Eczema

Also known as: Atopic Dermatitis, Atopic Eczema

Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition that causes dry, itchy, and inflamed patches of skin. It is most common in children but can occur at any age and often runs in families with a history of allergies or asthma. While there is no cure, proper skincare and treatment can effectively manage symptoms and prevent flare-ups.

Dry, cracked, or scaly skin

Red to brownish-gray patches on the skin

Small raised bumps that may ooze fluid when scratched

Thickened, leathery skin from chronic scratching

Raw, swollen, or sensitive skin from scratching

Darkened skin around the eyes

Causes

Genetic mutation affecting the skin barrier protein filaggrin
Overactive immune system response to irritants
Environmental triggers such as allergens and pollutants
