Red Light Therapy for Cold Sores

Between 50 and 80 percent of American adults deal with cold sores.

Cold sores are highly common, but there’s still a lot of confusion about the most effective ways to address them. If you’re looking for a different treatment option besides over-the-counter medications, consider giving red light therapy a try.

Don’t know what red light therapy is or how it works for cold sores? Keep reading. Explained below is everything you need to know about the benefits of red light therapy for cold sores.

What Is a Cold Sore?

A cold sore is a symptom of a viral infection. Herpes simplex virus type 1 (or HSV-1) is the most common cause, but herpes simplex virus type 2 (or HSV-2) can cause cold sores as well.

Cold sores are characterized by tiny blisters on and around the lips. The blisters usually appear in tightly grouped patches and scab over after they break open.

It usually takes between 2 and 3 weeks for cold sores to heal completely. It’s important to note, though, that they are contagious — even when the sores aren’t visible.

Cold sores are spread when people who have them come in close contact with others. For example, if someone has a cold sore and they kiss someone else, that person could also develop a cold sore.

Cold Sore Symptoms

Before developing the blisters that most people associate with cold sores, you may experience an itching, tingling, or burning sensation around the lips. Small, hard, and painful spots may appear before the blisters erupt, too.

It can take quite a while for symptoms to appear after you’ve been exposed to the herpes simplex virus. In some cases, symptoms don’t start for up to 20 days.

When you experience your first cold sore outbreak, you might develop other, more severe symptoms. These include a fever, gum pain, a sore throat, headaches, muscle aches, or swollen lymph nodes.

Can Cold Sores Be Cured?

Because they are a symptom of a viral infection, cold sores cannot be cured completely. Once you develop them, the herpes virus will continue to lie dormant in your nerve cells.

The recurrence of cold sores can result from a variety of issues, such as stress, hormonal changes, changes in your immune system, or the development of another viral infection or illness.

 You might not be able to prevent cold sores from coming back altogether, but you can manage them and lessen their severity using various methods. This is where red light therapy can come in handy.

What Is Red Light Therapy?

Red light therapy is a popular treatment typically used for skin conditions like acne, wrinkles, and age spots. It exposes the skin to low wavelength red light, which acts on the mitochondria of the cells.

The mitochondria are the powerhouse of the cells and generate energy that powers various biochemical reactions. When cells have more energy, they can function more efficiently, repair the skin, and generate new cell growth. 

Red light therapy has been shown to offer a variety of benefits, including the following:

• Stimulating collagen production
• Increasing blood circulation to the body’s tissues
• Reducing inflammation in cells

In addition to addressing skin conditions, some people have also seen positive results from red light therapy when it comes to reducing stress, minimizing joint pain, and improving hair growth.

Benefits of Red Light Therapy for Cold Sores

When you’re dealing with cold sores, exposing the skin around the mouth to low wavelength red light can be very beneficial. Some reasons to consider adding it to your wellness routine include:

Faster Healing

Because red light stimulates the mitochondria, using a red light therapy device helps to speed up the healing process. This means your cold sores will likely go away faster after they first show up. They may be less painful while they’re present as well.

Reduced Scarring

Most people don’t develop scars after they experience cold sores. However, if you have a habit of picking at your blisters or peeling back scabs as they form, your chances of scarring are greater.

Red light therapy can reduce the likelihood of this happening and keep your skin blemish-free.

Stronger Immune System

As we mentioned above, developing another illness or virus can increase your chances of having a cold sore flare-up. This is why you need to support your immune system as much as possible.

Red light therapy can reduce inflammation and strengthen the immune system, which makes it easier for your body to fight off infections.

Reduced Stress

Stress can also trigger cold sore flare-ups.

Many people find that adding red light therapy to their wellness routine can help them manage stress and feel calmer throughout the day. As a result, consistently using a red light therapy device may make it easier for you to avoid cold sores in the future.

How to Use Red Light Therapy for Cold Sores

If you’re interested in using a red light therapy device to heal your cold sores faster, here are some tips that can help: 

• Buy your own device: Investing in your own red light therapy device saves you from having to drive to and from a medspa or dermatologist’s office several times per week.
• Use it consistently: Daily exposure to red light is best for managing cold sores and other conditions. If you can’t use your device daily, at least aim for several uses per week.
• A little goes a long way: You don’t have to spend hours in front of a red light therapy device to see results. A few minutes per day is usually sufficient.

Be sure to monitor your symptoms, too. Tracking your symptoms makes it easier to see how your cold sores change over time (and how quickly they come back). This can help you see whether or not red light therapy is working for you.
