"i began to have breakouts after the mastectomies...had to take hormonal pills.  i tried so many things, went to dermotologist and tried stuff.  what really worked was a skin regimen and taking a low does antibiotic (doxycycline)  then my daughter told me about differin.  i have been on this for almost 3 months.  there has been some good clearing up, dry patches where the blemishes were.  my face is very oily and so this didn&#039;t bother me.  i never moisturize because of the oil..all of them make my skin break out even more.  expect to have some breakouts as you get used to this.  i am almost down to the wire, things are clearing up slowly but surely.  medicare doesn&#039;t not cover lots of meds like this so otc"
