What is the direct answer?
Sunburned lips are irritated by ultraviolet exposure; cool compresses, hydration, and bland lip protection can support healing.
What does this question mean?
The lips have thin exposed skin that ultraviolet radiation can injure, causing redness, warmth, tenderness, dryness, peeling, or blisters.
What can you do next?
Use a cool damp compress, drink fluids, and apply bland fragrance-free moisturizer. Protect the lips from further sun and do not peel blisters or flaking skin.
When should you seek dental care?
Seek care for extensive blistering, severe swelling, pus, worsening pain, fever, or inability to drink. A persistent or recurring sore should be examined.
What should you ask the dentist?
Ask whether the lesion fits sun injury or another condition, which ingredients to avoid, and how to protect the lips outdoors.
