No one is sure of the exact cause, but hormones called androgens play a part. When you’re a teenager, androgens increase. This leads to changes in your skin that can result in clogged pores and acne. In women, hormone changes can be brought on by menstrual cycles, pregnancy, menopause, or a condition called polycystic ovary syndrome.
If one of your parents had severe cystic acne, you have a greater chance of getting it.
