Keratosis pilaris — often called "chicken skin" — is a very common, harmless condition where tiny rough bumps form on the upper arms, thighs, and cheeks. It's a buildup of keratin plugging the hair follicles, not dirt or acne.
What keratosis pilaris actually is
Excess keratin traps around the follicle, creating small, sometimes reddish bumps with a sandpaper feel. It's genetic, tends to run in families, and often improves with age and in humid weather.
What smooths it
- Chemical exfoliants: lactic acid, urea, or salicylic acid dissolve the keratin plugs — far better than scrubbing.
- Rich moisturizer: daily, to soften and reduce roughness.
What to avoid
Harsh physical scrubbing and picking make it redder and can scar. Keratosis pilaris can't be cured, but consistent gentle exfoliation plus moisture keeps it smooth and far less visible. Hot showers dry skin and worsen it, so keep water lukewarm.
