What does keratosis pilaris look like?

The bumps form when keratin, a protein in the outer skin layer, collects around hair follicles. The surface can feel like fine sandpaper, and nearby skin may be dry. Upper arms, thighs, cheeks, and buttocks are common sites, although the pattern varies between people. It is often called chicken skin. Unlike an ingrown hair, each bump usually follows a follicle and does not contain a trapped curved hair. Colour can be more noticeable after irritation or scratching.

Use a gentle cleanser and apply an unscented moisturiser while the skin is still slightly damp. Products containing urea, lactic acid, or salicylic acid may soften rough plugs when used as directed. Introduce one active product at a time and stop if burning or marked redness develops. Scrubbing, picking, and very hot showers can irritate the follicles. A dermatologist can discuss [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) or [Topical Retinoids](/treatments/medical-dermatology/topical-retinoids/) when basic care is not enough.

Arrange an assessment if bumps become painful, warm, rapidly swollen, crusted, or filled with pus, because those features are less typical of uncomplicated keratosis pilaris. Seek advice too if the rash is spreading quickly, intensely itchy, or different on one side. A clinician can compare it with [Skin Bumps](/symptoms/skin-bumps/) and [Ingrown Hairs](/symptoms/ingrown-hairs/) before recommending treatment.

Could these bumps be keratosis pilaris or another follicle condition? Which ingredient suits my skin tone and sensitivity? How should I combine moisturiser with treatment, and what should make me stop?
