What exactly is Acne?

What causes acne? Acne occurs when the hair follicle pores
become blocked. The oil called sebum builds up inside the pore and becomes
infected with bacteria. When the infection remains under the skin surface, it
develops into a whitehead. When the infection partly reaches the surface and
changes color, it develops into a blackhead.
