What should you know about KP keratosis pilaris?

The bumps form when keratin, a natural skin protein, builds up around hair follicles. They can feel like fine sandpaper and may be skin-coloured, pink or darker than nearby skin. This is often called chicken skin. Dry weather, friction and naturally dry skin can make the texture more noticeable. Keratosis pilaris is not caused by poor hygiene and it does not spread from person to person.

The appearance can resemble other sources of skin bumps or ingrown hairs, so a clinician may look at the distribution, texture and symptoms before confirming the diagnosis.

Use a gentle cleanser and apply a plain moisturiser soon after bathing, while the skin is still slightly damp. Products containing urea, lactic acid or salicylic acid may soften built-up scale; introduce one active product at a time and stop if burning or marked irritation develops. Avoid harsh scrubs, picking and very hot showers, which can increase redness. A dermatologist can discuss emollient therapy, topical retinoids, or selected procedures such as a chemical peel or laser hair removal when texture remains bothersome.

Arrange a dermatology review if the bumps are painful, pus-filled, rapidly changing, intensely itchy, or spreading in an unusual pattern. Seek prompt medical advice for facial swelling, breathing difficulty, fever, or a rash involving the eyes or mouth. A review is also useful when home care irritates your skin or you are unsure whether the bumps are keratosis pilaris.

Could this be keratosis pilaris rather than another type of skin bump? Which moisturising ingredient suits my skin? How often should I use an exfoliating product? Would a prescription retinoid or an in-clinic option be reasonable for my concern?
