Keratosis pilaris is a harmless skin disorder that causes small, acne-like bumps. Although it isn't serious, keratosis pilaris can be frustrating because it's difficult to treat.

Keratosis pilaris results from a buildup of protein called keratin in the openings of hair follicles in the skin. This produces small, rough patches, usually on the arms and thighs. Though quite common with young children, keratosis pilaris can occur at any age.

Many people are bothered by the goose flesh appearance of keratosis pilaris, but it doesn't have long-term health implications and occurs in otherwise healthy people.

Keratosis pilaris usually resolves without treatment. But if you're concerned about the appearance of your skin, your doctor can help you determine the best course of treatment, which includes self-care measures and medicated creams.
