...literally changed my life!

I have an acidic allergy and have endured painful canker sores since I was a young girl. The suffering over the years has truly been unbearable. After years, and years of trying everything (vitamins, gels, creams, shots, an elimination diet), I finally found something that actually cures canker sores.

The Luminance Red has literally changed my life! The minute I feel a tingle, I immediately put the red light on it and the sore NEVER appears. When I’ve used it on existing sores, I can feel it working instantly and the sores are gone within a day or two.

It’s truly a miracle, and now I won’t ever leave my house without it. The customer service has also been amazing. Trust me, the Luminance Red is a MUST have!



Relief From Chronic Canker Sores

My son has struggled with extremely painful canker/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 Luminance RED is dramatically reducing the healing time and pain level for him. We will continue treating his sores with the Luminance RED and are grateful to find relief!



Works surprisingly well

I purchased this directly from the manufacturer and it works surprisingly well. I had a canker sore starting and it was gone by the next day. I also used on a cold sore that was about to start and it never appeared. I have tried many products over 50 years and this thing really works best. Wish I had this when I was younger.

I used this for reoccurring canker sores. It did take five days for healing. Was very satisfied.

Ends my canker sore in 3 days which normally will keep me in pain for at least 2 weeks.
