The exact cause of acne in most cases is not known. Many doctors believe that acne results from several different factors. One of such factors, and that is very important, is the rise in one's hormone levels. During the pubescent years, the male sex hormones called androgens increase in boys and girls. This can cause the sebaceous glands to enlarge and produce more sebum, which results in acne.

It is believed that the tension on either one develops acne or not is hereditary. Many studies have shown that boys who have acne also have a family history of acne. Acne is caused by when the sebaceous glands begin secreting oily substances onto the skin. Those with acne are especially sensitive to testosterone, and it triggers the glands to produce too much sebum, which is an oily substance.

While the oil increases, the dead skin cells that line the hair follicle openings are not shed, which in turn clogs the follicles. With the combination of excess oil and clogged follicles, blackheads and whiteheads form. For many people though, they experience acne only during puberty.

For others, the build up of oil in the hair follicles will create the ideal environment for Propionibacterium Acnes (a bacteria) to grow. This bacteria actually naturally grows on your skin and lives harmlessly, but in the "right" environment it will grow.

Propionibacterium Acnes feeds off the sebum, and then produces a substance causes the body's immune system to react. This then inflames the skin and creates redness and spots.

With worse inflammatory acne, cysts will develop under the skin's surface. These will then rupture and spread infection into adjacent skin tissue. This can often result in one's skin scarring.
