"i&#039;m 18 and i never had bad acne when i was younger. then when i was 16 started on birth control. my hormones went crazy and i started breaking out everywhere. i went to my dermatologists and she recommended aczone along with using cetaphil face wash twice a day. i started seeing results after a couple of days. it did take time to see full results. after 2 1/2 months i had beautiful clear skin, which is something i hadn&#039;t seen in a long time. i suggest you have patience with this product. i know i did and i am very pleased with the results."
