Well, Comedo is a hair follicle (pore) on your skin which most of us must have felt annoying. It is of two types: Blackhead (open follicle) and White head (closed follicle). The word comedo comes from Latin to suggest the worm-like look of a blackhead that has been secreted when you press the skin around it.
