I was on it a year. U need that long.
QUOTE=Millie228;39955392]Yeah, the thing is, even a shorter course will get rid of it, but you need a longer one for the effect to be permanent.
I had really bad acne when I was 13-14, up to around 16. I know for a fact that it is genetic, my mother had it up till her 20s, my sister as well (in fact she had until she went at Roaccutane at 25). Of course a poor diet/hygiene etc makes it worse, but for most people who really struggle with acne, a lifestyle change doesn't matter (I use premium skincare and am very healthy). I'm sure you already know this, but some people don't.
I did Roaccutane for about 2 months and it really worked. However it started to come back and another dermatologist told me I should have used it for a longer time. So make sure the Doctor knows that you know that you need a longer dose.
