Have you ever noticed tiny, rough bumps on your arms, thighs, or cheeks that look like goosebumps and just won’t go away? You’re not alone — it might be something called Keratosis Pilaris (KP), often known as “chicken skin.” It’s completely harmless, but understanding what causes it can help you manage it naturally and confidently.

What Is Keratosis Pilaris?

Keratosis Pilaris happens when keratin, a protein that protects your skin, builds up and blocks your hair follicles. This causes small, hard bumps — sometimes red, white, or flesh-colored — usually on the upper arms, thighs, or buttocks. It’s not an infection or allergy, just your skin reacting to extra keratin.

What Causes It?

Dry skin or lack of moisture
Genetics (it often runs in families)
Skin conditions like eczema
Cold, dry weather that strips natural oils

It’s more common in teens and young adults, but anyone can have it.
