Keratosis Pilaris: Causes, Treatment and Skin Care

Keratosis pilaris is a harmless condition caused by keratin blocking hair follicles. It commonly produces small rough bumps on the upper arms, thighs, cheeks or buttocks.

Appearance and triggers The bumps may be skin-coloured, red or brown and can feel like sandpaper. Dry weather, eczema and friction may make them more noticeable. The condition is not contagious.

Skin care Use lukewarm water, short showers and a gentle cleanser. Apply moisturiser immediately after bathing. Products containing urea, lactic acid, salicylic acid or a retinoid may gradually smooth the skin, but they can irritate if introduced too quickly.

Treatment expectations Keratosis pilaris often improves with age but may recur when treatment stops. Scrubbing, picking and aggressive extraction can increase inflammation and dark marks. Laser treatment may be considered for persistent redness or hair-related irritation in selected patients.

When to seek advice See a dermatologist when the diagnosis is uncertain, the skin is very inflamed or itchy, or pigmentation and scarring are developing. Pregnancy and sensitive skin affect which active ingredients are appropriate.
