What should you know about keratosis pilaris dry skin?

Small plugs of keratin can collect around hair follicles, giving the skin a sandpaper-like surface. The upper arms, thighs, cheeks and buttocks are frequent sites, although other areas can be involved. Dry air, hot showers, harsh cleansers and friction may make roughness or itch more noticeable. These bumps are not the same as an infection, and squeezing them can cause irritation or dark marks.

Use a gentle cleanser and keep showers comfortably warm rather than hot. Pat the skin dry, then apply a fragrance-free moisturiser while it is still slightly damp. Products with urea, lactic acid or salicylic acid may soften thick surface skin; introduce one active product gradually and stop if burning or marked redness develops. A dermatologist can advise whether emollient therapy or a topical retinoid suits your skin. Avoid rough scrubs, picking and tight clothing over the bumps.

Arrange a dermatology assessment if the area becomes painful, hot, swollen, crusted or pus-filled, or if the appearance changes quickly. Seek advice when persistent itch, bleeding, widespread redness or repeated irritation disrupts sleep or daily activities. A clinician can check whether another rash is present alongside keratosis pilaris.
