"i am in my 30&#039;s and have hormonal acne.  i have issues with my thyroid and produce too much androgen.   thank goodness for this stuff!!!  it took a month or so to work but i&#039;m so thankful not to have cystic chin acne.  i have suffered on and off since my teens.   usually always have a few cystic bulbs on my chin, cheeks, or neck.  i was supposed to use this rx along with oral antibiotics but they made me too sick so i didn&#039;t use them.  this topical rx did the job for me.   i&#039;ve tried so many things."
