Can you get a cold sore from sunburn on your lips?

Got lip sunburn on holiday and a cold sore followed a couple of days later. Is that a real link? Seems like UV on the lips is a big cold sore trigger. Anyone else get one after lip sunburn?

Yes, lip sunburn is one of the most reliable triggers for me.

Reflected sun off water or snow catches people out too.

This is exactly why I never skip SPF on my lips now.

Founder here, thank you for opening this up. The pattern I keep coming back to is protection before anything shows: mineral SPF on the lips every morning, sleep protected, wind and cold kept off. Small daily habits move the needle far more than reacting after the fact.
