There are several factors that can cause acne such as hormonal changes in adolescence or pregnancy, birth control pills, bacteria in the skin pores and use of anabolic steroids among other things.

One important factor behind acne experts believe is an increase in the male sex hormones androgens which increase in both boys and girls during adolescence that cause the sebaceous glands to enlarge, creating more sebum (oily secretion).

Experts also believe acne to be in part, hereditary.
