The most common type of eczema involves areas of red, dry, itchy skin. Eczema often affects the skin in the creases of your elbows, behind your knees, on your wrists and ankles, on your face and scalp (usually seen in babies). There are some differences in the pattern of eczema and the areas of skin affected based on your skin colour. People of colour may get eczema on the outsides of your knees or elbows, scaly skin, purple, grey or brown areas or irritated skin (not red), round areas of inflammation. Eczema symptoms tend to come and go. When you have symptoms, this is known as an ‘eczema flare'.
Nobody knows exactly what causes eczema, but it can run in families. It's thought to be caused by both genetic and environmental factors.
A trigger is anything that might make your eczema symptoms worse. Some common examples include dry weather, changes in the weather, overheating, stress, skin infections. Other things that can trigger your eczema, if you have contact with them, are skin irritants such as soap, shampoo or bubble bath, sand, carpet or grass, chlorine in pools or spas, woollen or prickly fabrics, sheepskin, substances you are allergic to. Triggers vary from person to person, so not all these things will affect every person with eczema. Identifying your personal triggers will help you manage your eczema.
You should see your doctor if you or your child has itchy, dry skin.
Eczema is a common skin condition that affects both children and adults. Eczema is also known as atopic eczema, atopic dermatitis, allergic eczema. If you have eczema, your skin doesn't keep moisture in very well. So, it becomes dry and easily irritated. This makes your skin more open to irritants and allergens (substances that cause allergies). The allergens can trigger the release of chemicals in your skin, making it itchy. Scratching only makes your skin more itchy, and so the cycle repeats itself. This is known as the ‘scratch and itch cycle'. Most people have their first symptoms when they are babies, and eczema usually gets better as you get older.
