As a dermatologist with years of experience, I've observed and studied the complexities of eczema, a condition that affects millions worldwide. Eczema, scientifically known as atopic dermatitis, is a chronic inflammatory skin condition characterized by itchy, red, and inflamed skin. While the exact cause of eczema is not fully understood, it is widely accepted that it is a multifactorial condition influenced by a combination of genetic, environmental, and immune system factors.
Genetics play a significant role in the development of eczema. Individuals with a family history of eczema, asthma, or allergies are more likely to develop the condition. Genetic predisposition can affect the skin barrier function and immune response, making it easier for allergens and irritants to penetrate the skin and trigger an inflammatory response.
Environmental factors are also crucial in the development and exacerbation of eczema. Exposure to allergens such as pollen, dust mites, and pet dander can worsen symptoms. Additionally, environmental irritants like harsh soaps, certain fabrics, and even weather changes can contribute to skin inflammation.
The immune system's response is another key factor in eczema. The condition is associated with an overactive immune system that reacts to environmental triggers, leading to inflammation. This overreactive immune response is thought to be linked to imbalances in the skin's microbiome, which can affect how the immune system perceives and responds to potential threats.
Skin barrier dysfunction is central to eczema. The skin acts as a barrier to protect the body from external irritants and allergens. In individuals with eczema, this barrier is compromised, allowing for easier penetration of substances that can cause inflammation.
Stress is another factor that can trigger or worsen eczema symptoms. Psychological stress can affect the immune system and increase inflammation throughout the body, including the skin.
Infections can also play a role in eczema. The skin of individuals with eczema is more susceptible to bacterial and viral infections, which can further exacerbate the condition.
Hormonal and dietary factors have been suggested as potential contributors to eczema, although more research is needed to fully understand their roles. Hormonal imbalances and certain foods may trigger or worsen symptoms in some individuals.
In conclusion, eczema is a complex condition with no single cause. It is the result of a delicate interplay between genetic predisposition, environmental exposures, immune system responses, and skin barrier integrity. Understanding these factors can help in managing and treating eczema more effectively.

The most common type of eczema -- atopic dermatitis -- resembles an allergy. But the skin irritation, which is more often seen in children rather than adults, is not an allergic reaction. The current thinking is that eczema is caused by a combination of factors that include: Genetics.Jun 22, 2017
