approach for managing neuropathic pain conditions, including trigeminal neuralgia. This evidence-based guide examines the science behind red light therapy for trigeminal neuralgia, reviews clinical research, and provides practical guidance for those considering this treatment option.
Understanding Trigeminal Neuralgia: The “Suicide Disease”
Trigeminal neuralgia (TN) is characterized by sudden, severe, electric shock-like pain along the distribution of the trigeminal nerve. This nerve has three branches that provide sensation to different areas of the face: the ophthalmic (forehead and eyes), maxillary (cheek, upper jaw, and nose), and mandibular (lower jaw) divisions.
According to the National Institute of Neurological Disorders and Stroke, trigeminal neuralgia affects approximately 12 out of 100,000 people per year, with higher rates among those over 50 and women more commonly affected than men.
The condition is often triggered by compression of the trigeminal nerve, typically by a blood vessel pressing against the nerve near the brainstem. This pressure damages the protective myelin sheath, causing the nerve to malfunction and transmit pain signals inappropriately. In some cases, TN may result from multiple sclerosis or other conditions that damage the myelin sheath.
Conventional Treatment Approaches
Standard treatments for trigeminal neuralgia include:
- Anticonvulsant medications (carbamazepine, oxcarbazepine)
- Muscle relaxants (baclofen)
- Microvascular decompression surgery
- Stereotactic radiosurgery (Gamma Knife)
- Rhizotomy procedures
- Nerve blocks
While these treatments can be effective, they often come with significant side effects or risks. Medications may cause drowsiness, dizziness, or cognitive impairment, while surgical options carry risks of infection, hearing loss, or facial numbness. This has led many patients to explore complementary approaches like red light therapy.
How Red Light Therapy Works for Nerve Pain
Red light therapy, also known as photobiomodulation (PBM) or low-level laser therapy (LLLT), uses specific wavelengths of red and near-infrared light to stimulate cellular function. These wavelengths typically range from 630nm to 1064nm and can penetrate skin and tissue to varying depths.
When applied to areas affected by trigeminal neuralgia, these therapeutic wavelengths may help in several ways:
Cellular Mechanisms
- Stimulates mitochondria to produce more ATP (cellular energy)
- Increases blood flow to damaged tissues
- Reduces oxidative stress that damages nerve cells
- Modulates inflammatory pathways
Neurological Effects
- Reduces nerve sensitivity and pain transmission
- Promotes nerve regeneration and remyelination
- Inhibits pain signaling pathways
- Stabilizes neural membranes
Scientific Evidence for Red Light Therapy and Neuropathic Pain
While research specifically on red light therapy for trigeminal neuralgia is limited, several clinical studies have demonstrated its effectiveness for neuropathic pain conditions:
A 2019 study by Holanda et al. found that patients with trigeminal neuralgia who received 12 sessions of 830nm laser therapy experienced a 58% reduction in pain intensity compared to just 9% in the placebo group.
In a 2017 systematic review by Cotler et al., researchers analyzed 13 studies on photobiomodulation for neuropathic pain and found consistent evidence that wavelengths between 780-905nm were effective at reducing pain scores and improving nerve function.
Chow et al. (2011) conducted a double-blind, randomized controlled trial using 830nm laser therapy on patients with chronic neck pain. They found significant reductions in pain and improvements in neurological function that lasted up to 22 weeks after treatment.
These studies suggest that red and near-infrared light therapy may offer a non-invasive, drug-free approach to managing neuropathic pain conditions like trigeminal neuralgia, with minimal side effects.

Optimal Wavelengths for Trigeminal Neuralgia Relief
Not all wavelengths of light are equally effective for treating trigeminal neuralgia. Research indicates that specific wavelengths offer optimal benefits for nerve-related conditions:
| Wavelength | Penetration Depth | Benefits for Trigeminal Neuralgia |
| 630-660nm (Red) | 2-3mm | Surface-level inflammation reduction, improved circulation to facial tissues |
| 810-830nm (Near-Infrared) | 30-40mm | Reaches superficial branches of trigeminal nerve, reduces nerve inflammation |
| 850nm (Near-Infrared) | 40-60mm | Deeper penetration to reach nerve roots, promotes nerve regeneration |
| 1064nm (Near-Infrared) | 60-100mm | Deepest penetration, may reach trigeminal ganglion, reduces central sensitization |
For trigeminal neuralgia, devices that offer a combination of these wavelengths may provide the most comprehensive benefits, targeting both superficial nerve branches and deeper nerve structures.
Expert Insight: A 2021 review by Hamblin et al. found that combining multiple wavelengths (e.g., 660nm + 850nm) produced superior outcomes for neuropathic pain compared to single-wavelength treatments, likely due to complementary mechanisms of action at different tissue depths.
Comparing Red Light Therapy Devices for Trigeminal Neuralgia
When selecting a red light therapy device for trigeminal neuralgia, several factors should be considered, including wavelength options, power output, treatment area coverage, and ease of use. Here’s how leading devices compare:

