State three causes of eczema.

Here are three causes of eczema:

• Genetics: Eczema often runs in families, suggesting a genetic predisposition.
• Environmental triggers: Exposure to irritants like soaps, detergents, certain fabrics, or allergens such as pollen, dust mites, and pet dander can cause flare-ups.
• Immune system dysfunction: An overactive immune system can lead to inflammation in the skin, contributing to eczema symptoms.
