Eczema, also known as atopic dermatitis, is characterized by dry, itchy, and inflamed skin. It often appears in the first six months to five years of life and may be associated with a family history of allergies or asthma. A common presentation includes red, inflamed patches on the cheeks, arms, and legs. Managing eczema involves keeping the skin moisturized, avoiding triggers, and sometimes using topical corticosteroids.
