"i used the samples my doctor gave me for oily skin.  it smelled terrible, but it really worked for my oily skin!  i got the prescription and, guess what...  it smells great and doesn&#039;t work!  i brought it to my doctor and she compared the  labels and they matched up.  i thought maybe it was a fluke, so i got the medicine again and same thing...  good smell, but doesn&#039;t work at all.  it was so depressing because i had finally found something that controlled my oil, but i can&#039;t ask for a lifetime of samples!  at $50 a pop (with insurance), i&#039;m not going to keep trying it."
