Keratosis pilaris is a skin condition that usually occurs in children.
Characterized by dry skin areas with tiny bumps, Keratosis pilaris is both common and harmless. These patchy areas usually occur on the upper arms, thighs, cheeks, and buttocks. Dry weather can make them worse.
Keratosis pilaris is so named because the condition is the result of a keratin buildup. Keratin is a protein that protects the skin from infection, but with keratosis pilaris, the keratin builds up, covers hair follicle openings, and causes the tiny bumps and rough patches.
There is no cure, but keratosis pilaris often responds well to moisturizers that include a combination of lactic acid, alpha hydroxyl acid, or salicylic acid. They help by softening the area as well as helping to remove the dead skin cells. Follow this treatment with a moisturizer that contains lanolin, petroleum jelly, or glycerin. You might want to try a moisturizer such as Eucerin or Cetaphil.
Since dry weather with low humidity can dry skin and make it more likely to develop keratosis pilaris, using a humidifier in your home may help.
If home treatments do not improve this condition, see your dermatologist and perhaps have a prescribed cream to help with managing keratosis pilaris.
Usually, keratosis pilaris is outgrown by young adulthood.