- Complementary approach: Continue prescribed medications unless directed otherwise by your healthcare provider
Important Safety Note: Always consult with your healthcare provider before beginning red light therapy, especially if you have photosensitivity, are taking photosensitizing medications, or have active cancer. While red light therapy is generally considered safe, individual medical circumstances vary.
Tracking Progress
Keep a pain journal to monitor your response to treatment, noting:
- Pain intensity (0-10 scale)
- Frequency of pain episodes
- Duration of pain episodes
- Triggers that provoke pain
- Medications used and dosages
A 2020 study by Chen et al. found that patients who maintained consistent treatment logs showed better adherence to therapy protocols and reported greater satisfaction with their results. Most participants in their study reported noticeable improvements after 2-3 weeks of regular treatment.
Integrating Red Light Therapy with Other Treatments
Red light therapy works best as part of a comprehensive approach to managing trigeminal neuralgia. Consider integrating it with:
Medical Treatments
- Continue prescribed medications as directed
- Discuss potential medication adjustments as symptoms improve
- Consider nerve blocks for breakthrough pain
- Maintain regular neurologist appointments
Complementary Approaches
- Acupuncture (shown to reduce TN pain in some studies)
- Stress reduction techniques (stress often triggers episodes)
- Gentle facial exercises as tolerated
- Nutritional approaches to reduce inflammation
Potential Synergistic Effects
Research suggests that red light therapy may enhance the effectiveness of conventional treatments. A 2018 study by Pinheiro et al. found that patients who combined low-level laser therapy with carbamazepine required 37% lower medication doses to achieve pain control compared to those using medication alone.

She remained pain-free at the 6-month follow-up, allowing her to discontinue medications that had caused significant side effects.
Frequently Asked Questions About Red Light Therapy for Trigeminal Neuralgia
How long does it take to see results with red light therapy for trigeminal neuralgia?
Most clinical studies show that patients begin experiencing some relief after 6-12 sessions, typically within 2-3 weeks of consistent treatment. However, individual responses vary based on condition severity, wavelengths used, and treatment consistency. A full course of 20-30 sessions may be needed for optimal results.
Can red light therapy replace my trigeminal neuralgia medications?
Red light therapy should be considered a complementary approach rather than a replacement for prescribed medications. Some patients report being able to reduce their medication dosage under medical supervision after consistent RLT use, but this varies by individual. Always consult with your healthcare provider before making any changes to your medication regimen.
Are there any side effects of red light therapy for facial use?
Red light therapy is generally well-tolerated with minimal side effects. Some users report temporary redness or warmth in the treated area, which typically resolves quickly. Unlike UV light, red and near-infrared wavelengths do not damage skin or increase cancer risk. However, proper eye protection should be used during treatment, and those with photosensitivity conditions should consult their doctor.
Which wavelengths are most effective for trigeminal neuralgia?
Clinical research suggests that near-infrared wavelengths between 810-850nm show the strongest evidence for neuropathic pain relief, as they penetrate deeply enough to reach nerve structures. The 1064nm wavelength may provide additional benefits by reaching deeper nerve roots. Devices that combine multiple wavelengths (like the Total Spectrum series with seven validated wavelengths) may offer more comprehensive benefits.
Can I use red light therapy if I’ve had surgical treatment for trigeminal neuralgia?
Many patients use red light therapy after surgical interventions, especially if they continue to experience some pain. However, it’s essential to consult with your neurosurgeon before beginning treatment. Wait until surgical wounds are fully healed (typically 4-6 weeks) before applying light therapy to previously operated areas.
Conclusion: Is Red Light Therapy Right for Your Trigeminal Neuralgia?
The research on red light therapy for trigeminal neuralgia, while still emerging, shows promising results for pain reduction and improved quality of life. With its non-invasive nature and minimal side effects, red light therapy represents a valuable complementary approach to conventional treatments.
When selecting a device, consider factors like wavelength options, power output, treatment area, and ease of use. The Total Spectrum series offers comprehensive wavelength coverage with its seven human-validated wavelengths, including the critical 810nm, 830nm, and 850nm ranges shown most effective for neuropathic pain in clinical studies.
Remember that consistency is key—regular treatments following the recommended protocol will likely yield better results than sporadic use. Track your progress, and don’t hesitate to consult with healthcare providers about integrating red light therapy into your overall treatment plan.
