Keratosis pilaris in arms

The bumps commonly sit on the outer upper arms and may resemble permanent gooseflesh. They can be skin-coloured, pink, red, brown, or darker than nearby skin. Dry weather, friction from clothing, and hot showers can make the surface feel rougher. Keratosis pilaris is different from ingrown hairs, which form when a growing hair curls back into the skin.

A clinician can examine the follicle pattern and ask about itch, pain, shaving, and new products. Skin bumps that are pus-filled, very tender, or spreading may need another explanation.

Keep showers warm rather than hot, use a mild cleanser, and apply an emollient soon after washing. A lotion with urea, lactic acid, or salicylic acid may loosen built-up keratin; use it gradually and stop if the skin becomes raw. Scrubbing with a rough mitt or squeezing each bump can prolong redness and marks.

If texture remains troublesome, a dermatologist may consider topical retinoids, a chemical peel, or laser hair removal when unwanted hair and follicle irritation contribute. These options need individual assessment, particularly for sensitive or pigment-prone skin.

Book a medical review if bumps begin suddenly, itch intensely, ooze, crust, become painful, or spread beyond the usual outer-arm pattern. Seek prompt care for rapidly increasing swelling, warmth, or fever. A review is also sensible when several weeks of gentle care have not helped, because folliculitis, eczema, and other rashes can look similar.

Ask which moisturising ingredient fits your skin, how often to use an exfoliating lotion, whether any current medicine is drying your arms, and how to reduce marks after inflammation. If you shave, ask whether changing technique or considering laser hair removal would reduce follicle irritation.
