Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition characterized by red, itchy, and inflamed patches of skin. It can affect people of all ages and is often linked to a combination of genetic, environmental, and immune factors. Symptoms can vary in severity and may include dryness, flaking, and sometimes oozing or crusting. While there is no cure, treatment options such as moisturizers and topical steroids can help manage symptoms and flare-ups.
