Dr. Lawrence Gibson likens bad health information on the Internet to food poisoning.
Consumers, he said, need to be aware, and will find reliable information at MayoClinic.com.
Dr. Gibson, a Covington, Ky., native, has been with Mayo since 1986 and is board certified in dermatology, dermatopathology and immunodermatology. He is a professor of dermatology at Mayo Medical School and a consultant in the Department of Dermatology.
Dr. Gibson has been director of the Dermatopathology Laboratory since 1998 and chair of the Laboratory Division in the Department of Dermatology since 2000. He is especially interested in inflammatory disorders of the skin and lymphoma affecting the skin.
"Electronic information is becoming a staple in the diet of a health conscious society," he said. "It's important to avoid misinformation and provide a credible source for health information. Using this analogy, it's critical to avoid 'indigestion' or worse yet, 'food poisoning' by the ingestion of tainted information."

Question
Sunburn treatment: What works?
What's the most effective sunburn treatment? When does sunburn require medical attention?
Answer
from Lawrence E. Gibson, M.D.
Unfortunately, there's no fast-fix sunburn treatment. Once you have sunburn, the damage is done — although it may take 12 to 24 hours after sun exposure to know the full extent and severity of sunburn, and several days or more for your skin to begin to heal.
In the meantime, the most effective sunburn treatment simply helps ease your discomfort:
- Keep it cool. Apply cold compresses — such as a towel dampened with cool water — to the affected skin. Or take a cool bath.
- Keep it moist. Apply aloe, moisturizing cream or over-the-counter hydrocortisone cream to the affected skin. Beware of sunburn treatment products containing anesthetics, such as benzocaine. There's little evidence that these products are effective. In some cases, they may even irritate the skin.
- Leave blisters intact. If blisters form, don't break them. You'll only slow the healing process and increase the risk of infection. If needed, lightly cover blisters with gauze.
- Take an over-the-counter pain reliever. If needed, take anti-inflammatory medication — such as aspirin or ibuprofen (Advil, Motrin, others) — according to the label instructions until redness and soreness subside. Don't give children or teenagers aspirin. It may cause Reye's syndrome, a rare but potentially fatal disease.
- Treat peeling skin gently. Within a few days, the affected area may begin to peel. This is simply your body's way of getting rid of the top layer of damaged skin. While your skin is peeling, continue to use moisturizing cream.
Consult a doctor for sunburn treatment if:
- Severe sunburn covers a large portion of your body with blisters
- Sunburn is accompanied by a high fever or severe pain
- Severe sunburn doesn't begin to improve within a few days
To prevent future episodes of sunburn, use sunscreen frequently and liberally. Common sense counts, too. Cover up while you're outdoors, and stay in the shade as much as possible.
