Keratosis Pilaris or "Chicken Skin"

What is Keratosis Pilaris?

Keratosis pilaris (KP) is a common skin condition affecting between 50% and 80% of children and adolescents and around 40% of adults. It is characterized by the keratinization of skin cells around hair follicles, causing small, hardened bumps. Often described as “chicken skin” or “goosebumps,” KP typically appears on the arms, thighs, cheeks, and torso. It commonly affects young children and adolescents but may resolve or improve as individuals age.

Common Symptoms of Keratosis Pilaris:

• Small, hard bumps on upper arms, thighs, buttocks, or cheeks

• Dry, scaly patches over bumps

• Rough, sandpaper-like skin texture

• Appearance resembling goosebumps or chicken skin

• Bumps typically located near hair follicles

• Bumps that may be red, pale, or slightly different from natural skin tone

• Possible dryness or mild itch around affected skin

• Condition often worsens in cold, dry climates

Causes of Keratosis Pilaris:

While no single cause is identified, KP is considered a genetic skin condition, frequently occurring in those with a family history. It commonly coexists with dry skin conditions (xerosis, atopic dermatitis) and systemic concerns such as asthma or allergies. Seasonal flare-ups during dry winter months are common, with improvements often seen in humid climates. KP affects all genders and races equally, typically beginning in infancy, childhood, or adolescence.

Prevention and Treatment Tips:

While KP is harmless and treatment is optional, you can manage symptoms effectively:

Exfoliate:

• Use a gentle loofah or washcloth with moisturizing cleansers daily.

• Avoid aggressive scrubbing to prevent irritation.

Use a Keratolytic:

• Choose skincare products containing key OTC ingredients known to manage KP effectively:

  
  

  • Alpha hydroxy acid (AHA)

  • Glycolic acid

  • Lactic acid

  • Salicylic acid

  • Urea

  • Ceramides

  • Retinoids

Short Showers:

• Limit shower/bath duration and avoid hot water to prevent drying of the skin.

Hydrate:

• Apply moisturizers immediately after bathing, preferring creams over lotions.

• Use moisturizing products containing lactic acid, urea, salicylic acid, or ceramides 2-3 times daily.

Humidify:

• Use a humidifier at home, especially in dry winter months.

  
  

Careful Hair Removal:

• Exercise caution with shaving or waxing KP-prone areas.

• Consider alternative methods such as laser hair removal.

Maintenance:

• Regularly exfoliate and moisturize multiple times per week.
