What is keratosis pilaris
Keratosis pilaris is a common inherited skin condition affecting hair follicles, so called chicken skin. The skin cells at the opening of the follicle form a plug that protrudes through the opening and has a ring of irritated skin around it. Sometimes it is mistaken for acne, but the white cap on the hair follicles is not pus, it's dry dead skin cells.
It is more common in children than adults, as many of us grow out of this condition. It is related to atopic dermatitis or eczema, and tends to run in families with allergies, hay fever, eczema and asthma.
