Cold Sore Laser Treatment: Stop an Outbreak Before it Starts

If you suffer from recurring cold sore outbreaks, it may seem that nothing you try stops them from frequently coming back. Creams, home remedies, and avoiding your known triggers may work for a little while, but it often doesn’t take long for those troublesome fever blisters to suddenly reappear. Because there is no permanent cure for the Herpes Simplex Virus (HSV), the virus that causes cold sores, recurrent sores have historically been tough to prevent. However, clinical data shows that recent advancements in cold sore laser treatment can drastically reduce the frequency at which you experience cold sore outbreaks.

Let’s dive a bit deeper into how cold sore laser treatment, also known as photobiomodulation or low level laser therapy, can be conducted at home to help keep your cold sores at bay.

How Does Cold Sore Laser Treatment Prevent Cold Sores?

According to clinical data, the science behind photobiomodulation is sound. In short, cold sore laser treatment provides your immune cells with the energy they need to combat HSV-1 quickly and more effectively. When you apply six joules of red-light energy to areas where you commonly experience cold sore outbreaks, you “charge” your cells with extra adenosine triphosphate (ATP). ATP is cellular energy, and when you provide your immune cells with this natural boost, they can work harder to prevent the cold sore virus from replicating.

Essentially, you use photobiomodulation therapy to naturally strengthen your body’s immune defenses.

Using Cold Sore Laser Treatment at Home

In its earliest days, cold sore laser treatment required specialized technology found primarily in laboratories and doctor’s offices. It often wasn’t practical or affordable to seek these tools out, even if it offered the most effective treatment to heal and prevent cold sores. Today, thanks to several technological advancements, you no longer need to make a special trip to the doctor. You can treat yourself at home by using the Luminance RED.

The Luminance RED is a safe, easy-to-use device that takes the laser technology from the laboratory and places it in the palm of your hand. The device utilizes a powerful LED red light to provide a photobiomodulation treatment comparable to what you would receive in a doctor's office. Every 60-second treatment session applies the roughly six joules of light energy your cells need to supercharge their fight against HSV-1.

We recommend using this treatment two to three times a week on the areas where you commonly experience cold sore outbreaks. If you want to administer your cold sore laser treatment more frequently, you can safely do so. However, there currently isn’t much clinical data that demonstrates that using the Luminance RED more than two to three times a week offers additional protection against outbreaks.


The Luminance RED’s 60-second, two to three times per week treatment plan offers effective protection to lengthen the time between cold sore outbreaks. Clinical studies show that low level laser therapy can increase the time between outbreaks from an average of three weeks when left untreated, to 263 days with treatment. When you regularly charge your cells with additional ATP, they have more energy to continuously push back against HSV-1. As a result, the virus cannot replicate as easily, and cold sores struggle to form.

If you experience a particularly aggressive outbreak, and a cold sore does happen to form, continue to use the Luminance RED. Other studies demonstrate that cold sore laser treatment can reduce quickly pain and help the cold sore heal more quickly.
