Dermatitis affects roughly 30% of children and 10% of adults, yet most people still don’t understand what type they have, what’s triggering their flares, or that effective treatments exist beyond basic moisturizer.
Dermatitis is a broad term for skin inflammation that presents in several distinct forms. The most common, atopic dermatitis (often called eczema), involves a genetic defect in the skin’s protective barrier that allows moisture to escape and irritants to penetrate.
Contact dermatitis, by contrast, is an immune reaction to specific substances your skin touches. Seborrheic dermatitis targets oil-rich areas like the scalp and face. Each type has different triggers, different progression patterns, and responds to different treatments.
Getting the right diagnosis matters more than most people realize. A moisturizer that helps atopic dermatitis may do nothing for contact dermatitis if you haven’t identified and eliminated the allergen causing it.
The skin barrier is not just a wrapper. It’s an active immune organ. When ceramides and filaggrin are deficient (as in atopic dermatitis), everything from dust mites to fragrance can trigger an inflammatory cascade.
