Keratosis pilaris white bumps: what to know

Keratosis pilaris forms when keratin blocks the opening of a hair follicle. The plug can look white or pale, while the skin around it may be pink, brown, or close to your natural skin colour. The surface often feels like fine grit or sandpaper. Upper arms and thighs are frequent locations, but the cheeks and buttocks can also be affected.

The condition is not caused by dirt and cannot be scrubbed away safely. White bumps that are sore, hot, swollen, crusted, or draining may reflect folliculitis or another problem instead. Compare the pattern with information about [Skin Bumps](/symptoms/skin-bumps/) and [Ingrown Hairs](/symptoms/ingrown-hairs/) if the diagnosis is uncertain.

Wash gently, pat dry, and apply a moisturiser soon afterwards. Choose loose clothing where friction is a problem, and resist scratching or extracting individual plugs. Products containing urea or other smoothing ingredients may be useful, but introduce one change at a time so irritation is easier to identify. [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) offers a barrier-focused option.

For persistent texture, a dermatologist can discuss [Topical Retinoids](/treatments/medical-dermatology/topical-retinoids/), a [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/), or other treatments. If hair removal is contributing to irritation, ask whether [Laser Hair Removal](/treatments/laser-and-energy/laser-hair-removal/) is suitable for your skin and hair pattern.

Arrange medical review if the bumps spread quickly, become painful, itch intensely, form blisters, or produce pus. Also seek advice if a routine causes persistent burning or if the bumps do not match the usual follicular pattern. Prompt assessment is appropriate for fever or rapidly increasing swelling alongside a skin change.

Does this look like keratosis pilaris on my skin tone? Which product should I start with, and how often? Could shaving, friction, or another condition be causing the bumps? How long should I try home care before changing the plan?
