II. Blackhead Causes:
At puberty, the oil glands of the skin start producing an oily material called sebum. Sebum lubricates the skin. Sometimes the wall of the oil gland breaks and spills the sebum within the skin which causes redness, swelling, and pus (in other words, a pimple). Plugged oil glands may form blackheads and whiteheads. Blackheads are not caused by dirt.
There is a bacteria that normally lives on the skin called Propionibacterium acnes. This bacteria lives on the sebum produced by the skin oil glands. Sometimes, this bacteria multiplies and causes inflammation and acne.
