Zovirax Cold Sore Cream is used to treat cold sores.

Cold sores, known medically as herpes labialis are very common and are easily recognised because they often appear as blisters around the lips and mouth.They pop up in response to a viral infection.
They are often uncomfortable and can make some people feel very self-conscious.
The earlier you treat a cold sore, the better.
The best time to start treatment is when that tingling sensation first happens, before any visible sign of cold sore appears.
If you miss it, don't worry, it's not too late to treat!

Stages of the virus
After the itchy, tingly stage, the site of the cold sore gradually develops into a blister or a small group of blisters, surrounded by red and swollen skin.
After a day or so these burst to produce the typical open sore.
Like a sore anywhere on your body, these sores gradually dry up and form a crusty scab, which is usually a yellow-brown colour.
The sore gradually heals.
The scab falls off over a few days and should completely disappear after around 10 days, or faster with the use of Zovirax Cold Sore Cream.
The area may be a bit swollen for few days.
