Keratosis pilaris causes tiny red bumps on the backs of the upper arms, buttocks, the front of the thighs and sometimes the face. According to Harvard's Women's Health Watch newsletter editor, Celeste Robb-Nicholson, as many as 40 percent of adults have keratosis pilaris. Although the condition is harmless, the bumps, caused by excess amount of keratin, are unsightly. Treatment takes months and involves softening the skin with prescription medications or home remedies and lifestyle changes.
Prescription medications
According to Mayo Clinic, four prescription medications can be used to treat keratosis pilaris. Ammonium lactate is a cream or lotion that softens the keratin plugs. Ammonium lactate also reduces skin roughness, but it doesn't lessen the redness of the skin. Urea and topical applications of corticosteroids and retinoids are other prescription medications used to treat keratosis pilaris. Urea softens skin and helps remove dead skin cells. Corticosteroids are anti-inflammatory drugs prescribed for treating the face or widespread patches of keratosis pilaris. Corticosteroids can have side effects, so are usually only prescribed short-term. Retinoids are derived from vitamin A. They help prevent hair follicles from becoming plugged and promote cell turnover. (See Reference 2)
Home remedies
According to Mayo Clinic, keratosis pilaris often persists for years, even with medical treatment. Home remedies can be used in conjunction with medications or in place of them if your condition is mild. Keeping your skin moisturized is key for treatment. Right after showering or bathing with a mild, fragrance-free soap, use a moisturizing cream or ointment on your skin. Exfoliate your skin twice a day with an over-the-counter product that contains salicylic acid, lactic acid or glycolic acid. This will help remove excess keratin and improve your skin's appearance.
Lifestyle changes
Long, hot showers are not advised for people with keratosis pilaris because they remove the skin's natural oils. Keep your water warm and only shower for about 15 minutes or less. Although it is tempting to scratch or pick at the keratosis pilaris bumps, try to avoid it. Scratching can cause an infection or make the condition worse, as can vigorous scrubbing when washing. The Hershey Medical Center of Pennsylvania State University recommends not wearing tight clothing. Also, keeping the air in your home moisturized with a humidifier can help lessen the severity of keratosis pilaris.
