Keratosis Pilaris (skin rash)

    Keratosis pilaris is a very common benign skin disorder which can affect up to 50% of all teenagers and adults, and it usually begins in earlier childhood.  It is a disorder of keratinization of hair follicles where the openings of the hair follicles get plugged up with a protein called keratin.  The characteristic papules (prickly bumps) are usually found on the extensor (outside) surfaces of the upper arms, anterior thighs, and cheeks.  They eventually go away later in adulthood, but they tend to persist for many years.  There is a greater likelihood that a child will develop this chronic rash if one or both parents have it.  This rash tends to be worse during the winter when the air is dryer.

    Treatment for keratosis pilaris is only marginally effective and it only provides temporary relief.  There are “keratolytic” prescription creams such as LacHydrin, LactiCare, and Ultalytic Cream which help hydrate the skin and remove keratin scales.
They may be applied two to three times a day.  A moisturizing cream may help alleviate rough scales, and one may also attempt gentle exfoliation with a pumice stone, washcloth, “loofah” sponge, or “Buff Puff.”  It is also recommended to use a mild soap (such as Dove) to help prevent excessive dryness.
