Keratosis Pilaris: What Causes "Chicken Skin" and How to Smooth It

If you've ever felt a patch of tiny, rough bumps on the backs of your arms or your thighs,  sometimes pink, sometimes skin-coloured ,you've met keratosis pilaris. It's one of the most common skin conditions in the world, and one of the most misunderstood. The good news: it's completely harmless. The better news: while there's no permanent cure, the right ingredients and a consistent routine can make a real, visible difference to how smooth your skin feels and looks.

What Is Keratosis Pilaris?

Keratosis pilaris (KP), nicknamed "chicken skin," or "strawberry legs" when it appears on the legs, happens when keratin, a protein that protects your skin, builds up and plugs the opening of a hair follicle. Each plugged follicle becomes a small, hard bump. Multiply that across an area and you get that characteristic sandpapery texture.

It most often appears on the:

• Upper arms (the most common spot)
• Thighs
• Buttocks
• Cheeks (more common in children)

KP is extremely common, tends to run in families, often shows up alongside dry skin or eczema, and frequently flares in winter when the air is drier. Many people find it eases naturally with age. Two things to be clear about: KP is not contagious, and it has nothing to do with poor hygiene. It's simply how some people's follicles behave.

Why Most "Treatments" Disappoint

Here's the single most useful thing to understand: the bumps are caused by a plug. So anything that doesn't address that plug will, at best, make skin feel temporarily softer without changing the texture.

This is why so many people say "I've tried everything and nothing works." Usually what they've tried is a plain moisturiser. Moisturisers matter, they reduce the dryness and redness that make KP look worse, but on their own they don't dissolve the keratin buildup.

Treating KP well means doing two jobs at once: gently exfoliating the plug and supporting the skin barrier so the exfoliation doesn't leave skin red and raw. The best routines combine both.

The Ingredients That Actually Work

Chemical exfoliants — the workhorses

These dissolve the bonds holding dead, plugging cells in place, and they're responsible for real change in texture.

• Glycolic acid — An alpha hydroxy acid (AHA) that lifts away the buildup at the surface of the follicle. It's effective and widely used for body smoothing, and it pairs well with hydrating ingredients that offset any tingling.
• Lactic acid — A gentler AHA that exfoliates and hydrates; a good entry point for sensitive skin.
• Urea — Does double duty as both a keratolytic (breaks down the plug) and a humectant. One of the strongest single ingredients for stubborn KP.
• Salicylic acid — An oil-soluble BHA that gets into the follicle and helps calm redness. A good choice for more inflamed KP.

For most people, a body lotion built around one of these acids, used consistently, is the foundation of an effective routine.

Barrier supporting ingredients — the essential backup

These don't unplug follicles, but they make exfoliation tolerable and reduce the dryness and redness that exaggerate KP's appearance:

• Glycerin, hyaluronic acid, and sodium PCA — humectants that draw and hold water in the skin
• Squalane and plant oils (such as sweet almond and avocado) — soften and seal in moisture
• Soothing botanicals like aloe, chamomile, calendula, and cucumber - help calm visible redness

The most effective products pair an exfoliating active with these soothing ingredients, so you get smoother skin without trading the bumps for irritation.

Where the Body Smoothing Lotion Fits

Our Body Smoothing Lotion is built around exactly this pairing. It uses glycolic acid for gentle daily exfoliation, balanced by a deeply hydrating base — aloe vera, glycerin, hyaluronic acid, sodium PCA, squalane, sweet almond and avocado oils — and a blend of calming botanical extracts including chamomile, calendula, cucumber, and yarrow.

Being straight about what that means: this is a gentle, hydration-forward smoothing lotion, not a heavy-duty acid treatment. That's by design. It's well suited to:

• Everyday maintenance to keep skin smooth and soft
• People newer to exfoliating acids, or with sensitive, easily-irritated skin
• Anyone who finds stronger urea or salicylic-acid treatments too harsh

If your KP is severe or very inflamed, you may want a higher-strength urea or salicylic-acid product (or a chat with a dermatologist) and can use a lotion like this for ongoing hydration and gentle upkeep.

A note on sensitivity: the formula contains a fragrant oil, and because KP often appears alongside eczema-prone or reactive skin, we recommend a quick patch test on a small area first, as you should with any new product.

How to Use It (Without Making Things Worse)

• Be consistent and patient. KP responds to regular use over weeks, not days.
• Don't over-exfoliate. More acid more often isn't better — it causes irritation. Once daily is plenty for most people; every other day if you're starting out.
• Skip harsh scrubbing. Aggressive physical exfoliation irritates KP rather than fixing it. Let the actives work.
• Never pick at the bumps. Picking can cause marks and scarring.
• Mind the sun. AHAs can increase sun sensitivity, so use sunscreen on exposed areas.
• Moisturise consistently, especially in dry weather.

When to See a Dermatologist

KP is benign, so professional treatment is optional,  but it's worth seeing a dermatologist if the bumps are very inflamed or itchy, if over-the-counter products haven't helped after consistent use, if you're unsure whether it's actually KP, or if you'd like prescription-strength options.

The Bottom Line

Keratosis pilaris is common, harmless, and manageable. The texture comes from a keratin plug, so the ingredients that make a difference are the ones that gently exfoliate it like, glycolic acid — paired with hydrating, soothing ingredients that keep skin calm. Used consistently, that combination is what turns rough, bumpy skin smooth.

Our Body Smoothing Lotion is designed around that approach for gentle, everyday results.
