Eczema is a skin condition that causes dry and itchy patches of skin. It can affect anyone at any age, and symptoms usually appear during childhood and last into adulthood. While the exact cause of eczema is unknown, researchers know that people develop eczema because of an interaction between genes and environmental triggers. Atopic dermatitis is the most common type of eczema, and it results from an overactive immune system that causes the skin barrier to become dry and itchy.
Here are some common triggers of eczema:
- Irritants such as soaps, detergents, and bubble bath products
- Environmental factors or allergens such as cold and dry weather, dampness, and specific things like pollen, dust mites, and pet dander
- Extended exposure to dry air, extreme heat or cold
- Some types of soap, shampoos that cause dander, bubble bath products, body wash, and facial cleansers
- Laundry detergents and fabric softeners with chemical additives
People with atopic eczema often have very dry skin because their skin is unable to retain much moisture. This dryness may make the skin more likely to react to certain triggers, causing it to become itchy and sore. If you have eczema, there are steps you can take that may prevent eczema flare-ups and outbreaks, including a good skin care routine and avoiding triggers that cause your symptoms to worsen.
