Causes Of Acne
Acne is caused when tiny holes in the skin, known as hair follicles, become blocked.
Teenage acne is thought to be triggered by increased levels of a hormone called testosterone, which occurs during puberty.
The sebaceous glands are particularly sensitive to hormones.
It is thought that increased levels of testosterone cause the glands to produce much more sebum than the skin needs.
Acne in families
Acne can run in families. If your parents had acne, it’s likely that you will also develop it.
Acne in women
More than 80% of cases of adult acne occur in women. It is thought that many cases of adult acne are caused by the changes in hormone levels that many women have at certain times.
These times include:
Periods: Some women have a flare-up of acne just before their period
Pregnancy: Many women have symptoms of acne in pregnancy, usually during the first three months of their pregnancy
Polycystic ovary syndrome (PCOS): A common condition that can cause acne, weight gain and the formation of small cysts inside the ovary
