Are defects in the skin or blood cells linked to eczema and allergies?

ANSWER

Some research suggests that people with eczema have a defect in their skin barrier. Small gaps in the skin make it dry out quickly, and let germs and allergens into the body. This prompts the body to make chemicals that lead to redness and swelling. Research also points to a problem with a type of white blood cell that releases chemicals that help control allergic reactions in the body. This may explain why people with eczema have outbreaks when they’re around allergens.
