I hope this detailed Vielight Review will help you to decide whether or not you want to invest in one of these devices for yourself. You can read the whole review or just jump ahead to the end to see the Conclusions and the Pros and Cons.

Vielight Intranasal and Transcranial Light Therapy, is a type of Photobiomodulation Therapy, which also includes Low Level Laser Therapy (LLLT). It is a simple, safe and effective way to improve your general wellness with just 25 minutes of use each day.

The small intranasal light clips onto your nose and illuminates the dense network of capillaries inside the nasal cavity. In addition, the transcranial devices fit over your head and illuminate specific regions of the brain.

Vielight technology is based on decades of scientific research. Scientists in Russia, Eastern Europe, China and other countries have researched the effects of light energy of specific wavelengths (colors) and intensities on blood of laypeople and athletes.

The benefits are comparable to what can be achieved by intravenous blood irradiation performed in medical centres, but without the need for doctors or needles.

There are three intranasal Vielight Devices: the Vielight 633 Red and the Vielight 655 Prime emit red light for general wellness, while the Vielight 810 Infrared emits infrared light for the brain and nervous system as well as general wellness.

There are also four powerful Vielight Devices with transcranial LEDs, which actually shine through the skull to provide brain therapy: the Vielight Neuro Alpha, the Vielight Neuro Gamma, Vielight Neuro Duo and the Vielight X-Plus. I will cover all seven Vielight Devices in this detailed Vielight Review.

I have been using a Vielight 655 Prime for more than five years, even taking it on long overseas trips, and it has always worked perfectly without problems. It is simple to use and the rechargeable AA battery (not included) lasts me for several weeks of almost daily use.

While it is hard to put good health down to just one thing, I have maintained remission from cancer for six years and I stay well even when many around me get colds and flus. I consider the Vielight 655 an important component of my general health regime, and after the initial investment there are no ongoing costs as with supplements, so I decided to write this Vielight Review.

The Science behind Vielight Intranasal Light Therapy

Girl Using Vielight Intranasal Light Therapy

Light energy has beneficial effects on red blood cell structure, enhancing their ability to take up oxygen, while also improving blood flow and reducing blood pressure.

Red light in the 663–655nm (nanometer) wavelength range and infrared at 810nm are ideal for photobiomodulation therapy.

This is because these wavelengths are well absorbed by blood and tissue. Also, red and infrared light have a high enough energy intensity to produce biological effects, but not so high as to create excessive heat or damage in the body tissues, such as UV light can.

Light of specific colors and intensities stimulates the mitochondria (energy factories) of cells, including red and white blood cells, thereby increasing cellular energy and enhancing immune system function.

Specifically, cytochrome c oxidase, the last enzyme in the respiratory electron transport chain of mitochondria, is able to absorb red and infrared light and use this energy for the synthesis of adenosine triphosphate (ATP). This ATP is the primary transporter of chemical energy within all the cells of the body.

Mitochondrial Photobiomodulation. A single mitrochondria being illuminated by red or infrared light.
Mitochondria being illuminated by red light

Infrared light (in this case at 810nm) can enter the brain from the nasal cavity or through the skull and stimulate cytochrome c oxidase enzyme activity and oxygen consumption by nerve cells, thus leading to increased energy and improved function and healing capacity.

It takes the heart less than one minute to pump blood to every cell in the body. In fact, the entire six quarts or so of blood can fully circulate throughout the body at least three times within that minute.

Therefore, illuminating the blood in the nasal region, where there is a large surface area of fine blood capillaries are near the surface (there are more capillaries per square centimeter just below the surface membrane in the nasal cavity than just about anywhere in the body.), soon illuminates the entire blood supply as it is pumped around the body. The therapy also influences the lymphatic system.

Benefits of Photobiomodulation Therapy With Vielight

One major advantage of Vielight Intranasal and Transcranial Light Therapy is that there is are no foreign substances introduced into the body, no needles, no pills to swallow and no side effects.

Intranasal and Transcranial light therapy is supported by scientific studies and it is complementary to dietary supplements and medications. After you invest in one you have no ongoing costs , unlike you do with supplements or other treatments.

