Signs & Symptoms
- Papules (small, raised bumps) with the following characteristics:
- Papules are small, firm and white, with a dry “sandpaper” feeling.
- Papules are clustered. Each one is about 1 mm in size.
- Papules are at the openings of hair follicles. They can be scooped out with the fingernails.
- When scooped out, a papule usually contains a coiled hair inside of white, semisolid material.
- Papules don’t itch or hurt.
- History of skin allergies.
- Family history of keratosis pilaris.
Diagnosis & Treatment
Diagnosis is made by history and examination.
- Take long soaking tub baths.
- Use mild, unscented soap.
- Scrub gently with a stiff brush to remove the plugs in the follicles temporarily.
- Apply lubricating ointments or creams to the affected areas 6 or 7 times a day. The most useful time is immediately after bathing when lubrication helps the skin retain moisture.
Medicine usually is not necessary for this disorder.
No special diet.
Secondary infection of papules.
Keratosis pilaris is a chronic, harmless skin problem with no permanent cure. Individual papules may come and go over a matter of weeks. All gradually disappear by age 30.
