Sunburn is better prevented than treated. Effective sunscreens are available in a wide variety of strengths. Most doctors recommend a sunscreen SPF level of 30 or greater.

Sunscreen should be generously applied. If out in the sun for a prolonged period of time during the day, wearing a hat and other protective clothing is recommended. Light clothing reflects the sun most effectively.

If you do get a sunburn:

• Try taking a cool shower or bath or placing wet, cold wash rags on the burn.
• Avoid products that contain benzocaine, lidocaine, or petroleum (like Vaseline).
• If blisters are present, dry bandages may help prevent infection.
• If your skin is not blistering, moisturizing cream may be applied to relieve discomfort.
• Over the counter medications, like ibuprofen, may help to relieve pain from sunburn. (Aspirin should be avoided in children who are running a fever.)

Call your doctor if you have a fever with the sunburn or if fluid-filled blisters, dizziness, or vision problems occur with it.

The doctor will perform a physical exam and look at your skin. You may be asked questions about your medical history and current symptoms, including:

• When did the sunburn occur?
• How often do you get sunburn?
• Do you have blisters?
• How much of the body was sunburned?
• What medicines do you take?
• Do you use a sunblock or sunscreen? What type? How strong?
• What other symptoms do you have?
