Name a common symptom of eczema.

One of the hallmark symptoms of eczema is itchy, inflamed skin. This condition, also known as atopic dermatitis, often leads to significant discomfort due to the intense itching that frequently accompanies it. As individuals scratch the affected areas, the skin can become more inflamed, resulting in a cycle of irritation that exacerbates the condition. This inflammation is typically characterized by redness, swelling, and sometimes even blistering, making it a key indicator of eczema.

The other symptoms listed do not align as closely with eczema. For example, dry, cracked lips can occur for various reasons, such as dehydration or environmental factors, but they are not defining characteristics of eczema. Excessive oiliness is more indicative of other skin conditions, such as acne or seborrhea, and skin tightening is often related to conditions like dryness or aging rather than eczema itself. Thus, itchy, inflamed skin stands out as the most relevant and common symptom associated with eczema.
