Blackhead meaning in Medical Dictionary

A familiar term for just what is clinically called an open comedo. A comedo, the primary indication of zits, consists of a widened tresses hair follicle filled with skin dirt, bacteria, and oil called sebum. A blackhead has a wide orifice toward epidermis and is capped with a blackened size of skin debris. On the other hand, a closed comedo, commonly known as a whitehead, has an obstructed orifice on epidermis and can even rupture resulting in a low-grade epidermis inflammatory effect in your community.
