What should you know about extreme keratosis pilaris?

Keratosis pilaris develops when keratin builds up around hair follicles, creating small rough bumps commonly on the upper arms, thighs, cheeks, or buttocks. A severe-feeling flare may be widespread, itchy, red, or emotionally distressing. Scratching, picking, harsh scrubs, and close shaving can inflame the follicles and make the texture more noticeable. Similar bumps can be ingrown hairs, folliculitis, or another rash, so pus, marked pain, or sudden change deserves an examination.

Use short lukewarm showers, a fragrance-free cleanser, and an emollient soon after bathing. Apply products consistently rather than scrubbing harder. A clinician may suggest an exfoliating moisturiser, topical retinoid, or another plan suited to your skin. Chemical peels or laser hair removal may be considered in selected cases, but they can irritate active inflammation and should be planned with a qualified professional. Do not squeeze the bumps.

Arrange a dermatology review if the bumps are painful, draining, rapidly spreading, leaving dark marks or scars, or failing to improve with gentle moisturising. Seek prompt care for fever, warmth, rapidly increasing redness, or a tender area that suggests infection. Ask for assessment before treating bumps on the face, in children, or during pregnancy.

Are these bumps keratosis pilaris or ingrown hairs? Which moisturiser or active ingredient fits my skin? Would a retinoid, peel, or laser approach be appropriate, and how should irritation be managed?
