What is Blistex Cold Sore Cream?

It is a clinically proven anti-viral treatment for the early relief of cold sores on the lips. It is the only product in the UK to contain the key active ingredient docosanol which works differently from all other cold sore topicals*. Docosanol penetrates the skin to help block the virus and works at an earlier stage in the infection process to help stop the virus from entering cells & spreading.

You can now find Blistex Cold Sore Cream in the Health Care aisles of UK pharmacies and grocers nationwide!

When to use Blistex Cold Sore Cream

For best results, apply at first tingle to help prevent the appearance of a cold sore and aid the healing process. When used correctly Blistex Cold Sore Cream can help heal a cold sore in as little as 2.5 days!

Apply to the affected area 5 times a day at approximately 3 hourly intervals.

What Is a Cold Sore?

A cold sore starts with a tingling, burning sensation to the lip. A blister then appears within 48 hours and can take up to ten days to fully heal. Flu, fatigue, stress and extreme weather conditions are just a few of the common triggers for cold sores, meaning that many people tend to suffer more cold sores during the colder months of the year.

The blister may spread and be irritating or painful whilst it heals, so it’s advised to use a treatment such as Blistex Cold Sore Cream to help aid the healing process.
