What should you know about magnesium and keratosis pilaris?

Keratosis pilaris is a common pattern of small, rough bumps caused by keratin collecting around hair follicles. The bumps often appear on the upper arms, thighs, cheeks, or buttocks and may be skin-coloured or red. It is not caused by poor hygiene. Magnesium supplements or topical magnesium products should not be assumed to clear the plugs, and supplements can be unsuitable for some people or medicines.

Use a gentle cleanser, keep showers comfortably warm rather than hot, and apply an emollient soon after washing. Products containing urea, lactic acid, or salicylic acid may soften roughness when suitable for your skin. Introduce one active product at a time and stop if stinging or marked redness occurs. Do not squeeze or scrub the bumps. A dermatologist may consider topical retinoids, a chemical peel, or laser hair removal in selected situations, particularly when texture, redness, or follicle-related irritation remains troublesome.

Seek an assessment if bumps become painful, pus-filled, suddenly widespread, or very itchy, because folliculitis, allergy, or another condition can look similar. Get advice before taking magnesium for this purpose if you have kidney disease, take regular medicines, or are pregnant. Arrange review when self-care has not helped or the appearance is affecting your confidence.

Ask whether the bumps are keratosis pilaris or ingrown hairs, which moisturiser or active ingredient fits your skin, and whether magnesium has any role in your personal care plan. Discuss irritation risks before a peel or laser procedure.
