Little red bumps on arms that do not itch

Tiny, rough, evenly spaced bumps on the outer upper arms can fit keratosis pilaris, sometimes called chicken skin. It forms when keratin collects around hair follicles and may feel more noticeable than it looks. A bump centered on a follicle, especially after friction, sweating, or shaving, can instead reflect folliculitis. A clinician may distinguish these by checking whether the surface is rough, whether there are pustules, and whether the area is spreading.

Wash gently with lukewarm water and a fragrance-free cleanser, then apply a plain moisturizer while the skin is still damp. Avoid picking, harsh scrubs, rough gloves, and tight sleeves that rub the area. If the bumps are rough and persistent, ask a clinician or pharmacist whether a moisturizer containing urea, lactic acid, or salicylic acid suits your skin; introduce one product gradually and stop if it stings or becomes inflamed. Keep a simple note of triggers such as heat, exercise, or hair removal.

Arrange a medical review if bumps become painful, warm, swollen, pus-filled, rapidly more numerous, or associated with fever. Seek prompt care for a spreading area of redness, marked tenderness, or red streaking. A non-itchy stable texture is less urgent, but an appointment is sensible when the appearance persists, changes, bleeds, or remains unclear after gentle care.

Ask whether the pattern fits keratosis pilaris or folliculitis, which ingredient is safest for your skin, and how long to try it before reassessment.
