"i&#039;m just gonna get right to the point by saying that i&#039;m just about to hit my 12 week mark on epiduo and it has completely cleared up my acne!! from 1-4 weeks my acne kept getting worse. from 4-6 weeks it was just kinda stuck in one place where it didn&#039;t really get worse but never got better. from 6-9 weeks it slowly started to get better but i was still waking up everyday with a new pimple. then from 9-12 weeks i really started noticing a difference. pimples stopped occurring everyday, (with the exception of a couple because my period was starting). so for everyone using this product, just give it time to work! and for anyone wondering, i use cetaphil derma-control foam wash in the morning and night but only apply epiduo at night (waiting 30 min after to apply the moisturizer) also i really recommend getting the epi-tracker app to track your progress. so good luck everyone"
