Keratosis pilaris

Also called Chicken skin

Keratosis pilaris is a common skin condition that causes small bumps, usually on the upper arms, thighs and bottom, and sometimes the cheeks. It happens when a protein called keratin blocks hair follicles. It is harmless, often runs in families and is common in children and teenagers.

What it is

It often gets better with age and tends to be worse in winter.

There is no cure, but moisturisers and creams containing urea, lactic acid or salicylic acid can make the skin smoother.

Common signs

  • Small, rough bumps on the skin
  • Skin that feels like sandpaper
  • Red, brown or skin-coloured bumps
  • Mild itching, sometimes

How it is usually diagnosed

  • Examination of the skin

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Notes on creams that helped

Questions to ask your doctor

  • Which creams could help?
  • Is it linked to eczema?
  • Will it go away?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Bumps that become painful, swollen or filled with pus with fever: get it checked, it may be an infection
