Keratosis Pilaris: Causes, Symptoms, and Treatment

What is it? #

Keratosis pilaris (KP) is a harmless skin condition that causes small, rough bumps to appear, often on the upper arms, thighs, cheeks, or buttocks. These bumps are caused by a buildup of keratin, a protein that protects the skin. In KP, keratin plugs the hair follicles, leading to the characteristic bumps.  

Causes: #

The exact cause of Keratosis pilaris (KP) is unknown, but it is thought to be related to genetics and dry skin. It’s not contagious.  

Symptoms: #

• Small, rough bumps on the skin  
• Dry, sandpaper-like skin texture  
• Itching (sometimes)  
• Bumps may be skin-colored, red, or slightly brown  

Treatment: #

KP often improves with age and sometimes clears up completely.

While there’s no cure, the following can help manage symptoms:

• Moisturizers: Applying moisturizers regularly helps keep the skin hydrated and can improve its appearance.  
• Exfoliation: Gentle exfoliation can help remove dead skin cells.  
• Topical creams: Certain creams containing ingredients like urea, lactic acid, or salicylic acid can help soften the bumps.  

When to see a doctor: #

If home treatments aren’t effective or the condition is bothering you, consult a dermatologist. They can recommend stronger treatments or rule out other skin conditions.  

Key takeaways: #

• KP is a common, harmless skin condition.  
• It’s often caused by a buildup of keratin in hair follicles.  
• Moisturizers and exfoliation can help manage symptoms.  
• Consult a dermatologist if home treatments aren’t effective.
