Keratosis pilaris is a harmless skin condition that causes clusters of small, rough bumps, most often on the upper arms, thighs, buttocks and cheeks. The bumps form when keratin, a protein in the skin, builds up and plugs the hair follicles. It is so common that many people in Singapore have it without ever realising it has a name, and it is sometimes nicknamed ‘chicken skin’ because of its texture.
This guide explains what keratosis pilaris is, why it happens, and how it can be managed. The key message is reassuring: it is benign, not contagious and not a sign of poor hygiene. While it cannot be completely cured, simple skincare measures can smooth the skin and reduce its appearance.

What is keratosis pilaris?
Keratosis pilaris is a common, harmless skin condition in which small rough bumps appear where hair follicles become plugged with keratin, a protein that protects the skin. The bumps are usually skin-coloured, red or brownish, and the skin can feel like sandpaper or look a little like permanent goosebumps.
It is very common, especially in children and young adults, and often runs in families. It tends to appear on the upper arms, thighs, buttocks and cheeks. It is completely benign – it is not an infection, not contagious and not a sign of poor hygiene – and it often becomes less noticeable with age.
Symptoms & signs
Keratosis pilaris is usually easy to recognise. Typical features include:
- Small, painless bumps, often on the upper arms, thighs, buttocks or cheeks
- Skin that feels rough or dry, like sandpaper
- Bumps that may be skin-coloured, red, brown or whitish
- Occasional mild itch
- Skin that can look worse when dry, such as in air-conditioned environments
It does not usually cause any discomfort beyond the appearance and occasional itch, and it does not lead to scarring when left alone.
Causes & risk factors
Keratosis pilaris happens when keratin builds up and plugs the opening of hair follicles, forming the small bumps. The exact reason this occurs is not fully understood. Factors linked to it include:
- A family history of the condition
- Dry skin, which tends to make it more noticeable
- Having eczema or a tendency to dry, sensitive skin
- Being a child or young adult, though it can occur at any age
It is not caused by anything you have done and is not related to cleanliness. Frequent exposure to air-conditioning and dry skin can make the bumps look more prominent.
How it's diagnosed
Keratosis pilaris is almost always diagnosed simply by looking at the skin. A doctor or dermatologist can usually recognise it from its typical appearance and the areas affected, without the need for any tests.
Occasionally, if the appearance is unusual or another condition is being considered (for example certain rashes or follicle problems), a dermatologist may examine the skin more closely or, very rarely, take a small skin sample. In most cases, however, no investigations are needed and the diagnosis is straightforward.
Treatment options
Keratosis pilaris cannot be fully cured, but its appearance can be improved and the skin kept smoother with simple measures:
- Moisturise regularly – especially after bathing, to soften the skin and ease roughness
- Gentle exfoliation – to help loosen the keratin plugs, without harsh scrubbing that can irritate the skin
- Lukewarm, shorter showers – and a gentle, soap-free cleanser, since hot water and harsh soaps dry the skin
- Topical treatments – certain creams containing ingredients that gently break down keratin or smooth the skin; a dermatologist can advise on stronger options
Improvement is gradual and the condition often returns if treatment stops, so it is best thought of as ongoing management rather than a one-off cure. Many people find it eases naturally with age.
When to see a doctor & which specialist
Keratosis pilaris is harmless and does not need urgent treatment. However, it is worth seeing a doctor if the bumps become very itchy, red, sore or inflamed, if they are spreading or changing in a way that worries you, or if home measures are not helping and the appearance is bothering you. A doctor can confirm the diagnosis and suggest stronger treatments or rule out other skin conditions. As this is a benign condition, calling 995 is not required.
For persistent or troublesome cases, the relevant specialist is a dermatologist. You can find one through our directory of best dermatologists in Singapore.
A simple daily routine that helps
Keratosis pilaris responds best to gentle, consistent care rather than aggressive treatment. A realistic routine might look like this:
- Cleanse with a mild, soap-free wash and keep showers lukewarm and short.
- Pat the skin dry and apply a moisturiser while the skin is still slightly damp to lock in moisture.
- Exfoliate gently a few times a week, using a soft cloth rather than harsh scrubbing, which can irritate and redden the skin.
- Resist the urge to pick or squeeze the bumps, as this can cause soreness or marks.
Special situations
Keratosis pilaris is very common in children and often improves on its own as they grow, so gentle moisturising is usually all that is needed. In Singapore’s climate, frequent time in air-conditioning can dry the skin and make the bumps look more obvious, so regular moisturising is especially helpful. During pregnancy, stick to simple moisturising and check with your doctor before using any medicated creams.
Common questions
Will it ever go away completely?
It cannot usually be cured, but it often becomes less noticeable with age, and good skincare keeps it smoother in the meantime.
Is it caused by poor hygiene or diet?
No. It is a harmless build-up of keratin in the hair follicles, often running in families, and is not related to cleanliness or anything you have eaten.
Do I need to see a dermatologist?
Not for most cases. See one if the bumps become very itchy, sore or inflamed, if they spread or change in a worrying way, or if home measures are not helping.
