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
Thin skin: What causes it?
My mother is 85 years old. Her skin is so thin that if she bumps against something, her skin tears open. What causes this? Is there anything we can do to counteract this effect?
Answer
from Lawrence E. Gibson, M.D.
Fragile or thin skin that tears easily is a fairly common problem, especially in older adults. Several factors may contribute to thin skin:
- Aging. With increasing age, your skin becomes thinner and loses some of the protective fatty layer that helps cushion your blood vessels against injury.
- Sun exposure. Excessive sun exposure breaks down collagen and elastin fibers in the deep layer of your skin (dermis). Over time, your skin loses elasticity and becomes more fragile.
- Genetics. Genetics may play a role in how your skin ages as well as how susceptible it is to sun damage.
- Side effect of medication. Certain medications, such as long-term use of oral or topical corticosteroids, can weaken skin and the blood vessels in skin.
- Certain medical conditions — such as amyloidosis, Ehlers-Danlos syndrome or bleeding disorders — can affect skin.
Thin skin isn't necessarily a sign of a serious underlying medical condition but should be evaluated by a doctor to determine its cause. To protect thin skin and prevent tears and cuts:
- Wear long-sleeved shirts and long pants
- Avoid prolonged sun exposure
- If you must be outside in the sun, use a broad-spectrum sunscreen with a sun protection factor (SPF) of at least 15
- Keep skin well moisturized and protected by using a quality moisturizing cream, such as Vanicream, Cetaphil or Eucerin
