How to help prevent keratosis pilaris

Keratosis pilaris happens when keratin, a protein in the outer skin layer, plugs hair follicles. It often feels like small, rough bumps on the upper arms, thighs, cheeks, or buttocks. Dryness can make the texture more noticeable, while scrubbing, picking, and close shaving may inflame follicles or create ingrown hairs.

Keep showers warm rather than very hot and use a mild cleanser. Apply an emollient soon after washing, while the skin is still slightly damp. Products containing urea, lactic acid, or salicylic acid may smooth plugged follicles, but introduce one active product at a time and stop if burning or marked redness develops. Avoid rough gloves, vigorous scrubs, and picking. If hair removal worsens the bumps, use a gentle method and discuss alternatives such as laser hair removal with a qualified clinician. A dermatologist may consider a topical retinoid or a chemical peel when home care is not enough.

Book a review if bumps are painful, pus-filled, rapidly changing, intensely itchy, or spreading in an unusual pattern. Persistent redness or dark marks after irritation also deserve assessment. A clinician can check whether the problem is keratosis pilaris, folliculitis, acne, or another cause of skin bumps, then match treatment to your skin sensitivity.

Ask which moisturiser or exfoliating ingredient suits your skin, how often to use it, and whether shaving is contributing to ingrown hairs. Ask before using a topical retinoid if you are pregnant, planning pregnancy, or breastfeeding.
