I have just finished week 20 and can say for the first time as of today I do not have one single active spot on my entire body!! For those like me who were doubtful and all those who are reading that people clear straight away, if you look at it like this: it has taken me 5 months to get to this point. I can still feel one or two clogged pores on my cheeks but the rest of me feels very smooth. Being on 30mg once a day and having 6 more months to go to meet the total required dose, I look at it as I am not even half way there yet and if I get double the improvement I have so far then in the end I think I will cry with joy to the derm! As I said before I still have red marks but they have improved slightly and I trust my derm when he says they will go. Its better than active acne by miles anyway!
