Keratosis pilaris: the skin condition affecting 40% of adults
Keratosis pilaris (KP) is a common, autosomal-dominant, genetic condition of the skin's hair follicles characterized by the appearance of possibly itchy, small, gooseflesh-like bumps. The condition affects an estimated 40% of adults and 50-80% of adolescents, though it's often so mild that people don't realise they have it.
These small, rough bumps most commonly appear on the outer upper arms and thighs, but can show up anywhere on the body except hairless skin (like palms and soles). While the bumps themselves are rarely itchy or irritated, they can knock confidence. Many people with KP cover affected areas to avoid embarrassment.
Three types of keratosis pilaris
KP comes in several forms, each with distinct characteristics:
Keratosis Pilaris Rubra — Red, inflamed bumps that can appear on arms, legs, and other areas. This type shows more visible irritation than other forms.
Keratosis Pilaris Alba — Rough, bumpy skin without redness or irritation. This is the classic "chicken skin" texture.
Keratosis Pilaris Rubra Faceii — A red rash appearing specifically on the cheeks, often mistaken for acne or rosacea.
The science behind the bumps
Those characteristic bumps form when keratin, the protein that protects your skin, builds up and blocks hair follicles. A genetic mutation in filaggrin, the protein that maintains your skin barrier, causes this buildup. When filaggrin doesn't function properly, your skin produces excess keratin.
This keratin combines with dead skin cells to create plugs in the follicles, resulting in tiny raised bumps. When hair gets trapped within these blocked follicles, the bumps can appear red rather than white. Seasonal variation is sometimes described, with improvement of symptoms in summer months. Dry skin in winter tends to worsen symptoms.
Natural approaches that work
While there's no cure for KP, you can significantly improve its appearance with consistent care. The key is combining gentle exfoliation with serious hydration.
Start with exfoliation
Exfoliation may be done physically or chemically; both methods smooth the skin surface and flatten the bumps. Exfoliants do not relieve the redness or itching that may be associated with keratosis pilaris. You can slough off these dead cells gently with a loofah, buff puff, or rough washcloth. Avoid scrubbing your skin, which tends to irritate the skin and worsen keratosis pilaris.
For a natural approach, try mixing fine oatmeal with Manuka honey (look for a high UMF rating, which indicates stronger antibacterial properties). The oatmeal gently buffs away dead skin while Manuka's anti-inflammatory properties calm any irritation. Exfoliating 2-3 times per week is generally recommended for treating keratosis pilaris. This frequency helps remove dead skin cells and keratin buildup without over-exfoliating, which can irritate the skin.
Follow with targeted hydration
After exfoliation, always moisturise. Our Soothing Body Cream delivers anti-inflammatory botanicals along with intense hydration. The calendula soothes irritated skin while comfrey supports healing.
For an extra boost, add a few drops of Rosehip BioRegenerate Oil to your body cream before applying. The oil's high concentration of regenerative sterols encourages cell turnover, helping prevent the buildup of dead skin cells that creates those bumps in the first place. Our CO2 extraction process preserves 700% more active compounds than standard rosehip oils, making it particularly effective for skin renewal.
Chemical exfoliation: the science-backed option
You have two exfoliation options: physical and chemical. Chemical exfoliants work by dissolving the bonds between dead skin cells. Look for products containing: Urea, lactic acid, salicylic acid, or glycolic acid. Topical preparations containing lactic acid, ammonium lactate, salicylic acid, urea, or a combination of these ingredients work by dissolving the bonds between dead skin cells.
These ingredients penetrate deeper than physical exfoliation to break down keratin plugs within the pores. Start slowly with any chemical exfoliant. Reduce your use of exfoliants if your symptoms worsen or if you experience dryness, redness, rash, or irritation.
Daily habits that help
Beyond targeted treatments, simple changes to your routine can prevent flare-ups:
Keep showers short and lukewarm. Hot water strips natural oils and worsens dryness. To prevent drying your skin, take a short (20 minutes or less) bath or shower and use warm rather than hot water. Also, limit bathing to once a day.
Switch to fragrance-free, gentle cleansers. Bar soap can dry your skin. Look for cream or oil-based formulas instead.
Run a humidifier when indoor air is dry. Central heating and air conditioning both zap moisture from the air and your skin.
Pat skin dry after bathing, don't rub. Apply moisturiser while skin is still slightly damp to lock in hydration.
Shaving or waxing skin with keratosis pilaris can cause more bumps. Laser hair removal can remove the hair without causing a flare-up.
When to see a dermatologist
While KP is harmless and often improves with age, professional help might be worth considering if home treatments aren't working after several months of consistent use. If home treatments haven't improved your KP after several months of consistent use, a dermatologist can prescribe stronger treatments. Because you cannot cure keratosis pilaris, you'll need to follow a maintenance plan.
A dermatologist can prescribe stronger treatments or recommend professional procedures. Fractional carbon dioxide lasers and Nd:YAG laser therapies are also effective for stubborn cases, particularly when redness is a concern.
Living with keratosis pilaris
Remember, KP does not bear any known, long-term health implications, nor is it associated with increased mortality or morbidity. While it can't be cured, it can absolutely be managed. Many people find their KP improves significantly in their twenties and thirties.
The most important thing? Consistency. Choose a routine you can stick with. Regular exfoliation paired with dedicated moisturising will keep bumps at bay and skin feeling smoother. With the right approach, KP doesn't have to dictate your wardrobe choices or dent your confidence.
Frequently Asked Questions
What causes keratosis pilaris?
Keratosis pilaris is caused by a genetic mutation in filaggrin, the protein responsible for maintaining your skin barrier. When filaggrin doesn't function properly, your skin produces excess keratin, which combines with dead skin cells to create plugs in the hair follicles, resulting in those characteristic small, rough bumps.
How often should I exfoliate if I have keratosis pilaris?
Exfoliating 2-3 times per week is the sweet spot. This frequency removes dead skin cells and keratin buildup without overdoing it. Gentle is the key word here: a loofah, buff puff, or a homemade mix of fine oatmeal and high-UMF Manuka honey all work well. Avoid scrubbing, which irritates the skin and can actually make KP worse.
Which Pai products help with keratosis pilaris?
The Soothing Body Cream delivers anti-inflammatory botanicals like calendula and comfrey alongside intense hydration. For extra results, mix a few drops of Rosehip BioRegenerate Oil into the cream before applying. The oil's high concentration of regenerative sterols encourages cell turnover, helping prevent the dead skin buildup that creates bumps. Pai's CO2 extraction process preserves 700% more active compounds than standard rosehip oils.
Does keratosis pilaris get worse in winter?
It often does. Dry winter air and central heating strip moisture from your skin, which worsens symptoms. Keeping showers short and lukewarm, running a humidifier, and moisturising while skin is still slightly damp can all help counteract seasonal flare-ups. Many people notice their KP improves naturally in summer months.
Can keratosis pilaris be cured, and when should I see a dermatologist?
There's no cure for KP, but consistent care can significantly improve its appearance, and many people find it improves naturally in their twenties and thirties. If home treatments haven't worked after several months, a dermatologist can prescribe stronger options or recommend procedures like fractional carbon dioxide or Nd:YAG laser therapy, particularly when redness is a concern.
