Keratosis Pilaris

WHAT IS KERATOSIS PILARIS

Keratosis pilaris (KP) is a genetic disorder of keratinization of hair follicles of the skin. It is an extremely common benign condition that manifests as small, rough folliculocentric keratotic papules, often described as chicken bumps, chicken skin, or goose bumps, in characteristic areas of the body, particularly the outer-upper arms and thighs. Although no clear etiology has been defined, KP is often described in association with other dry skin conditions such as ichthyosis vulgaris, xerosis, and, less commonly, with atopic dermatitis, including conditions of asthma and allergies. They are usually white but sometimes rather red. They usually don't itch or hurt.

WHEN DOES IT OCCUR?

Keratosis pilaris is particularly common in teenagers on the upper arms. KP affects nearly 50-80% of all adolescents and approximately 40% of adults It may occur in babies where it tends to be most obvious on the cheeks. It may remain for years but generally gradually disappears usually before age 30. Keratosis pilaris is unsightly but completely harmless. It is usually worse during the winter months or other times of low humidity when skin dries out, and may worsen during pregnancy or after childbirth.

WHAT IS THE CAUSE?

The etiology of keratosis pilaris (KP) is not fully known. The definite association of hyperkeratinization has been established. Of persons affected, 50-70% have a genetic predisposition. Dry skin conditions seem to exacerbate the disease. Symptoms generally tend to worsen in winter and improve in summer. Common associations include a family history of KP, ichthyosis, or atopic dermatitis. KP is more common in siblings and in twins.

WHAT IS THE TREATMENT?

Treatment of keratosis pilaris is not necessary, and unfortunately often has disappointing results. With persistence, most people can get very satisfactory improvement. Initial treatment should be intensive moisturizing. Try a cream such as Acid mantle or Aquaphor™ after bathing, and re-apply the cream again several times daily.

If this does not help, change to a medicated cream containing urea (Carmol, Vanomide, U-Kera, Ultra Mide, Nutraplus) or alpha-hydroxy acids (Gly-sal or Glytone KP Kit) applied twice daily - it may be too irritating to use more often. More aggressive home treatment can be done if ones skin can tolerate it. The plugged pores can be removed by taking long, hot soaking tub baths and then rubbing the areas with a coarse washcloth, stiff brush, or 'Buf-Puf'.

Prescription medicines that may help include antibiotics (Erythromycin, Bactrim) or topical corticosteroids if the spots are very red. Blu-U light can also be used for difficult cases.
