The sebaceous glands are oil glands in the skin. They secrete an oily substance called sebum. Sometimes the sebaceous glands become blocked by sebum and debris. When the sebum is exposed to the air and dries out, it turns black, forming a blackhead. If the blocked sebum becomes infected with staph, then it is called a pimple.





According to Wikipedia, a whitehead is similar to a blackhead, simply hasn't turned black.
