Comedones may be closed or open. A closed comedo has an obstructed opening to the skin and may rupture to cause a low-grade skin inflammatory reaction in the area. The common name for a closed comedo is a whitehead. An open comedo has a wide opening to the skin and is capped with a blackened mass of skin debris. It is commonly known as a blackhead. Acne occurs when sebaceous glands of the skin begin to secrete oil during puberty.
