Sugar scrub for keratosis pilaris: what to know

Keratosis pilaris develops when keratin builds around hair follicles, creating small rough bumps often found on the upper arms, thighs, cheeks or buttocks. The bumps may be skin-coloured or red and are usually not dangerous. Scrubbing does not remove the follicular plugging at its source. If bumps are painful, pus-filled, very itchy or centred on hairs, another problem such as ingrown hairs or folliculitis may need consideration.

Use warm rather than hot water, a gentle cleanser and regular moisturising. Apply an [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) product to damp skin; ingredients that soften scale may be more useful than coarse particles. A clinician may consider [Topical Retinoids](/treatments/medical-dermatology/topical-retinoids/) or a [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/) for selected cases. Introduce one active product at a time, stop if burning develops, and protect treated skin from excess sun.

Seek an assessment when the diagnosis is uncertain, the area becomes painful or infected-looking, or home care causes persistent burning. Prompt advice is useful if bumps suddenly spread, bleed, form crusts or interfere with sleep. A clinician can distinguish keratosis pilaris from [Skin Bumps](/symptoms/skin-bumps/) caused by another condition.

Do these bumps fit keratosis pilaris? Which moisturising ingredient should I try? Would a retinoid or peel suit my skin? How should I manage irritation and ingrown hairs?
