unfortunately cold sores are a virus. Some bodies cannot get rid of them altogether but they are made more reocurrent if you regularly come into contact with someone who also has the virus. Such as kissing etc.

One of the most common triggers is UV exposure, so sun protection is a great way to reduce the risk of outbreaks. In addition, getting enough rest and good nutrition, and managing stress, help protect the immune system. When the immune system is working well, it can do a better job of keeping the herpes virus under control.