Vielight Devices are high quality, durable, and portable. The Vielight Intranasal Devices are pocket-sized and run on a single AA battery for up to three months. I use a rechargeable battery, which is more environmentally friendly and saves money. If you use rechargeable batteries you just need a tiny bit of power to recharge them every few weeks.

Many people who have used intranasal light therapy have reported experiencing fast improvements from the following conditions: headaches, migraines, facial pain, sinus congestion, blurred vision caused by poor circulation, some bacterial and viral infections and pain.

Many have found relief, even overnight, from chronic fatigue and sleep disorders. And within two weeks many report improvements from high blood sugar, high blood pressure, impaired circulation, high LDL cholesterol, traumatic brain injury, mild cognitive impairment, chronic low immunity, depression, nasal polyps, some autoimmune illnesses, epilepsy and more.

This is based on studies, observations and feedback, using the device for 25 minutes once a day. Observed improvements don’t necessarily mean a cure and improvements may not always be significant, but some users have reported dramatic improvements where other treatments have not succeeded.

Photobiomodulation research has shown many beneficial physiological effects, including:
  • Activates cytochrome c oxidase (COX) to produce more ATP in the mitochondria (cells’ powerhouses).
  • Reduces inflammation through production of anti-inflammatory cytokines.
  • Improves sleep quality.
  • Cognitive enhancement — improved memory, learning ability and reaction time.
  • Up-regulation of cytochrome oxidase activity leads to neuroprotective effects, self-repair & enhanced neuronal function.
  • Creates mild oxidants (reactive oxygen species or ROS) leading to gene transcription, cellular repair and healing.
  • Releases nitric oxide from hypoxic/impaired cells back into the system. Nitric oxide is used for cellular communication and it also helps dilate the blood vessels and improve blood circulation.
  • Accelerates wound healing.
  • Stimulates the mitochondria of white blood cells, potentially leading to improved immune function.
  • Improves red blood cell structure, thus reducing cell clumping and augmenting the oxygenation capacity of your circulatory system.

Vielight Devices — Two Systemic, Four for Brain

Vielight devices combine solid state technology with diodes (LEDs) built from transparent high impact polycarbonate to ensure quality and durability, making them into a lifetime investment. All models come with a one year warranty and a six month, 80% money-back guarantee.

Systemic Photobiomodulation

Vielight 633 Red

Vielight 633 Red

The Vielight 633 Red is a popular option and it is the lowest-priced Vielight device available. Unlike the 655, it is a non-laser device, so it can be sold in the US.

This is a non-laser intranasal light therapy device. The basic specifications include an optimally engineered diode (LED) emitting photons within the visible red spectrum (633 nm) wavelength powered by a calculated dosage of energy to irradiate the capillary-rich nasal cavity.

Vielight 655 Prime

Vielight 655 Prime

This is the laser equivalent of the Vielight 633 Red device. It is the one that I own and that prompted me to write this Vielight Review.

The Vielight 655 utilizes a low-level (or “cold”) laser diode to release coherent light in the visible red spectrum (655 nm), powered by a calculated dosage of energy to irradiate the capillary-rich nasal cavity.

The energy generated by this device is lower than the 633 Red resulting in a more power-efficient design. There is slightly more research behind laser photobiomodulation than with LEDs and they are potentially slightly more effective, but there isn’t a big difference.

CAUTION: Because it is a laser, users shouldn’t look directly at the light as it may cause eye damage. NOTE: This item can only be shipped to countries outside of the United States due to FDA regulations on laser-based wellness devices.

Brain Photoneuromodulation

Vielight 810 Infrared (Brain)

Vielight 810 Infrared (Brain)

The Vielight 810 is a non-laser intranasal light therapy model. Engineered for gentle brain stimulation, this device complements the systemic effects of the Vielight 633 Red and Vielight 655 Prime. Near-infrared photons at 810nm are invisible to the naked eye.

The near infrared light passes through the intranasal channel into the deep ventral areas of the brain. Neurons are well-suited for photobiomodulation because they contain mitochondria.

Before and after QEEG (Quantitative electroencephalograph) images show the Vielight 810 inducing restorative activity in the brain after a 25-minute session.

Sleepiness is a common side effect of using this device due to the 10 Hz pulse rate of the beam correlating with alpha brain waves and because of neuronal stimulation.

