KERATOSIS PILARIS HANDOUT

Keratosis pilaris (KP) is a very common condition in young people in which the hair follicle becomes clogged and variably inflamed. Rough skin like sandpaper affecting the outside of the upper arms is most common, but KP may affect the cheeks, thighs, and/or back as well. KP is not contagious.

Treatment

KP is entirely benign and need not be treated. Most young people grow out of it, but this can take years, even decades. No cure has been found, but the following OTC treatments may help. They are broken up into 3 main categories which can be used alone or in combination (see pictures below for examples.)

Caution. Some of these products may be too irritating for the face. For KP of the face, start with Differin gel and a moisturizer.

1. Retinoids like Differin attempt to unclog the pores and "normalize" the skin. Differin is available over-the-counter and is applied once a day.
2. Moisturizers: Dry skin can make KP worse so moisturizers help. They may be applied once to many times per day--separate or after any other therapy.
   
3. Exfoliant/Keratolytic: Ingredients like ammonium lactate, urea, and salicylic acid all try to reduce the roughness of the skin. Exfoliants are usually applied once or twice a day. They usually already come with a moisturizer, so if you use one of these products, you may not need a separate moisturizer.

One common approach is to combine Differin with an exfoliant/keratolytic--one in the morning and one at night. If these products fail and your case is particularly bothersome, see a dermatologist.
