My dermo says it takes 5 months to see results on the pill. Personally, I can't deal with triphasic pills. I tried OTC Lo and I'm too sensitive to the hormone changes. I have also tried Yasmin (which contains an anti-androgen like Diane, which isn't available in the U.S.) and Desogen. On both I had good results.
I just started OTC and I have noticed that my pimples are the big kinds, I guess they're cysts. I used to get the small whitehead kinds, but since I started on the pill, I have been getting the initial breakout in the cystic form