Wearing Vielight Neuro Alpha or Gamma while studying

Vielight Neuro Alpha (Brain)

The Vielight Neuro Alpha, Neuro Gamma and Neuro Duo combine intranasal with transcranial infrared LEDs for a much more powerful effect on different regions of the brain.

These Vielight Devices are a significant upgrade from the original Neuro Alpha, with triple the power density and an improved form to more comfortably fit different head shapes and sizes.

Vielight Neuro Alpha

The main aim of these three devices is to improve mental acuity and cognition without negative side effects. Not more than one 20 minute auto-timed session is required every second day. The Neuro Alpha, Neuro Gamma and Neuro Duo have built-in rechargeable batteries.

The transcranial LEDs specifically target the Default Mode Network (DMN) regions of the brain. These areas are associated with more introspective functions, such as memory and self-awareness when the brain is more at rest.

Vielight Neuro X-Plus mounted on head and in nose

Evidence shows that people with Alzheimer’s and autism have disruptions in the DMN areas. Meanwhile the intranasal applicator irradiates the deeper zones on the underside of the brain.

The infrared lights have a 10 Hz pulse rate, consistent with the pulse rate of the Vielight 810. This correlates with alpha brain wave entrainment and efficient cellular light absorption. There is currently clinical data backing up the efficacy of the Neuro Alpha.

Vielight Neuro Gamma

Vielight Neuro Gamma (Brain)

The Vielight Neuro Gamma is identical to the Neuro Alpha in all respects except for the pulse rate, which is 40 Hz.

This correlates to the low end of the Gamma brainwave region, giving a stronger effect on memory enhancement. The Neuro Gamma is still undergoing a number of clinical trials.

Note: Near-infrared photons are nearly invisible to the naked eye, making the beam appear much dimmer than it actually is (175 mW/cm2 per diode).

Vielight Neuro Duo (Brain)

Vielight Neuro Duo (Brain)

As you might have guessed from the name, the Vielight Neuro Duo combines two transcranial photobiomodulation (PBM) devices, the Neuro Alpha and the Neuro Gamma, along with an intranasal applicator, into one unit.

You can now enjoy the option of 10 Hz and 40 Hz pulsed PBM via two separate control units with one common transcranial headset.

This is a very economical package because you effectively get two units for only 35% more than the price of one. You then get the complimentary brain benefits of both.

Vielight Neuro X Plus

Vielight X-Plus

The Vielight X-Plus was initially designed as an add-on for the Neuro, and it enables delivery of photobiomodulation (PBM) to areas of the brain not already covered by other Vielight devices.

It comes with powerful 810 nm infrared LEDs attached to a flexible stainless steel band, to deliver near infrared (NIR) light to various brain areas (primarily at the back of the head), as well as to other areas of the body if needed.

The X-Plus also comes with its own 633 nm intranasal applicator, so you can get systemic photobiomodulation therapy (PBM) at the same time as near infrared brain PBM therapy.

The X-Plus is less than half the price of the other transcranial Neuro devices and it represents a good step up from the Vielight Intranasal devices if you can’t afford the more expensive Vielight Neuro devices.

You can use the Vielight 633, 655 or 810 intranasal devices once or twice daily for 25 minutes each, but don’t add in extra treatments in a day to compensate for any missed treatments. When doing two sessions a day you should have a break of at least six hours between treatments.

The small unit can clip onto a pocket or belt, and each treatment is timed for 25 minutes. You just press the button to start and after 25 minutes the Vielight beeps three times and shuts off. I am having a session right now as I finish writing this review.

The Vielight Neuro Alpha, Neuro Gamma and Neuro Duo transcranial devices can be used for one 20 minutes session every second day. More than that is not recommended as they are quite powerful.

The Vielight can be used by only one person at a time, but you can buy additional nose pieces for the intranasal devices so that each person can have their own for their individual treatments.

The nose clip comes with a rubber sleeve on the clip to grip your nose for when you are moving about or exercising, but I find it much more comfortable to remove the rubber grip, which tends to press quite firmly on the nose, and it still stays comfortably in place while sitting or walking.

I also like to swap over to the other nostril halfway through, but be careful doing this if you are using the 655 nm laser model! I close my eyes when moving it over and I’m careful not to point it directly towards my eyes.

