What should you know about chicken spots on arms?

Small rough bumps clustered on the outer upper arms often fit keratosis pilaris, while red or pus-tipped bumps around hairs may fit folliculitis. Pimples can be red, swollen, or blocked with a white or dark centre. Sweat, friction, shaving, tight sleeves, and oily products can all aggravate follicle-based spots.

The same-looking spot can have different causes, and a spot on the arm does not by itself establish acne or another diagnosis. Note whether the area is itchy or painful, whether new products or hair removal preceded it, and whether marks remain after the bumps settle.

Wash gently after sweating, wear breathable clothing, and avoid rubbing or picking the area. Choose non-comedogenic body products when blocked pores are a concern. A pharmacist or clinician can help select an acne or follicle-care product; use one new active at a time and protect exposed skin from sunlight to reduce lingering discolouration.

If bumps follow shaving, use a clean razor, shave in the direction of hair growth, and allow irritated skin to recover. LED Light Therapy may be discussed for selected inflammatory skin concerns, but it does not replace diagnosis or care for infection.

Seek review when spots are rapidly multiplying, painful, hot, draining, deeply swollen, or leaving scars, or when they do not improve with gentle care. Fever, red streaking, or feeling unwell needs prompt medical attention. A clinician may distinguish [Acne](/conditions/acne/), [Folliculitis](/conditions/folliculitis/), or another condition by examining the lesions.

Ask whether the pattern is acne, folliculitis, or keratosis pilaris; whether shaving or products are contributing; and which treatment is suitable for your skin and any marks left behind.
