If There’s Just 1 Video You Watch This Week, It Needs to Be This

Fewer outbreaks. Shorter outbreaks. More confidence.

That’s our guarantee.

You’ve tried everything.

Ointments, creams, prescriptions, lifestyle changes, diet changes, and even crossing your fingers 🤞.

Truth be told, those options help a little (maybe not that last one). But at the end of the day the outbreaks still. Won’t. Stop.

Worst of all, your social life is put on hold time after time. It’s like watching your favorite movie with a pause every 10 minutes.

It’s the 21st century and while technological advances are happening seemingly everyday, it still feels like cold sore treatment has been stuck in the 1800s.

So what are you doing here?

Like the thousands who have visited Luminance RED before you, you’re giving it one more shot—crossing your fingers one last time. Will this finally be the solution?

Confidence. Is. Everything. It’s Time to Reclaim It.

In today’s world—with selfies, dating apps, social media, work video calls, and so much more—maintaining confidence is a valuable asset (perhaps the most valuable).

Confidence is also incredibly difficult to have when you’re struggling with outbreaks every few weeks or months, or even when that inevitable itch or tingle crops up.

My name is Ryan Jensen and more than ten years ago I first became aware of this near-constant struggle. At the time I was working for a company that specialized in full-body light therapy, something that even to me sounded too-good-to-be-true—at least initially.

But then I saw the clinical data and I was blown away by just how effective light therapy is for a wide variety of skin conditions, including those caused by viruses (see where I’m going with this?).

What I learned, however, was that no one had used this technology exclusively for lip sores (cold sores and canker sores). But not for lack of effort or lack of science surrounding the issue.

Instead, and I’m sure this will come as no surprise, the reason something like this didn’t already exist was because it was too damn expensive.

Before Luminance RED, you had just a few options:

  1. You could choose to do nothing and suffer through outbreak after outbreak.
  2. You could use ointments, creams, and prescriptions with disappointing results. You could visit your dentist and undergo laser diode treatments that cost $75–200 per visit.
  3. Well, there was another option. You could have purchased your own laser diode equipment for private home use at the low, low cost of $10,000–$25,000.

Ok, so maybe this wasn’t really an option, but you can now see the problem I had to try to solve: how could we scale down this sort of technology without losing effectiveness and while making it affordable?

The answer? Drumroll, please.

We couldn’t.

We couldn’t do it ten years ago. We couldn’t even do it five years ago.

But something truly remarkable happened in the last few years: the output of LED lights increased exponentially while the cost to manufacture them decreased at almost the same rate. In other words, I had my idea a little too early. But the good news is that I was prepared to bring my idea to life now that the technology caught up.

If you continue reading below, I’ll explain how our device works and what it can do for you, your confidence, and your peace of mind.

What Would an Extra 30 60 180 242 Days Between Each Outbreak Mean to You?

Luminance RED harnesses the power of the sun. That sounds dramatic, but let me explain:

Doctore with Lip Device

Just like your skin metabolizes sunlight to make vitamin D, or even nutrients from food, as the 660 nanometer wavelength of light from the Luminance RED device hits your skin, your skin metabolizes that into adenosine triphosphate (ATP)—the building blocks of energy—which allows your body to keep the HSV-1 cold sore virus at bay (even when you’re sick, stressed out, worn out, etc.). Essentially you’re giving your skin cells more energy to improve the speed at which it can heal itself.

In other words, Luminance RED provides a significant jumpstart to your skin’s natural ability to self-heal.

As a result, you can enjoy far fewer outbreaks and shorter outbreaks. In fact, by using Luminance RED 2-3 times per day (with at least 4 hours between treatments), you can have 263 days between outbreaks:


That date you had planned for Saturday that you’d normally have to cancel half the time? Go have fun.

That wedding you RSVP’d to a year ago and had marked on your calendar? The dance floor is all yours.

That video conference call for work? Lights, camera, action. The spotlight is no longer the enemy.

With Luminance RED, you’ll have many more circled dates on your calendar and far fewer canceled plans.

But what happens when you get an outbreak? Using Luminance RED, your time to heal can be cut in half.


Want more data? You can see the clinical research studies here.

To achieve these results was no easy feat. The light emitted from the device must be applied at both the proper wavelength and irradiance. That's exactly why Luminance RED was designed specifically to meet these specifications.

