Excessive-level abstract: It’s not only one factor. “Eczema is an umbrella time period for inflammatory pores and skin situations,” Kristel Polder, MD, a board-certified dermatologist and adjunct assistant professor on the College of Texas Southwestern Division of Dermatology, tells SELF. In keeping with the American Academy of Dermatology, there are literally seven several types of eczema. Whereas there are variations amongst them, frequent signs happen throughout the board: Many individuals with eczema develop scaly, itchy pores and skin that may be crimson, purple, brown, or ashy grey in colour, relying in your pores and skin tone, Peter Lio, MD, medical assistant professor of dermatology on the Feinberg College of Medication at Northwestern College and member of the Nationwide Eczema Affiliation’s Scientific & Medical Advisory Council, tells SELF.
What most individuals name “eczema”—a rash-like patch of infected pores and skin—is often atopic dermatitis (AD), Dr. Lio says. (That is the most typical kind of eczema, so it is sensible that the 2 phrases are sometimes used interchangeably.) By way of what causes AD: “Quite a few elements contribute to atopic dermatitis.

Allergic contact dermatitis is rather more particular person, as a result of it’s attributable to allergens which are distinctive to every individual.1 (Discovering out what these are is the place a patch check is available in—extra on that in a second.)
