Benign Growths & Cysts
Keratosis Pilaris
KP; "chicken skin"
Very common, especially in youth
No — you cannot catch it or spread it
Harmless; manageable, often improves with age
What Is It?
Keratosis pilaris is a very common, harmless condition that causes small, rough bumps, usually on the upper arms, thighs, cheeks, or buttocks. The skin can feel like sandpaper or look like permanent "goosebumps." It's not painful or dangerous and often improves with age.
Signs & Symptoms
-
Small, rough bumps that feel like sandpaper
-
Usually on upper arms, thighs, cheeks, or buttocks
-
Skin-colored, red, or brown bumps
-
Usually not itchy or painful
-
Often drier and more noticeable in winter
Why Does It Happen?
KP happens when keratin (a protein in skin) builds up and plugs the hair follicles, creating tiny rough bumps. It tends to run in families and is more noticeable in people with dry skin or eczema, and in dry winter months. It is NOT an infection, NOT contagious, and NOT caused by poor hygiene.
Treatment Options
KP is harmless, so treatment is optional and focused on smoothing the skin. Consistent moisturizing and gentle exfoliation help most; results fade if you stop.
MOISTURIZE
Thick creams keep skin hydrated and soften bumps.
EXFOLIATING CREAMS
Lotions with urea, lactic, salicylic, or glycolic acid smooth the skin.
GENTLE CARE
Avoid scrubbing or picking, which irritates the skin.
PATIENCE
It's harmless and often improves with age.
Tips for Managing It at Home
-
Moisturize daily, especially after bathing
-
Use lukewarm (not hot) water and gentle cleansers
-
Don't scrub or pick — it worsens redness
-
Be consistent; improvement is gradual and reverses if you stop
