Those pesky cold sores often appear right when you're enjoying a sunny vacation. Is it just bad luck, or is there more to it?
No coincidence here
Sunlight is a well-known trigger for cold sore outbreaks. Studies, including research from 2020, show the risk of lip blisters rises significantly during holidays in the sun.
Proven tips to minimize cold sore risks
– Apply lip balm with SPF and keep it personal—don't share.
– Shield your face with a hat or cap. For those with ocular herpes, add UV-protective sunglasses.
– Pack an antiviral cold sore cream and apply at the first tingle.
