My son has struggled with extremely painful mouth sores - usually getting anywhere from 2-5 in his mouth at a time. Usually they heal over 5-10 days depending on how large they are. We've tried MANY supplements, mouth washes, topical treatments, etc. The laser is dramatically reducing the pain level for him. We will continue treating his sores with the luminance red and are grateful to find relief!

My husband purchased the Cankerclear for mouth sores that I have battled for years. After years of going to the dentist and having them burned off with sodium nitrate, my dentist retired and the new dentist that I see doesn’t offer this service or laser treatments. I love the product—it drastically reduced my pain and helped with the healing.

I get severe canker sores with the slightest bit of trauma, have a high-stress life, and an iron deficiency anemia. I have been dealing with pain and discomfort for the past year.

I started using it and saw the healing process improve within the next 12 hours and then made a full recovery 3-4 days after using it.

My little girl got a mouth sore recently and it worked really well to clear that up, too. I was nervous that this device was a bit of a gimmick, but now I'm convinced it works really well.

honestly, canker sores were ruining my life, every spicy meal was off-limits. then I tried this laser, and it’s like a whole new world. pain vanished super quick, healing was fast fast. now I'm back enjoying my fave foods, no stress.

For those of us that suffer from painful mouth sores, this is life-changing. I know that sounds dramatic, but it really does work, especially if you start using it the minute you feel one starting. My recent mouth sore was already fully formed by the time I got the device, but I imagine you would get the same result if you catch those quickly as well. It's expensive, but so is going to the dentist to get laser treatments, and not all dentists offer the service.

- Gina

so here’s the tea, my doc was all out of ideas for my canker sores, but then I found this laser. I was like, is this for real? And yes, it totally is. Pain vanished like a ghost, sores healed up like magic. Now I'm all smiles, eating all the spicy goodness I want. This laser's the boss.

I feel it is very important to share our experience with Luminance RED. My husband suffered from several very large sores in his mouth for four terrible months. Eating, speaking, and sleeping were extremely difficult because of excruciating pain. After trying several failed treatments and seeing many doctors, I purchased the product out of desperation. Amazingly, within two days, we saw significant improvement and I am happy to report that after continued use for two weeks, his mouth is back to normal. It was literally a lifesaver.

I have gotten odd sores on my tongue and gums forever. This light works! It is amazing on large mouth sores! Takes pain away and helps with healing. I just had a little red spot on my tongue. It wasn’t that painful and I almost didn’t use my light on it, but why suffer? After just 60 seconds with the red light, the pain was gone! 

I am excited to help my grandkids with painful mouth sores! I don’t want them having mouth pain with all the great holiday food I’m making! I travel weekly and I actually store my Luminance light in my carry-on suitcase! I’m never leaving town again without it!

I am thrilled with the results using the Luminance Red mouth sore device. The day I started using it, I had a canker sore on the inside of my lip that I had bit several times while chewing. I treated it with the device, and after just a few treatments, it felt much less swollen, less painful, and I could tell that it had started to heal. Within two days, it was not at all puffy anymore. In the past, I would struggle waiting for this type of sore to heal. However, after using the Luminance, the healing process was noticeably quicker. The almost immediate reduction in swelling allowed me to eat without biting the area and the pain improved very quickly. I am excited to use this product in the future for myself and the rest of my family!

I learned about this product from a friend. She said after one use, her mouth sore disappeared so I couldn't wait to get mine and try it out. When it arrived, I did have a small sore on my cheek. I used it for 60 seconds and then another 60 seconds later on. I woke up today and it is gone! This product is life-changing for those of us who suffer with these painful sores. I highly recommend it.

- Deanne S.

The device arrived at the peak of an outbreak with a 0.7mm sore on my inner lip, a smaller sore on my gum, and a smaller sore on the side of my tongue. It was extremely uncomfortable to eat and talk.

The smaller sores barely bothered me after 1 day. After 2 days, they were no longer painful even if I touched them directly.

After 1 day, the larger sore felt slightly less painful and did not grow; I could talk more comfortably. After 3 days the larger sore was barely noticeable.

Yes!! I am happy; thank you. Me and my son both have these mouth sores. It’s so frustrating to see my son hurt from these sores. So, thank you b/c it is helping.

I bit my lip last Thursday. Usually when I get cuts on my mouth, they immediately become a canker sore. That night I started the light therapy. It is now almost fully healed. I can't believe it but it happened. You guys might have found a cure. If this is true I want to quit my job and come work for you guys. I have been getting mouth sores since I was 18. Some of them were very very painful.

- Michael F.

OMG I love this product. I have suffered from ulcers my whole life. I’ve never been able to find anything that works like this product. I have been ulcer free for the last 3 days after using this to treat 2 full-blown ulcers and 3 that were just beginning! I am so amazed how well it has worked and how easy it is to use. I was very skeptical and only made the purchase because of your money back guarantee. If not for that, I wouldn’t have made the purchase.

had to skip tacos & all cuz of canker sores, not cool. tried this laser & it's lit. pain's gone, healing's quick

The Luminance RED light 100% WORKS for mouth sores. I wanted to use it several times before reviewing it and I also wanted to make sure I used it on a sore I knew would be a bad one without the use of the light.