And to ensure you can enjoy these results for a lifetime, we use only the highest quality components and features:

  • A fiber-optic tip (this allows the light to be emitted unobstructed).
  • A visible (red) light, so you always know when the device is working and on or off.
  • Higher power output, which means you don’t need to apply treatment for as long as the cheaply made and less effective devices out there (60 sec vs 3 minutes).
  • A digital countdown timer to remove all guesswork.
  • A rechargeable, high-capacity battery with a charging base to eliminate the need to repeatedly purchase batteries.

30-Day 60-Day 3-Month
6-MONTH Money-Back Guarantee

You’ve tried everything—what’s one more? The difference with us though is that trying Luminance RED is 100% risk-free. If you don’t see results with your Luminance RED device in the first six months of use, send it back for a full refund. We’ll even cover the return shipping.

We’ve seen the data and the ecstatic reviews from our customers. We know you won’t be disappointed. That’s why we’re so confident that we can offer this unprecedented six-month guarantee.

Reclaim Your Confidence.

The Peace of Mind You’re Looking For:
The Luminance RED Is Registered with the FDA

I've used it several times over the last month: once on a full blown sore and twice when I felt the beginning of one. It helped me manage the main sore and completely stopped the formation of the other two.”

- John D.

I began to get a sore the week before my wedding! I was anxious and came across this product after doing some research online. It was fairly pricey and I was a little skeptical, but with the money-back guarantee, I felt pretty good about giving it a try. 

I’m so glad I did! Within 2 days of using the product, my sore was so much better. I can not thank you enough for this product -- it saved my wedding day for sure! I would highly recommend it to anyone because this product works! Thank you so much!!

- Angela S.

I have tried many ointments and medications this summer and recently had my worst outbreak. As soon as I got home and saw that my Luminance RED was delivered, I was so excited and used it three times per day for three days. Now my skin is back to normal! I almost gave up hope, but I’m so happy that I can go out in public again. Thank you so much! 💙💙

- Johnathan S.

Thank you for your help. And yes, your product has been most helpful for me when I start to get a sore. I rarely get outbreaks any more. Great product. Thank you.

- Jack B.

This has been such a miracle worker! My little one was getting sores -- three at a time! This helped in no time. Now when I see one popping up, I do a treatment and it’s so much better. 

- T.

This thing is an answer to prayer. I scoured the internet and ran into this. The reviews were outstanding. I had no problem spending the money. I was desperate. Every time I get a sore, not only is it disgusting, but I can't kiss my wife and that's what hurts me the most. I always get sores from trips because of the stress of traveling coupled with different environments and such. I get them maybe 6 times a year and I hate it.

It came charged and I immediately directed the light on my lip sore. I did treatments 2 times a day for the past 4 days and my sore is now completely gone.

 I am completely floored. And I couldn't be happier. My mind is blown. This is a miracle of modern science. Try this product with confidence. You have nothing to lose.

- Sean O.

I purchased this product because I had two terrible sores toward the back of my mouth. I was in terrible pain and quite desperate. The first day of treatment, I had pain relief. I’m so grateful.

- Tiffany G.

So far, it's stopped two different sores dead in their tracks...one for me and one for my daughter. We are very pleased.  

- Joanna W.

I've had breakouts 2 times a year since I was about 7 years old. I truly have done everything and nothing has ever seemed to work.

The Luminance RED treatment is an absolute game changer. I own multiple small businesses, and because most of my responsibilities are customer-facing, the level of satisfaction and peace of mind this has given me from one solitary use has me giddy like a school boy.

- Joshua F.

Your product does work. I had a sensation of the sore beginning to form and I used Luminance RED for 6 treatments, over a 3 day period. The sore completely disappeared. During the treatments, the sore did not progress either. I believe you have a great product.

- George Z.

If you get lip or mouth sores, you NEED to buy this! You'll have relief in only 60 seconds!!!

- Kay

Having lip sores for the majority of my adulthood, this is a lifesaver! I could not believe the change I saw after one 60 second use! It was incredible. If you are like me and have gone back and forth because of the pricing, JUST BUY IT. I wish I would have years ago because I could have avoided so much stress of hiding my face all the time and not going to events because of it.

It is totally worth the price, and you can see changes right away!

