Acne usually develops during the age adolescence which is typically
16 to 18 years old. The main reason is the surge of sex hormones which
stimulates the production of more oil at the oil glands. Acne usually
subsides after the age of 25 years old but about 15% of women and 5%
of men still continue to have acne above this age.
1.
Genetics
If your parents have acne during their teenage years, then you have
a higher chance of getting acne. You may also inherit an overactive
oil gland from your parents or grandparents.
2.
Hormones
High amounts of hormones stimulate the oil glands to produce more oil
and sebum. High amounts of sebum lead to pore clogging. High levels
of sex hormones are expected during puberty. During menstrual cycles
hormonal activity is also high.
3. Anabolic Steroids
They are used by body builders to increase muscle mass. The
use of anabolic steroids increases the hormone testosterone which is
also converted to dihydrotestosterone. Dihydrotestosterone causes the
oil glands to pump more oil.
4.
Medication containing halogens (iodides, bromides,chlorides), lithium,barbiturates
or androgens
5.
Exposure to high levels halogenated aromatic compounds (chlorinated
dioxins and dibenzofurans)
A good example of a victim of this type of ACNE also known
as Chloracne is the Ukrainian president Viktor Yushchenko.
