What Are Comedones And Why Do I Get Them?


Well-known member
Comedo, or comedones (pl.), is the medical term for bumps on the skin that are the result of a clogged pore. The pore could be partially or fully blocked, which causes the formation of either a blackhead or a whitehead, respectively. The number of comedones on the skin along with other types of blemishes, like zits and pimples, determines if it is classified as acne. A single comedo, or a small grouping, is not categorized as acne, but is sometimes called comedonal acne.

The main cause of comedones and the problems that they cause are through the blockage of the pore. Under the skin can be found a gland called the sebaceous gland, which is there to provide the hair and skin a way of nourishment and to naturally stop the hair and skin from drying out. The sebaceous gland secretes an oily liquid called sebum, which, when secreted excessively, can cause a build up, especially when the pores of the skin are fully or partially blocked by dead skin cells, or other substances. The result is a small pocket of built up oil that causes a bump on the skin, a comedo.
