Use them: If you break out without fail around the time of your period.
How they work: Acne in adult women is often due to fluctuating hormones. Birth control pills contain ingredients that, while controlling your menstrual cycle, alter your body’s androgen, a sex hormone that can increase oil production and cause blemishes. Three brands—Ortho Tri-Cyclen, Estrostep/Fe, and Yaz—have been approved by the Food and Drug Administration (FDA) to treat acne.
Good to know: Drugs aren’t the only way to keep hormone-related breakouts in line. In general, getting adequate sleep, lowering stress levels, and eating a diet rich in antioxidants can help, too, says Treloar.
