Eczema Knowledge Hub

Eczema, also known as atopic dermatitis, affects an estimated 204 million people worldwide—around 101 million adults and 103 million children.^[1] If you are living with eczema, you are far from alone.

It is a long-term skin condition that makes the skin red, dry, and intensely itchy. These rashes tend to flare and settle over time. The severity of eczema is usually assessed and categorized as mild, moderate, or severe, depending on how much of the skin is affected and how intense the itching becomes.^[2] Beyond the skin itself, eczema can seriously affect sleep, mood, and overall quality of life.^[2]

Although eczema is not contagious, it can run in families and be influenced by genetics.^[3] This is why doctors often diagnose eczema by examining the skin, asking about symptoms such as dry itchy patches, typical locations like the creases of the elbows and knees, and any family history of allergies or asthma.

Because other skin conditions can look similar, it is always a good idea to see a healthcare professional if your eczema spreads, becomes very painful, or shows signs of infection (such as yellow crusting, pus, or worsening redness).
