Will a Cold Sore Go Away on Its Own?

If you've ever experienced a cold sore, you know how uncomfortable and unsightly it can be. Cold sores, also known as fever blisters, are small, fluid-filled lesions that typically appear on or around your lips. 

These sores come from the herpes simplex virus (HSV-1), and once you’ve contracted the virus, it remains in your body for life. 

The big question on your mind, then, might be, "Will this cold sore go away on its own?" The good news is that a pesky cold sore will eventually go away, but you can do some things to help the healing and lower the frequency of future outbreaks.

At Hines Dermatology Associates, our clinical team has extensive experience treating a full range of skin issues, from relatively simple issues like cold sores to complex or rare skin conditions. 

If you’re dealing with cold sores, take a moment to find out what practical steps you can take to accelerate cold sore recovery. 

The life cycle of a cold core

Cold sores usually follow a predictable cycle that can last up to two weeks. First, you might feel a tingling or itching sensation around your lips. This is the virus reactivating, and within a day or two, a small blister will form. 

Over the next several days, this blister will burst, leaving behind a raw, open sore. Finally, the sore will scab over and heal, typically in 7- 10 days.

During this time, your body’s immune system is working to combat the virus and heal the skin. So, even if you do nothing, the cold sore will still disappear. However, while your body can heal the sore, it doesn't mean the virus is gone — it merely goes dormant and can reactivate once there’s a trigger. 

Can you speed up the healing process?

There are some ways to accelerate the healing process. Here are a few practical strategies:

Over-the-counter creams

Over-the-counter (OTC) creams can be your first line of defense in managing a cold sore outbreak. 

Products containing docosanol or benzyl alcohol are designed to shorten the duration of cold sores, especially if you apply them at the first sign of symptoms. These creams slow the virus's ability to spread, which can help you heal faster and reduce the risk of the sore growing larger or more painful. Consistent use as directed is key to seeing the best results.

Prescription antivirals

If OTC options aren’t giving you the relief you need, prescription antivirals may help. Our clinical team can prescribe medications like acyclovir, valacyclovir, or famciclovir to reduce both the severity and duration of cold sore outbreaks. 

These antivirals target the virus directly, preventing it from replicating and spreading. For individuals who notice frequent outbreaks or severe cold sores, these medications can be a major help in getting you back to your daily life more quickly.

Home remedies and symptom management

In addition to creams and antivirals, you can try several things at home to manage the discomfort of a cold sore. Applying a cold compress can soothe the irritation and reduce swelling, while keeping the area clean prevents secondary infections. 

Using a lip balm to keep the skin moisturized can also prevent the sore from cracking, which may lead to additional pain and a longer healing time. While these remedies won’t cure the cold sore, they can make the healing process more bearable.

Preventing future outbreaks

Outbreaks are more likely to happen when there are certain triggers. Here are some ways to manage triggers and minimize outbreaks:

Manage stress

Stress is a well-known trigger for cold sore outbreaks. When you're stressed, your immune system weakens, which can give the dormant virus the opportunity to reactivate. 

Incorporating stress-management techniques like meditation, exercise, or even just taking time to relax can make a big difference in reducing the frequency of cold sores. 

Protecting your lips from the sun

Sun exposure is another common trigger for cold sores. The ultraviolet (UV) rays from the sun can weaken your skin’s defenses and lead to an outbreak. 

To protect yourself, make it a habit to use a lip balm that contains SPF whenever you’re outside, even on cloudy days. This simple step can prevent the sun’s rays from triggering an outbreak and keep your lips healthy and cold sore-free.

Maintaining a healthy lifestyle

A strong immune system is your best defense against frequent cold sore outbreaks. Eating a balanced diet rich in vitamins and nutrients, staying hydrated, and getting enough sleep are all essential to maintaining your body’s natural defenses. 

Regular exercise can also boost your immune system, making it harder for the virus to reactivate.
