What should you know about exfoliating keratosis pilaris?

Keratosis pilaris happens when keratin collects around hair follicles, producing small rough bumps commonly on the upper arms, thighs, cheeks, or buttocks. It is not the same as trapped hairs, although both can look like small bumps. Dry air, friction, and harsh washing may make the texture more noticeable.

The aim of exfoliation is to loosen surface buildup gradually, not to strip the skin. See [Keratosis Pilaris](/conditions/keratosis-pilaris/) and [Skin Bumps](/symptoms/skin-bumps/) for related descriptions.

Keep showers comfortably warm rather than hot, use a mild cleanser, and apply a moisturiser soon after bathing. A clinician may recommend a product containing an exfoliating ingredient or a topical retinoid, introduced gradually to limit dryness. Avoid rough gloves, picking, and repeated scrubbing. If redness, burning, or cracking develops, stop the irritating product and simplify the routine. [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) can support the skin barrier.

Arrange an assessment if bumps are painful, pus-filled, rapidly changing, intensely itchy, or confined to an unusual area. Seek advice when home care causes persistent burning or when the texture is not improving, because folliculitis, eczema, or another condition may look similar.

Ask which ingredient and schedule fit your skin, whether [Topical Retinoids](/treatments/medical-dermatology/topical-retinoids/) are suitable, and how to manage irritation. For persistent texture, ask whether a [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/) or another procedure is appropriate.
