Keratosis pilaris occurs most commonly during childhood and produces small, rough spots (papules) that are typically skin-colored. They usually appear over the outer surface of the upper arms and thighs, but may also occur elsewhere on the body. Dry skin (especially during winter months) makes the condition worse. Keratosis pilaris tends to be inherited and may be associated with atopic dermatitis.
