Nothing will spoil your day like breaking out with a cold sore. But worry not, we give you some of our best tips, tricks and home remedies for dealing with cold sores.

Not only are they painful and itchy, but they’re near impossible to hide. Given that they tend to rear their ugly heads when you’re rundown and tired, it can feel like they add insult to injury (literally).


For many of us, they’re also are a recurring problem too. Once you have the cold-sore virus, it stays in your body for the rest of your life, leaving you fearful of your next random outbreak.

With that in mind, we spoke to Dr Petra Simic, clinical director at Bupa Health Clinics, to find out how to look and feel your best during cold sore season.

What exactly are cold sores?

“Cold sores, known as herpes simplex virus (HSV), are clusters of tiny blisters that appear on the lip or around the mouth. While they can cause a lot of pain and make you feel self-conscious, they tend to disappear without scarring,” explains Dr Simic.

“The virus is passed on by saliva. Kissing is the most common way it is spread from person to person. It passes through the skin and travels up the nerves where it will lay dormant until triggered.

“There are a number of triggers that fuel an outbreak, particularly at this time of year when our immune systems can be lower. Feeling emotional, rundown and tired are all factors that can leave you at risk.”

Home remedies for cold sores

Act fast

The first sign that a cold sore is on its way is a tingling or itching feeling. “Some people describe it as a burning sensation,” says Dr Simic.

When you feel the first twinges of a cold sore, he recommends starting treatment immediately. “This will slow it down and help manage the outbreak,” he advises.

“Over-the-counter treatments won’t stop the outbreak, but it will reduce the reproduction of the virus and relieve the symptoms.”

Ice, ice, baby

Rubbing an ice cube over the sores or placing a cool, damp flannel over them for five to ten minutes can also reduce redness and irritation.

This might be particularly useful before a zoom meeting if you’re feeling self-conscious as it will temporarily reduce the appearance of the cold sore.

Wait it out and manage the pain

Sadly, if you do find yourself with a cold sore this winter, there’s very little you can do but wait for the blisters to heal.

“Ibuprofen can help ease painful symptoms too. Unfortunately, there isn’t a treatment that eradicates the virus completely,” says Dr Simic.

You can also apply a local anesthetic cream such as lidocaine or benzocaine, which temporarily blocks the skin’s nerve signals helping to numb pain and stop any itching

Can you safely cover up a cold sore?

“Covering up a cold sore with concealer or other make-up isn’t advised,” warns Dr Simic. “Especially during the early stages, because it can help spread the infection and make the situation worse.

“If a cold sore becomes infected with bacteria it can cause impetigo – another highly-infectious skin condition that causes blisters and sores.”

If you want to try and hide your cold sore with make-up, he advises waiting until it’s reached the ‘scab’ stage. Apply a thin layer over cold sore cream, so that the cosmetics aren’t directly touching the sore.

“If make-up is applied then it’s important to dispose of any lipsticks or applicators that have been used to minimise the chance of the virus spreading,” he adds.

A final tip? “If a skin condition persists and starts to impact your quality of life, go and see your GP or book an appointment with a dermatologist.”
