Published scientific research suggests medically-optimized wavelengths of light are among the safest, most effective approaches to treating painful skin conditions.
Used by leading salons, spas, dermatologists, dentists and beauty experts around the world, light treatments are also backed by a large base of peer-reviewed clinical studies.
On this page, we’ll explain how light works for skin conditions, and show you how treatments may help manage uncomfortable breakouts in just a few minutes per day with a proven device like the Luminance RED.
Treatments with a high-quality LED device like a Luminance RED are quick, simple, and safe. All you have to do is turn on your device and shine healing wavelengths of light on your treatment area for 60 seconds. The design of the device lets you easily target sores and breakout areas —delivering the light directly to the problem area. Our team of light therapy experts recommend doing this a few times per day for best results.
Light treatments work by stimulating your cells to make more energy and heal more efficiently.  This video breaks down the science behind how light treatments work at a cellular level. Light treatments may lessen pain and inflammation by enhancing blood flow to damaged tissues, and it’s been found in numerous clinical trials to increase the body’s antioxidant defenses as well. 
Quick, simple treatments with a Luminance RED device can have a healing effect on skin conditions like cold sores. And numerous clinical trials have shown positive results when using medically-optimized wavelengths of light for cold sores, canker sores, and genital herpes.
Studies using specific wavelengths of light have shown especially good results for treating common skin conditions like cold sores, canker sores, and genital herpes. A Luminance RED device allows you to quickly and effectively target outbreaks to help reduce pain and improve healing times. They can also help prevent future outbreaks and reduce the frequency of sores.
Clinical research on light treatments and cold sores has shown three major effects: pain relief, faster healing, and the prevention of future cold sore outbreaks.
Reducing pain from cold cores: Recent studies on cold sores have shown significant (and almost immediate) pain reduction after treatment. A 2017 study assessed cold sore pain 24 hours after a treatment. 77% of people treated with specific wavelengths of light experienced less pain within a day, versus just 9% of the placebo group. 
Quicker healing times for cold sores: Left untreated, cold sores can linger for days or even weeks. A study on cold sores found that patients healed twice as fast after treatments. The treatment group took an average of 2.2 days to heal after light treatments, versus 4.3 days without light. 
Preventing cold sore outbreaks: Studies have also shown that light treatments help prevent future cold sore outbreaks. In one study, patients who received treatment went an average of 38 weeks before their next outbreak. Untreated patients only lasted an average of 3 weeks until their next outbreak. That’s 12-13 times longer between outbreaks when patients were treated with wavelengths of light. 
The Luminance RED Cold Sore Treatment Device lets you target your cold sores. It’s rated 4.8/5 stars by customers and comes with a 6-month money-back guarantee.

“I began to get a cold sore a week before my wedding! I was panicked and happen to google “the best treatment for cold sores” and this product came up.
It was a little pricey and I was a little skeptical but with the money back guarantee I felt pretty good about giving it a try.
Medically-optimized wavelengths of light have shown similar positive results for treating painful canker sores. Patients with canker sores have experienced immediate pain relief and overall faster healing times. A systematic review of randomized controlled trials on LED-based light treatments and canker sores showed “significant results” for “pain-level reductions and reduced healing times.” 
Less canker sore pain: In a study on light’s effects on canker sores, researchers discovered very significant reductions in canker sore pain. People whose canker sores were treated with light averaged a 92% reduction in pain, compared to just 1% in the placebo group. 
Faster healing from canker sores: Another canker sore study showed that patients healed three times faster after receiving light treatments.  Without light treatments, people took an average of 8.9 days to heal from a canker sore. With light, it was only 3.1 days. 
The Luminance RED Canker Sore Treatment Device lets you target your canker sores with healing light. This can reduce pain and help you heal faster, and it comes with a 6-month money-back guarantee.

“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."
Herpes outbreaks are unpredictable, and often seem to arise at the worst possible times. Studies on light and genital herpes have shown improved healing times, pain reduction, and a reduction in total outbreaks, giving hope to patients and practitioners. 
Less pain from genital herpes: In one peer-reviewed study, patients who received light treatments for genital herpes averaged an 82% reduction in short-term pain. 
Preventing future herpes outbreaks: The same study also found patients experienced a 67% reduction in viral load (or total amount of the virus present) after treatments. 
The Luminance RED Genital Herpes Treatment Device allows you to treat herpes outbreaks with high-powered wavelengths of light. The device includes a full 6-month money-back guarantee if you aren’t happy with your results.

“My doctor told me to check out the Luminance RED to treat frequent HSV2 genital herpes outbreaks.
He said that it helps to heal more quickly and prevent outbreaks from happening down the road.
I agree and have seen this for myself."
In addition to showing positive clinical results for numerous skin conditions, light treatments have repeatedly been found to be a safe and well-tolerated treatment modality for patients. A 2013 review of existing clinical research on light treatments and skin praised its “noninvasive nature and almost complete absence of side effects.”  Other studies have shown that light is as effective as various oral creams and pharmaceutical drugs, without many of the common risks and side effects associated with those methods.
