The short answer: For most people, chicken skin (keratosis pilaris) is not permanent in the strict sense: it often improves gradually, and many cases fade by the mid-20s or 30s. It does persist in a sizable minority of adults, though, and there is no cure, only treatment that keeps it smoother while you use it. The rare exception is a scarring variant on the face, where the scars and eyebrow hair loss can be permanent.
“Chicken skin” is the everyday name for keratosis pilaris (KP), the rough, bumpy texture that the American Academy of Dermatology (AAD) says can resemble the skin of a plucked chicken or goosebumps. People who have lived with it since childhood usually want to know one thing: will it ever go away on its own?
The honest answer is “probably, slowly, but not guaranteed.” Here is what the evidence supports.

What chicken skin actually is
KP happens when keratin, a protein in the outer layer of skin, builds up and plugs hair follicles. The result is small, rough bumps, most often on the upper arms and thighs. DermNet describes it as harmless and very common, affecting an estimated 50 to 70% of teenagers and around 40% of adults. It isn’t contagious (Cleveland Clinic).
On fair skin, the bumps can look skin-colored, white, red or pinkish purple. On darker skin they often look brown to black, according to the AAD. For the full picture of causes and care, see our keratosis pilaris guide.
Does chicken skin go away? What the research shows
Most of what we know about the long-term course of KP comes from clinical experience and a small number of studies. They point in the same direction, with an important caveat.
The guidance from medical organizations
The AAD says that for many people, KP goes away with time even without treatment, and that clearing tends to happen gradually over many years (AAD). Cleveland Clinic states that most cases start to clear around the mid-20s and that KP usually disappears completely by age 30. DermNet notes that it often clears during adult life. The NHS is more cautious: most people have it for years, and it “may eventually clear up by itself” (NHS).
The one study that followed patients over time
The most cited data come from a 1994 British survey of 49 people diagnosed with KP over the previous 20 years (Poskitt and Wilkinson). The results were mixed:
- 35% said their KP had improved with age, at an average age of 16.
- 43% said it had stayed the same.
- 22% said it had gotten worse.
- 80% noticed seasonal changes, typically better in summer and worse in winter.
The study was small, relied on patients’ own recollections, and only included people up to age 25, so it can’t tell us what happens later in adulthood. Still, it is a useful corrective to the idea that KP reliably vanishes after the teen years. The fact that DermNet estimates around 40% of adults have KP points the same way.
| Source | What it says about duration |
|---|---|
| American Academy of Dermatology | Often goes away with time, gradually over many years |
| Cleveland Clinic | Starts clearing in the mid-20s, usually gone by 30 |
| DermNet | Often clears during adult life |
| NHS | Usually lasts years; may eventually clear on its own |
| Poskitt and Wilkinson (1994) | Improved in 35%, unchanged in 43%, worse in 22% of patients up to age 25 |
Key takeaways
- KP commonly improves with age, but improvement is gradual and not guaranteed.
- In the only follow-up survey, about a third of patients improved, and most did not by age 25.
- Treatment improves the look and feel, but results last only as long as you keep it up.
- Permanent changes are rare and mostly limited to scarring variants on the face.
Why chicken skin lingers for some people
Researchers don’t fully understand why KP fades in some people and persists in others, but several factors are linked to it.
- Family history. DermNet notes that KP appears to run in families with autosomal dominant inheritance, and that it has been linked to changes in filaggrin, a protein important to the skin barrier. In the 1994 survey, 39% had a family member with KP.
- Eczema and dry skin. Cleveland Clinic lists eczema, ichthyosis vulgaris and dry skin among the risk factors. In the British survey, 37% of patients had a personal history of atopic conditions such as eczema, asthma or hay fever.
- Other conditions. Cleveland Clinic also lists asthma, hypothyroidism, diabetes, obesity and Down syndrome as associated with KP.
- Climate. Dry, cold air makes KP more noticeable. DermNet links its winter flares to reduced moisture in the air.
None of these mean KP is a sign of illness. They simply help explain why the same skin trait can last into adulthood for one person and fade for their sibling.
What can leave lasting marks
Typical KP does not scar. A few uncommon forms behave differently. DermNet describes keratosis pilaris atrophicans faciei (also called ulerythema ophryogenes), which begins in infancy or childhood with red bumps on the outer eyebrows and sometimes the cheeks and forehead. It usually becomes less noticeable after puberty, but the thinning (atrophy) of the skin and eyebrow hair loss it causes are permanent (DermNet). This is one reason facial KP in children deserves a dermatologist’s look; we cover it in KP on the face.
Pigment is a separate concern. On brown and Black skin, inflamed bumps can leave dark marks. Gentle care that avoids scrubbing and picking is the best way to reduce that risk.
What you can change
You can’t switch off a genetic tendency, but you can control how much KP shows. Moisturizers containing urea or lactic acid are the AAD’s first recommendation. In a 12-week randomized trial, a 10% lactic acid cream reduced KP lesions by 66% on average and a 5% salicylic acid cream by 52% (Kootiratrakarn et al., 2015). A 2020 systematic review of 47 studies found that lasers had the strongest support of any treatment, while several topical treatments also improved appearance (Maghfour et al.).
What none of these do is cure KP. The AAD states plainly that treatment can’t cure it and that you need ongoing maintenance to keep results. A sustainable approach is a light daily routine you can live with, which we lay out in KP on your arms: a realistic weekly routine. Avoid the tempting shortcut of aggressive scrubbing; we explain why in why scrubbing makes KP worse.
When to see a dermatologist
Ordinary KP doesn’t need medical care. A dermatologist is worth seeing when the diagnosis is uncertain, when KP is widespread or distressing, or when home care isn’t working after several weeks. Our red-flag checklist covers when bumps need a professional opinion.
See a board-certified dermatologist if
- Bumps on a child’s face are paired with redness and thinning eyebrows.
- The bumps are painful, pus-filled or spreading.
- You notice dents, scarring or hair loss in the affected area.
- Your skin is very itchy or inflamed despite moisturizing.
- KP is causing significant distress and home care isn’t helping.
Frequently asked questions
At what age does chicken skin go away?
There is no fixed age. Cleveland Clinic says most cases begin to clear in the mid-20s and are usually gone by 30. In the 1994 survey, patients whose KP improved noticed it at an average age of 16, but most patients had not improved by their mid-20s.
Can chicken skin be cured permanently?
No treatment cures KP. Moisturizers, chemical exfoliants, prescription creams and lasers can make it much less visible, but the AAD notes that results depend on continued maintenance. Many people do see it fade on its own over the years.
Why do I still have chicken skin as an adult?
KP persists into adulthood for a meaningful number of people. DermNet estimates that about 40% of adults have it. A family history, eczema or naturally dry skin may make it more likely to last.
Does chicken skin get worse with age?
For most people it stays the same or slowly improves. In the British survey, 22% of patients said it had worsened. Seasonal swings are common, so a bad winter doesn’t necessarily mean a long-term trend.
Can chicken skin leave scars?
Typical KP does not scar. Rare facial variants can cause permanent thinning of the skin and eyebrow hair loss, and inflamed bumps may leave temporary dark marks on deeper skin tones.
