Medicines for Keratosis pilaris

What it is

Keratosis pilaris is an extremely common and completely harmless skin condition in which small, rough bumps appear, giving the skin a texture sometimes described as "chicken skin" or like fine sandpaper. It happens when a protein called keratin builds up and blocks the tiny hair follicles. The bumps are usually skin-coloured, red or brownish, and are most often found on the backs of the upper arms, the thighs, the buttocks and sometimes the cheeks. It is more common in children and younger people, in those with dry skin or eczema, and it often improves with age. It is not infectious, not a sign of poor hygiene, and not harmful — but some people find it bothers them cosmetically.

How it is treated

Keratosis pilaris cannot be cured, but its appearance and roughness can usually be improved, and it often fades over time. The mainstays are simple skin care: regular moisturising to soften the skin, gentle exfoliation, and avoiding harsh soaps and very hot water that dry the skin. Moisturisers containing ingredients that help shed dead skin (such as urea or certain acids) can be particularly helpful. Being gentle rather than scrubbing hard is important, as irritation can make it look worse. Reassurance that it is harmless is a key part of managing it. If the skin becomes very red, itchy or inflamed, a doctor or pharmacist can advise on additional measures.
