What Causes Acne?

There are several contributing factors to acne:There are several contributing factors to acne:
  • hormones,
  • bacteria,
  • increased sebum production, and
  • changes within the hair follicle.

During puberty or adolescence there is an increase in the production of sex hormones (mainly androgens and testosterone). This causes the sebaceous glands to produce increased amounts of sebum. Also during puberty, the skin cells lining the hair follicle shed at a faster rate, increasing the probability that the sebum and skin cells present will stick together and result in blockage of the hair follicle.
The number of bacteria on the skin surface also increases during puberty.
Young men are more likely to have severe, longer lasting acne than women due to higher levels of testosterone.
Young women are prone to cycles of acne due to hormonal changes that occur during their menstrual cycle.

Other factors that may contribute to acne include:
  • use of greasy or oily cosmetics
  • a family history of acne
  • use of certain medicines such as glucocorticoids, iodides, lithium, bromides or anticonvulsants;
  • abrasion caused by over-vigorous scrubbing; frequent shaving or other manipulation to the skin;
  • exposure to airborne pollutants;
  • exposure to high heat and humidity.
