When to worry about skin bumps with keratosis pilaris

Keratosis pilaris creates many small, rough bumps around hair follicles, commonly on the outer upper arms, thighs, cheeks, or buttocks. The skin may feel like sandpaper and can look red, brown, or close to its natural colour. Dryness and seasonal changes can make the texture more noticeable.

These bumps are usually not painful or filled with pus. A single lesion that grows quickly, bleeds, ulcerates, becomes very tender, or looks unlike the surrounding pattern should be checked because another condition may be present.

Use a short, lukewarm wash and apply a plain moisturiser while the skin is still slightly damp. Products containing a keratolytic ingredient may smooth roughness, but introduce them gradually and stop if burning or marked irritation develops. Do not pick, scratch, or scrub hard; these can worsen redness and leave marks.

If the texture bothers you despite gentle care, a dermatologist can confirm the diagnosis and discuss options appropriate for your skin, age, and the affected body area. Improvement often requires consistent care rather than forceful exfoliation.

Book an assessment when bumps are painful, hot, swollen, rapidly changing, crusted, bleeding, or draining pus, or when the rash spreads in an unfamiliar pattern. Seek advice if itching is severe, sleep is disturbed, or treatment causes persistent burning. Prompt review is sensible when the diagnosis is uncertain.

Ask whether the distribution and texture fit keratosis pilaris, which moisturiser or exfoliating ingredient is suitable, and how often to use it. Ask how to tell irritation, folliculitis, or infection from your usual bumps.
