I read this and it makes sense too, if your acne has not gotten better with the treatment you are using in 12 weeks, you need to try something else. Unless you are on BCP that can only start working in 12 weeks but topical should not take 6 months. You can try a BCP I am on my fith month and got some improvment finally but my acne was REALLY BAD clogging up the ying yang. I had litterally 120 clogged pores on my face, now I can count them. I have about 25 now and last month I had 55 so each month I am getting better. Something to look into. I am on yamin but I broke out from it the first three months. The past two months is when I am noticing some imrovment. If you have patience a BCP can help. Also you can stop trying the darn retin a and try aby skincare at http://www.abyskincare.com
. Five people who had problems with retin a tried this program and got clear in about three weeks. Its like proactive but much much stronger cause they have powerful strenths of stuff and a doctor or nurse there can also make suggestions.
