If you've ever noticed small, rough bumps on your upper arms, thighs, or buttocks that just won't go away no matter what you try, you might have keratosis pilaris — one of the most common skin conditions in the UK. Often nicknamed "chicken skin" because of its distinctive texture, keratosis pilaris affects up to 40% of adults and as many as 70% of teenagers. The good news? It's completely harmless, and with the right approach, it can be significantly improved.
Keratosis pilaris (KP) occurs when keratin — a protein naturally found in skin, hair, and nails — builds up inside hair follicles, blocking them and creating the characteristic small bumps. The skin around the bumps can feel rough, like sandpaper, and may appear red, white, brown, or skin-coloured depending on your skin tone.
Nobody knows exactly why keratin accumulates this way, but genetics plays a significant role. If one or both of your parents have it, there's a high chance you'll develop it too. It's also more common in people who have:
KP tends to flare up in winter when the air is drier, and it often improves in summer — something many sufferers notice without realising why. Most people find the condition naturally fades after the age of 30, but for those who are bothered by its appearance, there's plenty you can do in the meantime.
While there's no permanent cure for KP, consistent at-home care can make a dramatic difference. The key is combining exfoliation (to clear blocked follicles) with deep moisturisation (to soften and soothe the skin). According to a 2026 randomised controlled trial, a combined exfoliation-dissolution-repair approach consistently outperforms using any single product alone.
Here are the most effective ingredients to look for:
Lactic acid is considered the gold-standard first-line treatment by dermatologists. A 2015 clinical study found that applying 10% lactic acid twice daily for three months led to a 66% improvement in skin roughness, pigmentation, and overall appearance. It works by gently dissolving the keratin plugs and smoothing the skin's surface. Look for body lotions or serums containing 5–12% lactic acid and apply consistently after bathing.
Urea is a powerful humectant and keratolytic agent — meaning it both draws moisture into the skin and helps break down the excess keratin causing the bumps. Creams containing 10–25% urea are widely available over the counter in the UK and can be particularly effective for people with very dry or rough skin. Unlike some acids, urea is generally very well tolerated, even on sensitive skin.
A beta hydroxy acid (BHA), salicylic acid penetrates into hair follicles and helps dissolve the keratin blockages from within. Studies show around 52% improvement with 5% salicylic acid — making it a solid option, especially for those who find AHAs irritating.
Practical tips:
For some people, over-the-counter products simply don't provide sufficient improvement — particularly for KP that is inflamed, widespread, or accompanied by significant redness. In these cases, prescription-strength treatments or professional procedures may be worth considering.

It's also worth seeing a dermatologist if you're unsure whether you have KP or another condition. Red, bumpy skin can sometimes be mistaken for acne, folliculitis, milia, or contact dermatitis — each of which requires a different treatment approach. A professional assessment means you won't waste time treating the wrong thing.
In the UK, NHS dermatology waiting times can stretch from 8 weeks to well over a year in some areas. If you're dealing with persistent KP — especially if it's affecting your confidence or quality of life — that's a long time to wait for answers.

Managing KP is more of a long-term skin care commitment than a one-time fix. Most people find that with a consistent routine — moisturising daily, exfoliating gently two to three times per week, and choosing the right active ingredients — their skin texture improves considerably within a few months.
It's also worth tracking your triggers. Some people find that:
The psychological impact of KP is often underestimated. While the condition is physically harmless, many people feel self-conscious about the texture and appearance of their skin — particularly in summer when more skin is on show. If KP is affecting your confidence, it's worth seeking professional advice rather than simply trying to hide it.
Keratosis pilaris may be common, but that doesn't mean you have to put up with it. With the right combination of moisturising, exfoliation, and patience — and professional dermatology input when needed — significant improvement is achievable for most people.
