When the follicles are wide open than its normal size, there are more chances for dead skin cells and sebum to accumulate. When this happens, open comodones or better known as blackheads are formed. They are black in color because the dead skin cells and the sebum that have accumulated have gone through the process of melanin oxidations.
Blackheads are more common to people with oily skin and combination skin. There are many ways to treat blackheads. The best blackhead treatment is one that deals with the source of the problem.