Probably the best time of day to use the Vielight devices is afternoon or early evening. Red light exposure produces a shift in cell redox potential in the direction of greater oxidation and increased Reactive Oxygen Species (ROS) generation.

Therefore, it is better to do this therapy later in the day since the body also produces ROS at night-time to clean up old and impaired cells and destroy foreign invaders. If you take any anti-oxidant supplements, these should be taken in the morning anyway — they are likely to interfere with the Vielight’s mechanism of action if taken too close to treatment time.

Using the Vielight just before sleep may be fine, but there is a chance that the melatonin produced by the body at night could also inhibit the effectiveness of the Vielight therapy since it is a powerful anti-oxidant.


Personally, I can attest to improved immunity since I started using the Vielight 655. It is one of the main components of my healing regime along with my SaunaSpace Luminati near-infrared sauna. That is why I am happy to promote these devices in this Vielight review so that others can also feel the benefits.

Vielight have an 80% refund policy, valid for 6 months from the time of purchase, if you find that devices do not help you. This only applies to direct purchases from The return policy is reassuring because not everybody notices or feels any benefits, although there are many remarkable and positive Vielight Reviews to be found online, on Amazon for example.

    Are there any concerns about using the 633 if there is a benign brain tumor present. Will it affect its potential growth?

    • Tim

      Hi Cynthia,

      Thanks for your question. I don’t know of any studies specifically related to the effect on benign brain tumors, but in relation to stimulation of cancer cell growth, the 633nm Vielight appears to be safe, based of photobiomodulation studies. There have been a handful of studies that showed stimulation of cancer cell growth in cell cultures and in lab animals treated with photobiomodulation, but most other studies and human clinical results on the other hand are overall very positive.

      So, while there has been some concern in the past that photobiomodulation therapies, like the Vielight, might stimulate cancer cell growth, overall most of the research and clinical evidence shows encouraging results, including promoting cancer cell death (apoptosis), boosting the immune system, enhancing the effect of other treatments and reducing their side effects, and increasing cellular energy (mitochondrial activity). If you are interested, a good summary is provided by this research paper:

      There have been a number of studies showing quite beneficial results in treating a wide range of brain disorders using photobiomodulation. Maybe it isn’t relevant for what you need, but I thought I’d mention it since you asked about using the Vielight with a benign brain tumor. Of course, it’s the 810nm wavelength device that is designed for gentle brain stimulation and healing, whereas the 633nm device that you asked about is more appropriate for immune system stimulation and general well-being. This paper provides a good overview of photobiomodulation for the treatment of brain disorders, though it is quite technical:

      Based on the research so far, I think you would probably be quite safe to use the 633nm Vielight, but I cannot say definitively that there is no risk. As with all things to do with medical advice, I am not a doctor and I am not qualified to make a recommendation for you, but I hope at that the information I have given might help in your decision. I have been using the Vielight for 6 years now and I haven’t had any recurrence of lymphoma, so at least I can say that it hasn’t stimulated a relapse in my case, and hopefully has contributed to my continued good health.

      Best wishes,

  2. Lucy Aleman

    HiTim: can you tell me, if I buy the Duo, and I use it. Will both the alpha and the gamma run simultaneously? Or can I choose one or the other for a session?

    Thank you,


    • Tim

      Hi Lucy,

      That’s a good question and thanks for asking me.

      With the Neuro Duo you just run one frequency at a time, so the idea is to use alpha one day, then switch to gamma the next day, and alternate like that. Although there is always a spectrum of brainwave frequencies operating in the brain, with certain frequencies dominant at certain times, it would probably be counterproductive to have both the 10 Hz alpha and 40 Hz gamma frequencies on the device running at the same time. I expect that the brain would get confused and not sync to either frequency, or it may choose just one to sync with.

      The good thing about the Duo is that it is like having both the Neuro Alpha and the Neuro Gamma in one convenient unit for a much cheaper price than buying each one separately.

      I hope that helps. Best regards,

    Hello Tim

    Recently my brother had a stroke which caused him to be helpless. On a positive he is well in health and we are trying to get him back on track. Can you advise if the vielight will be useful to aid in recovery.


