Eczema, also known as atopic dermatitis, is a common inflammatory skin condition characterized by red, itchy, and inflamed skin. The exact cause of eczema is not fully understood, but it is believed to involve a combination of factors, including:
1. Genetics: A family history of eczema or other allergic conditions like asthma or hay fever can increase the likelihood of developing the condition.
2. Immune system response: People with eczema often have an overactive immune system that responds to irritants and allergens in the environment, leading to inflammation.
3. Environmental factors: Exposure to allergens, irritants, or triggers such as certain soaps, detergents, or weather conditions can exacerbate eczema symptoms.
4. Skin barrier dysfunction: The skin of those with eczema may not provide an effective barrier, allowing allergens and irritants to penetrate more easily and cause inflammation.