- Kim

I purchased a Luminance RED almost 6 months ago. My daughter has HSV2. She has used it as directed for almost the entire time. We believe it has made a difference. She used to have outbreaks each month longer than she would have clear days. Due to being autoimmune compromised, she has sores that look like deep knife cuts as opposed to blisters. The last few months she now has weeks between outbreaks, instead of days. This is an answer to prayer!

- Carol M.

My fiancé actually got it for me. We were very surprised and very happy at how fast the device was delivered. I’ve been using the device since last Saturday and I have to say it’s quite amazing! The device has not only helped the healing process but it also helped it from spreading. I am so impressed with this device and truly grateful!

- Windy L.

This is amazing to finally have this technology at home! I used to have to go to my dentist when the first tingle of a fever blister would start. Usually from start to finish it takes two weeks to get rid of my fever blisters! Now I’m almost clear after 4 days (3, 60 second sessions every day)!

Thank you so much! Best thing I’ve ever bought!!

- Anna S.

First of all, I don't do reviews! So why am I writing this one? Simply to help others that have challenges with fever blisters. This device worked for me. That said, it is not a one-time miracle. Here's what happened to me. I had 4 fever blisters in various stages of development. My old standby was Abriva. I received Luminance RED on Monday and I used it several times that day. Fever blisters stopped in their tracks by Wednesday pm and completely gone by Friday pm. It stopped an additional blister from forming on Thursday into Friday. Best $$ I've spent in a long time!

- Diego D.

Game changer! I’ve struggled with lip sores for the last five years or so. This last year I got to a point where as soon as one went away, another popped up and my anxiety was through the roof. I even went to a dermatologist and got an antiviral but that didn’t work. I was skeptical when I saw this product but I thought it was worth a shot. Thank God I did. I used it regularly for the first couple months and my sores reduced over time. I’ve gotten to a point where I only use as needed when I think I might get one and it usually stops the sore in its tracks. I would estimate my sores are reduced by 90% if not more. I feel “fixed”. I would definitely recommend it to someone with chronic cold sores b/c it really works.

- Jack

Crying tears of joy! I have been dealing with lip sores for the past 12 years. It's been HORRIBLE. I've had to cancel plans, been upset that they wouldn't go away, and have felt every other negative emotion possible.

I started feeling one come on yesterday, so as always, I swallowed mountains of antiviral medicine and huge lysine pills. It helped so don't get me wrong, but I could still tell that it was there and moreover, was SUPER painful. I have been holding off of ordering this because of the price. I wish I bough this SOOOO much sooner.

I ordered it yesterday and started using it as soon as I got it. WITHIN TWO HOURS, both (yes, I had two) sores were 90% gone. This is after only ONE 60 second round. I feel sooo much better about it already

If you are like me, and have been having this happen to you after years of canceled plans and embarrassments, PLEASE DO NOT HESITATE like I did. Give yourself the freedom of getting rid of these things once and for all.

Clinical Studies: Phototherapy and Cold Sores

The information provided is for educational purposes only and is not intended to support the safety or effectiveness of Luminance Medical’s devices, or diagnose, treat, cure, or prevent any disease. It's not a substitute for a consultation with your healthcare provider and should not be construed as medical advice. The clinical studies presented below were conducted with devices that deliver the same or similar light wavelengths and irradiance as the Luminance RED.


Clinical Data shows that light treatment can help to heal faster, stop pain and reduce future outbreaks.

Short on time? Watch this short video that summarizes of some of the key findings resulting from recent clinical trials. 

Whether you’re suffering from a painful cold sore or you’re determined to prevent your next HSV-1 outbreak from occurring, you don’t want to spend your time and money on treatments that provide temporary or unreliable results. 

The efficacy of the Luminance RED treatment has been proven in numerous clinical studies, so you can trust that two minutes of Luminance RED therapy a day will reduce healing time and decrease your risk of future outbreaks.  

Luminance RED - Cold Sore Study - Reduction in Outbreaks

Low-Intensity Laser Therapy is an Effective Treatment for Recurrent Herpes Simplex Infection

In this study, researchers selected a group of participants who not only had HSV-1, but had a “recurrent infection,” defined as having at least one herpes attack per month for more than 6 months, independent of any known triggering mechanism such as fever, sun exposure, or menstruation.

The results found that patients who received treatment averaged 37.5 weeks (263 days) before their next cold sore episode, whereas those who did not receive treatment averaged 3 weeks (21 days).

What caused the treatment to have such a big impact?

