Can chapped lips cause a blister or fissure?
Severely dry, cracked lip skin can form a small blister or fissure, but cold sores, contact reactions, and infection can look similar.
How can chapping damage the skin of the lips?
Chapping damages the lip barrier and creates cracks. Grouped blisters, tingling, crusting, or recurrence may suggest another cause.
What can you do for a blister from chapped lips?
Avoid licking, biting, and peeling, and apply a bland protective lip ointment. Do not burst the lesion.
When should a chapped-lip blister be assessed?
Seek assessment if it is severe, recurrent, spreading, infected-looking, or not healing.
What should you ask about a blister on a chapped lip?
Ask whether it fits chapping, a cold sore, allergy, trauma, or infection.
