I always get a acne problem when I'm on, big juicy hurting mofo's, I got my girl popping the ones I cant reach at least 2 times wk (good girl huh) areas are back, shoulders, and chest. I usually have a few good ones hear and there during cycle but as soon as I'm near the end look out and it stays bad 4 aprox 4 wks after my cycle. I use 2000mg B5 a day (500mg 4 per day) spread them out as best you can, a very firm lufa sponge or whatever u call it with that Nizoral 1% (2% is better but you need a script) shampoo to scrub acne areas twice a day, and wash face with a good oil free acne wash (Neutrogena) than use an astringent (sea breeze) on acne areas as well, between all this crap it does help but not totally acne free.. accutane would be the only thing from what I hear, if you got insurance and a doc 2 get a script go 4 it, it can be kind of pricey without.... hope this helps..
