Atopic eczema and xerosis


By Jill Malek This education module is independently researched and compiled by PSA-commissioned authors and peer reviewed.

Atopic eczema is a chronic,


itchy skin condition that is
commonly called ‘eczema’. It is
also known as atopic dermatitis or
neurodermatitis.1 Atopic eczema
is very common in children,
but can occur at any age.1
It accounts for about 60% of all
inflammatory skin conditions.2

Xerosis (dry skin) is a known
