🤔 What is Keratosis Pilaris?
Keratosis pilaris (KP) — often called "chicken skin" or "strawberry skin" — is a common, harmless skin condition that causes small, rough bumps to appear on the skin. It occurs when keratin (a protein in skin) builds up and blocks hair follicles.
Key characteristics:
- Small bumps — Usually painless, rough to the touch
- Appearance — Similar to goosebumps or chicken skin
- Color — Can be white, red, or brown depending on skin tone
- Location — Most common on upper arms, thighs, buttocks, and sometimes face
- Worse in winter — Dry skin makes it more noticeable
📍 Location-Specific Guide
Keratosis pilaris can appear on various parts of the body. Each location may present slightly different characteristics and require specific management approaches.
Keratosis Pilaris on Arms
Most common location — upper arms are typically affected first. Bumps are rough, often red or brown, and may be accompanied by dry, scaly skin.
Keratosis Pilaris on Legs
Common on thighs and sometimes shins. May be more noticeable after shaving. Bumps can be more irritated due to friction from clothing.
Keratosis Pilaris on Face
Often appears on cheeks, especially in children. Can be mistaken for acne. Typically presents as rough, red bumps that may be slightly inflamed.
Keratosis Pilaris on Cheeks
Common in children and adolescents. Bumps are usually small, red, and rough. May be worse in dry weather and improve with moisturizing.

Keratosis Pilaris on Feet
Rare but can appear on the tops of feet. Bumps may be more prominent in dry conditions.
