The short answer
Sunburned lips usually improve with cooling, moisture, and protection from more sun; seek care for severe swelling, blisters, infection, or symptoms that do not settle.
What causes inflammation and injury on sunburned lips?
Sunburn of the lips is inflammation and surface injury caused by ultraviolet radiation. The vermilion border has thin, exposed skin, so it can become red, tender, dry, swollen, or blistered.
What should you do now to cool and moisturise your lips?
Rinse gently with cool water and apply a bland, fragrance-free lip ointment such as petrolatum. Drink fluids, avoid picking peeling skin, spicy foods, and further sun, and use a lip product with broad-spectrum sun protection once the surface is intact.
When do sunburned lips need dental or medical assessment?
Arrange dental or medical assessment if swelling affects eating or breathing, blisters are extensive, pus or spreading redness develops, or pain is worsening rather than easing. Recurrent or persistent lip sores need examination.
What should you ask about ointments and signs of infection?
Ask whether the injury is limited to sunburn, which ointment is appropriate for your medical history, and which changes would suggest infection or another lip condition.
