Keratosis pilaris is a very common harmless condition where small bumps appear on your skin. It can last for a long time, but there are things that may improve your skin.
Symptoms of keratosis pilaris may include:
You usually get patches of small bumps on your arms, thighs or bottom, but they can appear in other places.
The bumps can be red, white, skin-toned or darker than your skin.
The skin can sometimes feel itchy, and may be better in summer and worse in winter.
Most people with keratosis pilaris have it for years, and it may eventually clear up by itself.
Until it does, there are things you can do to help improve the appearance of your skin.
They can recommend creams or lotion to help your skin. They can also tell you whether you need to see a GP.
Keratosis pilaris happens when your hair follicles become blocked with a build-up of keratin, a substance found in skin, hair and nails.
Nobody knows exactly why keratin builds up, but the condition is thought to run in families. So if your parents have it, you may get it, too.
Keratosis pilaris is not infectious, so you cannot spread or catch it.