I’ve had it for over a month now and have used it several times on myself and my son. First, it immediately takes away the pain like magic. Works for other cuts in the mouth too. Second, it helps with the healing process exponentially. I’m attaching a picture of a canker sore on days 2 and 3 for my son. On day 1, he told me he had it and it was painful. Used the light twice. Pain immediately gone. Second day, it was painful again in the morning so I hit it twice with the light again. Pain gone and by the end of the day, the redness around the sore was gone. Day 3 it was practically gone and caused no pain and didn’t need to use the light. This was a mouth sore that surely would have lasted 5-6 days and would have been super painful otherwise.

The light is REALLY bright. They say you don’t need eyewear but I bought green glasses on Amazon meant for red light and they work great to cancel out the brightness. I cover my son’s eyes with a cloth as he lays down. The treatment lasts 60 seconds. If the sore is bad, you can do a few treatments each day. The treatment itself is very soothing and the light is so very slightly warm. You hold the light about 1/2 inch away from the sore.

WORTH EVERY PENNY!

This thing really works! I received the Luminance RED device 2 days ago. I had 6 already formed sores in my mouth. 3 of them on my tongue, 1 on my lip, and 2 on my gums. I had been using a numbing topical called Kanka for relief which works for a short time and basically numbs your whole mouth. I had been doing that for about 2-3 days. As soon as I got the Luminance, I used it immediately and all I can say is wow! It did not numb them right away, but about 15 minutes later, they were easily 80% less painful and I have not used or needed the Kanka since then. I was coming home from my daughter's house yesterday afternoon when all of a sudden I felt that tingly sensation of another sore on my bottom lip. As soon as I got home, I treated it with the LR device and never really felt it again. When I got up this morning, I could see it was still there but couldn’t feel it so I treated it one more time and it is like it never happened. This thing is worth every penny!!! Highly recommend to anyone who is suffering from mouth sores or fever blisters. You won’t be disappointed.

I have gotten started with your company's cankersore device, and I gotta tell ya, I'm absolutely blown away. My previous treatment procedure involved a mouthwash that was very concentrated and hurt like hell. It delivered results for a long time, and I was ok with the pain.It just started being less and less effective.  

Enter your product, which I don't even remember how I stumbled onto it, but the 6 month guarantee made a strong impression on me. I was dealing with two sores at the same time, and was excited about the possibility that this thing could provide some hope. After my first use, I was devastatingly disappointed. However, my disappointment stemmed from the fact that it didn't cause any pain, and I was actually kinda hoping that it would hurt, because if it hurt, that would mean it's killing THESE ANNOYING FREAKING THINGS.  

Fast forward a couple hours later, and it hit me that I had forgotten that I even had a mouth sore!  Also, when I brushed my teeth that night, it didn't hurt! The next day, I ate spicy chicken intentionally to see if I could aggravate the sore, and nothing happened!  Man, I am so impressed and so thankful for this. I got a third sore this week, and I have just been smiling non stop at the quality of life improvement that I have ALREADY experienced.

This 100% works!! My daughter gets horrible mouth sores and they're now better in a fraction of the time. Boyfriend used it on a lip sore and it stopped it dead in its tracks! Would buy 100 times over!!

- Raine K.

It’s been a year and a half since I first got my Luminance Red, and I must say I’m impressed how it has worked for my canker sores. 

The product itself it’s well constructed, sturdy and it feels right on the hand. The light is bright but not disturbing to the eyes. I appreciate that is not heavy, making it therefore easy to use for the 2 minute session therapy.

Another great thing about it, is the battery. I have not charged it again since I first received it and it’s still going, which is a great benefit when you travel, as you can choose to take the “pen” only without the charging base.

About the actual results; the first couple of canker sores started healing within 4-5 days (which out of the bat was a huge improvement from the typical week to week an a half period) from the initial treatment. After that, I noticed I was not getting them as often, and when I did get one, they were healing within 2-3 days. Yes! Unheard of!!!

Another reason I love this product so much, is the fact that is painless. Painless!! Anyone who has had canker sores before, knows how awfully painful these are, even with the OTC pain medicine that wears off in 2 mins. So, treating a canker sore painlessly, is an absolute win for me.

I was also really excited when I found out that it can also work for cold sores as I get those as well (yes, lucky me!), however, it didn’t work. The cold sore still grew as if no treatment was applied, compared to the quick response I get if I use Abreva.

Regardless, I still think that the Luminance Red is a five start product and is worth the investment, as I have an effective treatment for cold sores (Abreva), but nothing ever worked for canker sores until I got this product.

So stop doubting and do yourself a favor and invest on the Luminance Red.

You will not regret it!

I have had awful canker sores in spades my entire life . I've gotten them chronically since I was a kid and they get so bad I have had to call in to work because I couldn't speak. Now when I feel once coming on I use this device and I prevent it all together. It's really been life changing in the most literal way. I use to fe helpless. This device is my miracle tool and I keep it with me.

- Jessica D.

This device is awesome! I have had canker sores for many years, and over the past year the frequency and severity had seemed to get a lot worse. I tried many other things to treat and prevent canker sores, but nothing seemed to help. In February 2021, I was battling perhaps my worst canker sore ever, and this was when I got the Luminance Red. It still was a long process to get past this one canker sore, but the Luminance Red helped to lessen the pain. I’m not sure how much it decreased the overall recovery time; however, I eventually got through this canker sore. Here’s where the amazing part came in. After having canker sores at least once a month it seemed, I went 6 months before getting another canker sore. That first canker sore only lasted a few days to a week, and it never got too bad at all.

Canker sores turned eating into a painful task. This laser brought back the joy of meals, pain-free and quickly healed.
