Laser therapy is an effective, inexpensive, simple, and comfortable way to enhance healing of the cold sores and prevent the formation of new sores. Many people are not aware of this and they tend to leave the cold sore to take its course and heal on its own. Using light-emitting diodes is a safe and non–invasive way to eliminate cold sores immediately after they show signs of popping up.
While there are many red-light therapy devices, only specific ones will work for cold sores. Using a red light therapy wand, with wavelengths of 630nm to 850 nm may be ideal in the treatment of cold sores. The best red light therapy on cold sores may help reduce inflammation, enhance wound healing, and repair damaged tissues. In this article, we have provided the important information you may need on the treatment of cold sores using red light therapy devices.
Can Red Light Therapy Help with Cold Sores?
As our content, The Ultimate Guide to Red-Light Therapy details, light therapy, as a drug-free, painless, non-invasive, and effective treatment technology, has gained popularity over the years.
Red light therapy uses wavelengths of 630nm to penetrate the skin to treat various conditions, including pain and inflammation, arthritic pain, muscle soreness, acne, hyperpigmentation, and cold sores. Some red light therapy devices combine the power of red and infrared light to deliver faster results.
Clinical Trials support that light therapy wands may use red light of wavelength 630nm and infrared light of wavelength 850nm to effectively relieve pain and inflammation and promote repair of damaged tissue. These two wavelengths have therapeutic effects on different layers of the skin, as red light works on the top layer, while infrared light deeply penetrates the skin. Using red light therapy wands is an effective and convenient way to deal with ulcers and cold sores inside the mouth. Red light therapy is a non-invasive and drug-free method that works to reduce healing time and prevent the pop-up of cold sore every time. All you have to do is hold the device over your mouth for three minutes every day.
According to research done by Andreia La Selva MD, Renata Matalon PhD, et al and published in the Medicine Journal, cold sores are a painful and self-limiting disease that causes social restraint and discomfort. The study further supports that the use of photodynamic laser therapy is a therapeutic option in the treatment and management of cold sores. Light therapy has many advantages, including shortening the healing duration of the lesion.
An article by Diana Schoutsen in the Rouge Journal agrees that red light therapy for herpes treatment is effective such as cold sores. red light therapy treatment combines red and infrared light to help speed up wound healing, reduce pain and inflammation, and reduce viral shedding. The study further reveals that red light therapy may help reduce the severity of herpes symptoms.
How Does Red Light Therapy Work for Cold Sores?
Red light therapy is a non-invasive, promising, and effective treatment for chronic problems that keep on recurring, such as oral herpes as it, helps reduce the severity of the symptoms and address the factors that cause the condition.

However, it is important to know that treatment will not cure the disease, but only shorten the duration of the outbreaks and reduce the intensity of the symptoms.
Using red light therapy for cold sores at home works to reduce pain and inflammation caused by cold sores, enhance wound healing, and prevent future breakouts. The red light therapy device uses light-emitting diodes to work on the tissues and target the virus causing the cold sore to appear. Light therapy breaks down the proteins of the virus to prevent the cold sore from progressing any further. If the cold sore has progressed and is filled with fluid, the red-light therapy device works to reduce pain and inflammation and lessen the duration and severity of the sore.

Using light therapy for three minutes twice or thrice every day may enhance faster healing.
One treatment session of about 3 to 4 minutes every day should be enough to address a cold sore and prevent recurring. According to the Journal of Investigative Dermatology, herpes simplex virus is a common recurrent disease and it may be effectively addressed using low-level laser treatment.
What Do Scientific Studies Say About Red-Light Therapy And Cold Sores?
- In a pilot study to determine the effectiveness of laser therapy on herpes zoster, 28 Korean patients with acute herpes zoster were selected and used. The patients received light therapy treatment of 850nm. The results showed that LED treatment helped enhance wound healing and reduce pain.
- A publication in the Photomedicine and Laser Surgery journal concluded that treatment of herpes labialis with photodynamic therapy helped reduce wound healing time and reduce the frequency of recurrence. The study further claims that laser therapy provided comfort for the patients without any side effects.
- According to research done by Dennis Carvalho, Helena Lucia, et al and published in the Revista da Sociedad Brasileira de Medicina Tropical journal, using laser therapy has been shown to deliver long-term results in the treatment of recurrent herpes simplex infections.
