Eczema (Atopic Dermatitis)
Eczema (Atopic Dermatitis) — a chronic, relapsing inflammatory skin condition marked by dry, itchy, red or discolored patches and a weakened moisture barrier. It often begins in childhood and is linked to genetics, immune reactivity, and environmental triggers, though it can appear at any age.
Key points
- It is associated with a compromised skin barrier, partly linked to reduced filaggrin protein, which allows moisture loss and irritant entry.
- Common triggers include harsh soaps, fragrance, temperature changes, sweat, stress, and certain fabrics like wool.
- Gentle, fragrance-free moisturizers with ingredients such as ceramides, glycerin, and colloidal oatmeal help support the barrier and reduce flare frequency.
- It frequently coexists with other atopic conditions like asthma and allergic rhinitis, a pattern often called the atopic march.
Frequently asked
Is eczema contagious?
No, eczema cannot be spread from person to person because it results from genetic and immune factors combined with barrier dysfunction, not an infection.
What ingredients should I avoid with eczema-prone skin?
Fragrance, essential oils, high concentrations of alcohol, and harsh sulfate cleansers can aggravate eczema, so gentle fragrance-free formulas are generally preferred.
