Yes! Since acne is primarily a result of hormonal fluctuations, even adults can experience acne. Some of the hormonal fluctuations are caused due to changes in the body during pregnancy, menstrual cycles, or menopause, while others occur as a side effect from birth control pills, testosterone supplements, steroids, seizure medication and other hormone-containing medications. In some adults, acne can also be caused as a result of their genetic makeup which makes them prone to clogged pores.
