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.
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.
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.
