Keratosis Pilaris (Chicken Skin): Symptoms, Causes & UK Treatment Guide

Keratosis pilaris, frequently referred to as 'chicken skin' or 'gooseflesh' skin, is a very common and entirely harmless skin condition. It presents as numerous small, rough, and sometimes red or brown bumps on the skin's surface. While it can occur anywhere there are hair follicles, it is most commonly found on the back of the upper arms, the front of the thighs, and occasionally the buttocks or face.

According to NHS guidance, keratosis pilaris is not contagious and cannot be spread from person to person. It is often described as a 'variant of normal skin' rather than a disease. It affects roughly 50 to 70% of adolescents and around 40% of adults in the UK. Many people find that the condition improves as they get older, often fading significantly by their 30s.

The primary symptom of keratosis pilaris is the appearance of tiny, painless bumps. The skin in the affected area often feels like coarse sandpaper. Key characteristics include:

• Small, hard bumps: These are usually skin-coloured, but may appear red on light skin or dark brown/black on darker skin tones.
• Lack of irritation: Unlike eczema or hives, the bumps are rarely itchy or painful.
• Dryness: The affected area is often notably dry and may feel slightly rougher in the winter months when humidity is lower.
• Location: Symmetry is common, appearing on both arms or both legs simultaneously.

It is important to distinguish this from other conditions like folliculitis (which is usually painful or pus-filled) or acne. If the bumps are causing significant emotional distress or if the surrounding skin is becoming increasingly inflamed, seeking professional advice is recommended.

Keratosis pilaris occurs when your body produces too much keratin, a structural protein found in the skin, hair, and nails. This excess keratin forms a plug at the opening of the hair follicle, trapping the hair inside and causing the characteristic raised bump.

The exact reason why keratin builds up is not fully understood, but several factors are known to play a role:

• Genetics: It is known to run in families. If one parent has it, there is a high likelihood their children will too.
• Associated Conditions: It is more common in individuals who suffer from atopic dermatitis (eczema), asthma, or hay fever.
• Skin Type: People with naturally dry skin are more prone to developing the condition.
• Climate: Symptoms often worsen in the UK during winter due to dry air and central heating, which dehydrates the skin.

While there is no permanent 'cure' for keratosis pilaris, its appearance can be significantly improved with a consistent skincare routine. NICE (National Institute for Health and Care Excellence) suggests that the mainstay of treatment involves skin softening and exfoliation.

Chemical Exfoliants

Rather than using harsh physical scrubs, which can irritate the skin, 'chemical' exfoliants help dissolve the keratin plugs. Look for over-the-counter creams containing:

• Urea: This acts as a humectant (drawing moisture into the skin) and a keratolytic (breaking down keratin).
• Salicylic Acid: A beta-hydroxy acid that penetrates the follicle to clear out dead skin cells.
• Lactic Acid: An alpha-hydroxy acid that gently exfoliates while hydrating.

Moisturising and Lifestyle

Keeping the skin hydrated is essential. Use 'emollient' creams several times a day. Avoid long, hot showers as these strip the skin of natural oils; instead, opt for lukewarm water and use soap-free cleansers. Pat the skin dry gently rather than rubbing it with a towel.

Many patients find that despite trying various high-street lotions, their keratosis pilaris remains stubborn or causes them to feel self-conscious. You should consider booking a consultation with an online GP if:

• The bumps are becoming red, hot, or painful, which may indicate a secondary infection.
• The condition is causing significant psychological distress or affecting your confidence.
• You are unsure of the diagnosis and want to rule out other skin conditions like psoriasis or lichen pilaris.
• Standard over-the-counter treatments have failed to show any improvement after 6 to 8 weeks.

Speaking to an online doctor in the UK allows you to upload high-quality photographs and receive a professional assessment from the comfort of home. A GP can provide advice on more potent prescription-strength creams, such as topical retinoids, which help promote cell turnover and prevent the follicles from clogging.

Keratosis pilaris is a chronic condition, meaning it can persist for years. However, the outlook is very positive. Most people find that the bumps naturally smooth out as they reach adulthood. In the meantime, the condition is entirely manageable. Consistency is the most important factor—once you stop using the recommended moisturisers or exfoliants, the keratin buildup usually returns. Embracing a long-term, gentle skincare habit is the best way to maintain smooth skin.
