While these two skin conditions share similar symptoms, the underlying causes of each are different. For example, dry skin is generally characterized by a lack of moisture in the skin which can be triggered by various factors including environmental (heat, cold or humidity), excessive washing with harsh cleansers, aging, and certain medical conditions. Dry skin’s primary symptoms include flakiness, roughness, and overall feeling of discomfort, but does not involve inflammation and the development of rashes/lesions.
Eczema or atopic dermatitis, on the other hand, is a chronic disorder characterized by inflammation, redness, itching, and rashes or lesions. It oftentimes has a genetic component related to the immune system and an impaired, compromised skin barrier. Unlike dry skin, because eczema involves inflammation and a compromised skin barrier, the effects of eczema are usually much worse because they can cause infection caused by excessive scratching, blisters, and plaques.
