What Causes Acne To Occur?

[myron fehr]

Unfortunately the exact cause of acne is unknown, but many doctors
believe it results from several related factors. One of the most
important factors is a person's changing hormone levels. Often these
hormones, known as androgens (male sex hormones), will increase in
both boys and girls during the pubescent stage of their lives. This
can cause the sebaceous glands to enlarge and produce more sebum.
Another cause of acne is heredity or genetics as researchers believe
that there is a tendency to develop acne your parents suffered from
it. In fact studies have shown that many school-age boys who are
suffering from acne have a family history of the disorder.
Acne is caused by the sebaceous glands becoming over active. They then
secrete oily substances on to the skin . People who are prone to acne
are especially sensitive to blood levels of the hormone called
testosterone and this triggers the sebaceous glands to then produce an
excess of sebum (oily substance). But at the same time the dead skin
cells lining the openings to the hair follicles are not shed properly
and they begin to clog up these follicles. The effect of the excess
oil and the blocked follicles results in blackheads and whiteheads
forming.
The build up of oil in the hair follicles creates the ideal
environment for a bacterium called Propionibacterium Acnes to grow.
This normally lives harmlessly on your skin but when the environment
is right for them they will grow. The bacteria feeds off the sebum and
produces substances that cause your body's immune system to respond.
This in turn inflames the skin and creates the redness that we
associate with spots. In the more severe inflammatory acne cases cysts
will develop beneath the skin's surface and these can then rupture and
spread the infection into nearby skin tissue. This can often result in
scarring to a person's skin.
The good news is that some people, once they are out of puberty, will
no longer suffer from acne. Hopefully the information above has
provided you with some explanation as to the cause of
acne.
