Dermatitis – 3
Narrator: This is NIH Health Matters. I’m Joe Balintfy. Our skin separates the inside of our body from the outside world. Dr. Steven Katz at the NIH explains the skin is a barrier and a guard.
Katz: The skin is the outermost sentinel really for fighting off bacteria, fighting off noxious agents; and if the barrier is broken somehow, you can become more allergic to things. Agents that wouldn't cause a problem on someone with normal skin would cause a problem on individuals with an abnormal skin.
Narrator: He adds there’s an important protein that helps the skin maintain a proper barrier. For more information about the skin, skin diseases and rashes, visit www.niams.nih.gov. Health Matters is produced by the National Institutes of Health, part of the U.S. Department of Health and Human Services.
