Yes. Acne does not only discriminate based on age. The reason that many teenagers get acne is because their condition is triggered by rising hormones of puberty. You may be experiencing adult acne from hormonal fluctuations due to pregnancy, menstrual cycles, or menopause. You can also develop acne as a side effect from certain hormone-containing medications like birth control and testosterone supplements or other medications like steroids or seizure medication. Some adult men and women will continue to produce acne simply because their genetics cause their pores to clog too easily.
