If you’ve ever noticed a cold sore appear after spending time in the sun, you’re not alone. Sun exposure is a commonly reported cold sore trigger.
Extended exposure to sunlight can contribute to dry, irritated or sunburned lips. Heat, dehydration, disrupted sleep and travel-related stress may also affect people who are already prone to outbreaks.
