acne
"it pretty much ruined my skin. . ive been using epiduo for 5 months now and it worked amazing and my dermatologist told me if I used aczone in the morning my red marks would go away faster.  What it did was create more red marks and made it insanely dry and red and horrible. I was on aczone for 2 months before I gave up like last week and now it burns whenever I wash my face so I have to wait a while for this stuff to drain out of my system yeah don't recommend but maybe it's because i use epiduo"
