Acne Blackheads

Acne Blackheads result when a pore is only partially blocked, allowing some of the trapped sebum, bacteria, and dead skin cells to slowly drain to the surface. The dark color associated with its appearance is not caused by dirt. Rather, it is a reaction of the skin's own pigment, melanin, reacting with the oxygen in the air. As a whitehead has a short life cycle, a blackhead is a firmer structure, and can often take a long time to clear.
