Adapalene / benzoyl peroxide
"I never had cysts, just mild breakouts and comedonal acne on my forehead and BARELY on my cheeks or on my chin. I can't believe how much I took my skin for granted. I asked my pediatrician for a medication to help my skin before freshman year. Wow. My doctor gave me epiduo and by 8 weeks I knew epiduo wasn't working for me. I had cystic acne on my cheeks, which I've literally never had before in my life. it wasn't something I've ever been used to. My right cheek, which used to be the worst, it literally completely cleared after this 12 weeks, BUT I paid the price. my purge period was 5 times worse than everyone else's, and much longer. I had about 7-9 cysts on my freaking cheek at a time. Try it out. I have much clearer skin but I paid for it"
