Keratosis pilaris (KP, also follicular keratosis or chicken skin) is a common, autosomal dominant, genetic follicular condition that is manifested by the appearance of rough, slightly red, bumps on the skin. It most often appears on the back and outer sides of the arm (though the forearm can also be affected), and can also occur on the thighs, hands, and tops of legs, sides, buttocks, or any body part except glabrous skin (like the palms or soles of feet). Often the lesions will appear on the face, which may be mistaken for acne.
