What Triggers Cold Sore Outbreaks?

For many folks with HSV-1, stress, being sick with the flu or even being on your period can trigger an outbreak. Exposure to the sun can, too, which is why it’s important to use sunscreen on your face and apply a lip balm with SPF. Most times, before an outbreak is coming, your mouth might tingle, itch or burn.
