If the skin on your upper arms, thighs, or cheeks feels rough, like fine sandpaper or permanent goosebumps, you may have keratosis pilaris. It is extremely common, completely harmless, and often called “chicken skin.” This guide explains why it happens and what actually helps to smooth it.
What is keratosis pilaris?
Keratosis pilaris is a very common, harmless skin condition that causes small, rough bumps, usually on the backs of the upper arms, the thighs, the buttocks, and sometimes the cheeks. The bumps may be skin-coloured, red, or brown, and the skin can feel dry and rough.
It happens when a protein in the skin called keratin builds up and blocks the opening of hair follicles, forming tiny plugs. This creates the bumpy texture.
Quick answer: Keratosis pilaris is a harmless build-up of keratin that blocks hair follicles, causing small rough bumps. It cannot be fully cured but can be softened with consistent skincare.
What does it look and feel like?
- Small, rough bumps in clusters
- Skin that feels like sandpaper or goosebumps
- Bumps that may be red, brown, or flesh-coloured
- Dryness in the affected area
- Usually no pain, though it can occasionally itch
It is often more noticeable in drier conditions and may improve in humid weather, which can mean it looks better in Singapore’s climate but worse in air-conditioned environments that dry the skin.
Why do I have it?
Keratosis pilaris is largely down to genetics, so it often runs in families. It is more common in people who also have dry skin or eczema. It frequently appears in childhood or the teenage years and can become less noticeable with age.
It is important to know that keratosis pilaris is not caused by poor hygiene, and it is not contagious. You have not done anything to cause it.
Is it harmful?
No. Keratosis pilaris is harmless and does not cause any medical problems. Most people seek help simply because they do not like the texture or appearance, which is a perfectly reasonable reason to want it managed.
How do I get rid of chicken skin?
There is no permanent cure, but consistent care can make a real difference to texture. General approaches include:
- Gentle exfoliation. Mild exfoliating ingredients (such as products containing lactic acid, salicylic acid, or urea) can help loosen the plugs. Harsh scrubbing is best avoided, as it can irritate.
- Moisturising. Regular use of a good moisturiser keeps the skin soft and reduces roughness. Creams with urea or lactic acid are often suggested.
- Avoiding very hot showers, which can dry the skin further.
- Patience and consistency. Improvement is gradual, and the condition often returns if care stops, so it is about ongoing management rather than a one-time fix.
For stubborn cases, or where redness or pigmentation is a concern, a skin clinic in Singapore can advise on stronger prescription creams or in-clinic treatments and confirm the diagnosis.
When is it worth seeing a doctor?
You do not need to see a doctor for mild keratosis pilaris. Consider a visit if:
- The bumps are very red, inflamed, or itchy
- You are unsure whether it is keratosis pilaris or another condition
- Home care has not helped and the appearance bothers you
- There is associated pigmentation or scarring you would like assessed
A dermatologist can confirm it is keratosis pilaris (rather than acne, a rash, or a fungal issue) and suggest a realistic plan.

FAQs
Is keratosis pilaris the same as acne?
No. Acne involves blocked pores, blackheads, and inflamed spots. Keratosis pilaris is a build-up of keratin around hair follicles that causes rough bumps, usually on the arms and thighs.
Can keratosis pilaris be cured?
There is no permanent cure, but regular exfoliation and moisturising can noticeably smooth the skin. It tends to return if care stops, so it is managed rather than cured.
Why is my chicken skin worse sometimes?
It often worsens when skin is dry, such as in air-conditioned spaces, and can look better in humid conditions. Consistent moisturising helps reduce the variation.
