What causes cold sores?
Cold sores are caused by herpes simplex virus 1 (HSV-1), the oral form of the virus. In fact, 67% of the population under age 50 has HSV-1 because it is so contagious.1 Once you are infected, the virus never leaves your body. Most people aren’t exactly sure when they first encountered the virus. It’s usually contracted in early childhood, when it may not appear as a visible cold sore.

What happens when I get a cold sore?
For the majority of people, HSV-1 remains inactive throughout their lives and they may never know they have the virus. Around 1 in 4 people will experience recurrent infections.2 This occurs when the cold sore virus “wakes up,” infects the skin cells in or around the lip or mouth and causes a visible and contagious sore. This usually happens after something has triggered the virus. Find out what your triggers are
