What does keratosis pilaris look like?

The groups of small horny bumps are most common on the backs of the upper arms and on the fronts of the thighs. Sometimes keratosis pilaris also affects the torso, back, buttocks and, in less common forms, the face and eyebrows as well. Some redness may appear around the small spiky bumps. If a plug is pulled off, a fine coiled-up hair may be found inside it.
