Microdermabrasion for keratosis pilaris: what to know

Keratosis pilaris is a common condition in which keratin collects around hair follicles, creating small rough bumps that often appear on the upper arms, thighs, cheeks or buttocks. Dryness can make the texture more noticeable. Microdermabrasion can lift superficial scale and briefly smooth the surface, but friction may irritate already inflamed bumps and it does not change the tendency to form plugs.

A diagnosis matters because similar-looking bumps can reflect folliculitis, acne or ingrown hairs. The right plan depends on whether the skin is mainly rough, itchy, red or tender.

Use a gentle cleanser and moisturiser consistently, and avoid picking or vigorous scrubbing. A clinician may discuss [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) or [Topical Retinoids](/treatments/medical-dermatology/topical-retinoids/) when appropriate. Other options can include a [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/) or, for selected hair-related concerns, [Laser Hair Removal](/treatments/laser-and-energy/laser-hair-removal/). Learn more about [Keratosis Pilaris](/conditions/keratosis-pilaris/) and distinguish it from [Skin Bumps](/symptoms/skin-bumps/) or [Ingrown Hairs](/symptoms/ingrown-hairs/).

Arrange an examination if bumps are painful, pus-filled, rapidly spreading, intensely itchy or associated with fever, because those features may need a different assessment. After exfoliation, report blistering, marked burning, worsening redness or persistent colour change. Seek urgent care for facial swelling with breathing difficulty.

Do these bumps fit keratosis pilaris or another follicle condition? Is my skin too inflamed for abrasion today? Which moisturiser or active ingredient should I try first? How will we tell irritation from an infection or ingrown hair?
