Comedo is the primary sign of acne. Comedo occurs when a plug of oil and dead skin cells becomes trapped within the hair follicle. There are many different types of comedones. The comedo may be closed or open; the closed comedones are the whiteheads and the closed comedones are the blackheads. 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.

Blackheads are typically caused by excessive oil and makeup, which can facilitate the multiplication of the bacterium Propionibacterium acnes, the predominant anaerobe of the normal skin flora. Bacteria, which live in everyone's skin but generally mind their own business, feast on this oil, multiply, and cause the surrounding tissues to become inflamed. Common over-the-counter medications for comedo are Benzoyl peroxide and/or salicylic acid. Both medications can be found in many creams and gels used to treat comedo through topical application. Both medications help skin slough off more easily.
