Keratosis Pilaris

Keratosis pilaris is a very common, harmless skin condition that produces small, rough bumps, often described as resembling goosebumps or the texture of sandpaper. It typically appears on the upper arms, thighs, buttocks and sometimes the cheeks.

The bumps form when keratin, the protein that makes up the outer skin, builds up and plugs the opening of hair follicles. Each plug traps the developing hair and creates a small raised bump, sometimes with mild redness around it. The condition is not caused by poor hygiene and is not contagious; it often runs in families and is associated with dry skin, tending to be more noticeable in winter or in low humidity. Many people find it improves gradually with age.

Keratosis pilaris cannot be permanently cured, but its appearance can usually be softened with consistent care focused on hydration and gentle exfoliation.

• Regular moisturising, especially with richer body lotions, helps counter the dryness that makes bumps more prominent.
• Ingredients that soften and dissolve built-up keratin, such as urea, lactic acid and other keratolytics, are commonly used to smooth texture over time.
• Aggressive scrubbing tends to irritate rather than help, so gentle, steady application is preferred.

Results are gradual and maintenance-dependent, meaning bumps often return if care stops. If patches become inflamed, itchy or distressing, a dermatologist can suggest additional options.
