The skin is the largest organ of the body with a total area of about 20 square feet—though it's often the most neglected part of your body, which can be concerning, since your skin often manifests other issues happening within your body. People with eczema know this better than most and should take special care.

About those sebaceous glands…

Although there are several types of eczema, studies show seborrheic dermatitis is the type most often triggered by stress.

"Seborrheic dermatitis/eczema is an inflammatory skin condition caused by an overgrowth of yeast which reacts negatively with the oils on the skin," explained Tristi Edwards, a Jamaica-based dermatologist. "It's common and noncontagious. 'Seborrheic' refers to the sebaceous glands, while 'derm' means skin. It's called dandruff—or pityriasis capitis—when it's found on a teenager's or adult's scalp, and 'cradle cap' when it's on a baby's head.
