|Papules are small bumps that appear on your skin and have a rough texture. Papules typically appear on the face, but may appear on other parts of the body. Papules occur when the wall of a hair follicle break and cave in - the visible inflammation is due to white blood cells rushing in.
||Pustules are simply the medical term for pimples or zits. They are visible several days after papules have formed, when the white blood cells rise to the surface of the skin. Like cystic acne, pustules can be large and painful. Proper care should be taken to allow the pustule to heal properly.
