First of all the so-called birth control pills for acne should refer to the application of progestogens like cyproterone to treat acne. First of all, for acne, acne can be caused by a variety of clinical conditions. For example, some patients with polycystic ovary syndrome (PCOS), in addition to the obvious facial acne, such patients also have obvious symptoms such as obesity, body hair, and obviously high androgen, and such patients are often accompanied by menstrual scanty symptoms. For such patients, the treatment can be applied to such drugs as cyproterone, which does have a contraceptive effect. However, not all patients with acne need to take a contraceptive such as cyproterone. The majority of acne sufferers can find relief through lifestyle modification and topical application of retinoic acid ointment and benzoyl peroxide gel.
