Birth control pills
Birth control pills contain 2 synthetic hormones; estrogen and progestin. This extra intake of hormones not only inhibits fertilization, but also controls the menstrual cycle. While using these medicines you will have less menstrual cramps because of lighter periods. These pills cause the sebaceous glands to produce less sebum. Estrogen and progestin slow down the production of sex hormones, which prevents it from signaling the oil glands to produce more oil.