When assessing why treatment had such a substantial impact on recurrence, an indirect effect of LLLT on cellular and humoral components of the immune system involved in antiviral responses rather than a direct virus-inactivating effect was proposed.

This means that the treatment is suggested to actually strengthen the immune function against the HSV-1 virus, which prevents future outbreaks from reoccurring.

Luminance RED - Cold Sore Treatment - Reduction in Healing Time

Comparing the Effect of Diode Laser Against Acyclovir Cream for the Treatment of Herpes Labialis

In this placebo-controlled study, researchers found that patients who received treatment had a 49% reduction in time to heal compared to those who had no treatment. The treatment group took an average time to heal of 2.2 days while the non-treatment group took 4.3 days. 

The Effect of Low-Level Light Treatment on (Cold Sores)

Low-level laser light at 30-second exposures from a laser light pen was used in this clinical research study to investigate the healing rates of cold sores. Researchers found that light therapy increased the healing rates of cold sore ulcers in 69% of patients. 

In addition to accelerating healing, light therapy reduced 88% of painful cold sore lesions within two days. This was up to five times faster than the untreated control group, which took five to ten days to experience pain relief. 

Overall, this study concluded that treatment of cold sore lesions using low-level laser exposure in the form of light is an effective and affordable way to treat the herpes simplex virus. 

These well-constructed clinical trials clearly demonstrate the efficacy of treating and preventing cold sore outbreaks with light therapy.

However, the light must be applied at both the proper wavelength and irradiance to achieve these results. That's exactly why Luminance RED was designed specifically to meet these specifications.

When It Comes to Your Health, Quality Matters Most

The Luminance RED Lip Sore Treatment Device was the first product of its kind on the market. But being first comes with great expectations—after all, first impressions are everything. So if we were going to spend the hundreds thousands of engineering and research hours to develop a device like this, then we had to do it the right way.

That meant revolutionizing the way we think about lip sore treatment. We shouldn’t have to repeatedly spend $20 on a tube of messy cream or ointment. We shouldn’t have to sheepishly visit the dentist after every outbreak to get $75–$200 laser treatments. And we shouldn’t have to cross our fingers and just hope that we don't get a cold sore outbreak before our next date, wedding, work conference, and so on.

In short, our goal was to make lip sore treatment:

✓ Affordable
✓ Able to stop a cold sore right after it starts
✓ Simple to do
✓ Able to prevent future outbreaks
✓ Confidence boosting
✓ And most importantly, private (what a refreshing word to see)

We Wanted to Do This 5, Even 10 Years Ago

Before the Luminance RED Lip Sore Treatment Device was released in 2018, the only options were creams, ointments, prescriptions, and laser treatments at the dentist. None of these options were preventive, 100% private, or cheap in the long run.

We were aware of this more than five years ago, and we had an idea: what if we could scale down the laser treatment devices that dentist offices had and allow people to use them within the comfort of their own homes?

As we explored this concept, we realized our idea was ahead of where technology was at the time. LED output wasn’t strong enough and the cost to manufacture them was astronomically high. This is why those devices in the dentist offices were $10,000–$25,000.

We had to put our idea on pause and hope technology would catch up.

Fortunately, something remarkable happened by 2018. LED output had increased exponentially while the cost to manufacture LEDs decreased at almost the same rate. This meant we could bring our idea to life and, instead of $10,000–$25,000, take it to the market for $349. Plus, since the Luminance RED Lip Sore Treatment Device is a lifetime solution, it’s significantly cheaper than creams, ointments, and medications in the long run.

Unmatched Quality

We didn’t just want our device to be the first. We wanted it to be the undeniable best for when cheap, unreliable knockoffs would decide to flood the market (and they always do).

To accomplish this, we made sure to get the device registered with the FDA as a class II medical device (ILY) and manufacture it in a fully compliant, FDA-registered facility whose certifications exceed the minimum requirements.

Additionally, we knew we had to use top-of-the-line parts. The Luminance RED Lip Sore Treatment Device features:

  • A fiber-optic tip.
  • A rechargeable, high-capacity battery.
  • A digital countdown timer to remove all guesswork.
  • A charging base to eliminate the need to repeatedly purchase batteries.
  • A visible (red) light, so you always know when the device is working and on or off.
  • And higher power output, which means you don’t need to apply treatment for as long as those cheaply made and less effective devices out there (60 sec vs 3 minutes).
