I never really had bad acne until grade 12, which would be last year, I started getting small ones on my forehead, but really bad cystic like ones on my cheeks as well. My doctor gave me Tactuo. I've been on Tactuo for awhile now, more than 6 months I would say, and my skin really cleared up in the first few months. Now this month, I feel that it's coming back. That may just be because of my period? I'm not sure if that may have something to do with it. I just hope my skin hasn't become immune to Tactuo. I don't want to go back to having acne all over my cheeks and stuff. It's embarrassing

Does Tactuo/Epiduo eventually wear off?
