The short answer
For sunburned lips, use cool compresses, bland moisturization, sun protection, and medical review for severe or unusual symptoms. Do not peel blisters or apply irritating products to broken skin.
How does ultraviolet injury affect the lips?
Sunburn is ultraviolet injury to the lip skin, which can cause redness, heat, tenderness, swelling, peeling, or fluid-filled blisters. The vermilion border is especially exposed because it has less protective pigment than many other skin areas.
What can you apply to help sunburned lips heal?
Cool the lips with a clean damp cloth, apply a bland fragrance-free emollient, drink fluids, and protect the area with a lip product that provides ultraviolet protection. Avoid picking, harsh exfoliants, numbing products that sting, and further sun exposure while the skin heals.
When should severe sunburned lips be assessed?
Seek medical or dental assessment for extensive swelling, pus, fever, eye symptoms, repeated blistering, or a sore that does not heal. A persistent crusted or changing lip lesion should not be assumed to be sunburn.
What should you ask about treatment for a lip lesion?
Ask whether the lesion looks like ultraviolet injury or another lip condition and whether a prescribed treatment is appropriate. Ask how to protect the lips during outdoor activity and when a persistent area should be reviewed again.
Frequently asked questions
Should I pop a lip sunburn blister?
No. Leave the blister intact and keep the area clean while it heals.
Can cold sores look like sunburn?
Yes, some conditions overlap in appearance, so recurrent or clustered blisters need clinical assessment.
