Frequently asked questions
Is eczema contagious?
No. Eczema cannot spread from person to person. It is linked to a sensitive skin barrier and immune response.
Why are moisturisers so important in eczema?
They repair and protect the skin barrier, reducing dryness and itching. Regular use, even when skin looks clear, helps prevent flares.