    • Tim

      Hello Patrick,

      I am sorry to hear about your brother and I wish him a full recovery with your help. I cannot say conclusively that the Vielight will be highly effective in your brother’s case, but it certainly has been shown to be of some benefit in recovery and repair following stroke and brain injuries. The Vielight / Photobiomodulation (PBM) has been shown to have positive effects on reducing inflammation and oxidative stress, as well as promoting neurogenesis; all important elements for stroke recovery. I would say that it is certainly worth a try as an adjunct therapy in addition to other things you are doing. Research so far does demonstrate some promising results, but more clinical studies are needed. For example, this review paper available through Pubmed gives a good summary of the current state of research: Photobiomodulation and the brain: a new paradigm. Since the technology is relatively new, ongoing research and clinical trials will gradually start to paint a clearer picture on its benefits for stroke and traumatic brain injury over the coming years.

      The Vielight Neuro Alpha 810 nm would be the device that I recommend for maximum therapeutic effect in overall brain healing. It is three times more powerful than the Vielight 810 nm intranasal device and combines transcranial stimulation with the intranasal stimulation. However, if you can’t afford that, then go for the Vielight 810nm, which could be used up to twice daily at least six hours apart. On the other hand, for the Vielight Neuro Alpha the user manual only recommends using it every second day, but it might be worth writing and asking them whether that could be increased to daily for a while for maximum therapeutic effect. Or ask your doctor/specialist about it. It would definitely be safest to start off with one treatment every second day though if you get the Neuro Alpha.

      Remember, you can also give it a try and you can return it if you don’t think it is giving any benefit. All Vielight devices come with a six-month satisfaction guarantee for 80% of your money back, if purchased directly from Vielight.

      I hope that helps your decision. I wish your brother all the best in health.

      Best regards,

    Hello Tim
    Can you please help simplify all this for me by identifying the Vielight equipment that will be best for grande mal epilepsy/nocturnal/catamenial epilepsy. I look forward to your response please.

    • Tim

      Hello Oyinda,

      Thank you for asking me this question. It is actually a hard question to answer definitively, because not a lot of research has been done on the effects of photobiomodulation therapy on epilepsy or seizures. Most of the research has been done on Alzheimer’s, Parkinson’s, stroke, depression, mild cognitive impairment and brain injuries, with some beneficial results.

      I would recommend the Vielight 810nm for brain healing and it also has the advantage of the pulsed infrared light at 10 Hz. This frequency is in the alpha brainwave range and this frequency has been shown to be beneficial for epilepsy and for calming the mind. However, caution must be taken when using pulsed lights as it is well known that flashing lights can induce epileptic seizures in some people. Since, the 810nm is in the infrared light range there should be little risk of this occurring. For a more powerful overall therapeutic effect, the Vielight Neuro Alpha is the best option, though this is considerably more expensive. However, in addition, the 655nm could provide some benefit by reducing the release of glutamate, a neuro-exitatory amino acid in the brain, to the rest state, thus calming the epileptic activity. Although this is red light, it is continuous, not pulsed, so it is safe for epilepsy. Overall, I think the first choice is probably the 810nm.

      I hope this helps you a bit. I have to say that it may or may not help improve these conditions, and it shouldn’t do any harm, but since there isn’t much research there is no guarantee that it will help. Since I am not a qualified medical doctor I am just giving you advice based on my own online research. I think it would also be good to check with a doctor or specialist before going ahead with your decision.

      Best wishes!


  5. Melodie Rakes

    I am very interested in the veil light but apprehensive about purchasing.
    Are there any doctors in Marrero, LA where I could get further information

    • Tim

      Hi Melodie,

      Thank you for your question.

      I live in NZ and I don’t know of any doctors in your area. However, you could contact the North American Association for Photobiomodulation Therapy in New York state ( They may know about doctors in your area or give professional advice about the Vielights.

      Remember to choose the Vielight device appropriate to your needs: the 633nm (or 655nm option for those outside the US) for systemic benefits to red blood cells, oxygenation and mitochondrial function, or the 810nm for neurological healing, calming and improving mental acuity and cognition.

      There are also the transcranial devices for enhanced neural wellness and mental clarity (Vielight Neuro Alpha); and improved cognition and memory enhancement (Vielight Neuro Gamma). I haven’t used these two though, so I don’t have personal experience with them, but it sounds like they could be quite effective.

      Best wishes!
