I bit my lip last Thursday. Usually when I get cuts on my mouth, they immediately become canker sores. That same night, I started the light therapy. 

It is now almost fully healed. I can't believe it, but it happened. I may want to quit my job and come work for you guys.

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!!

This thing really works! I received the Luminance RED device 2 days ago. I had 6 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 Luminance RED 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.

My son has struggled with extremely painful mouth sores - usually getting anywhere from 2-5 in his mouth at a time. We've tried MANY supplements, mouth washes, topical treatments, etc. The Luminance RED is dramatically helping and his pain is reduced significantly. We will continue treating the Luminance RED and are grateful to find relief!

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.

How Does It Work?

Photomedicine, or medically-optimized light treatments, have been tested in hundreds of peer-reviewed clinical studies, with overwhelmingly positive results, with little to no observed side effects. Learn more about the emerging research for sores and outbreaks.

The Luminance RED device100% 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. On day 1, my son told me had gotten a mouth sore 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. 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.


Perfect For Easy & Pain-Free Home Use

The Luminance RED is quick and easy to use in the privacy of your home. Treatments are painless and only take a few minutes. The device is sleek, ergonomic, and easily stored for discreet usage.

OMG I love this product. I have suffered from mouth 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. LOVE IT!

Can My Kids Use This Too?

Many peer-reviewed clinical studies have shown light therapy to be safe and efficacious. However, if you have any concerns about using it with children, we recommend consulting with a healthcare professional. Please also note, all treatments with children should be done under adult supervision.

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.

It’s ideal to use the device right away once you feel the tingle and know that a sore is coming. Continue treating affected areas 2-3 times daily, with at least 4 hours between treatment, until the sores have fully healed.

Preventative light treatments may offer benefits for some people. We suggest applying treatment 2-3 times per week to the area where frequent outbreaks occur.
