What should you know about topical exfoliants for keratosis pilaris?

Keratosis pilaris, sometimes called chicken skin, forms when keratin collects around hair follicles. Products containing exfoliating acids can help release this material from the follicle opening and smooth the surface. They do not remove the underlying tendency, so roughness or bumps may return when care stops. Irritation can make redness more noticeable, especially on sensitive or darker skin, so a mild product and a small test area are sensible starting points.

Apply the product to clean, dry skin as directed on its label, then follow with a bland moisturiser if the area feels dry. Avoid combining several strong exfoliants, vigorous scrubbing, or application to cracked, sunburned, or freshly shaved skin. A clinician can help choose between an exfoliating lotion, an emollient, or a topical retinoid when bumps persist. Chemical peels and laser hair removal are separate options that need professional assessment.

Arrange a dermatology review if bumps are painful, pus-filled, rapidly changing, very itchy, or spreading beyond your usual pattern. Stop the product and seek advice for marked burning, swelling, blistering, or a rash that continues after washing it off. Skin bumps or ingrown hairs may have other causes and may need a different approach.

Ask which exfoliating ingredient suits your skin, how often to apply it, and whether another condition is causing the bumps. Discuss how to protect the area from irritation and when to consider professional treatment.
