Eczema is a common skin problem, usually caused by a combination of internal and external factors, and manifests as redness, itching, and dryness of the skin. Understanding its causes and symptoms is helpful for daily care; it is recommended to seek medical attention promptly and pay attention to skin moisturizing.

Specifically:

1. The causes are varied: it may be related to genetic predisposition, such as a weak skin barrier; environmental factors such as dry climate and contact with irritants (such as chemical detergents) may also trigger it; in addition, high stress or dietary sensitivities can sometimes aggravate the condition.
2. Common symptoms: The skin may develop erythema, dryness and peeling, often accompanied by significant itching; in severe cases, small blisters or oozing may occur, and the skin may become thickened and rough after repeated scratching.
In daily care, avoid bathing with excessively hot water, choose gentle skincare products to keep skin moisturized, and wear loose-fitting cotton clothing to reduce friction. If symptoms persist or worsen, consult a doctor for personalized guidance.
