Eczema, also known as atopic dermatitis, is a chronic skin condition that leads to dry, itchy, red, and inflamed patches on the skin. It can occur anywhere on the body, but it’s most common on the face, hands, elbows, and knees. This condition is often linked to an overactive immune response, environmental triggers, or genetic factors. Eczema can flare up periodically and may cause discomfort, but with the right management, symptoms can be controlled to improve skin health and hydration.
