"so i&#039;ve had a roller coaster experience with this bc...
1. tri-sprintec: summer 2013 - 2014 (21/22 years old) - cleared my skin flawlessly within a month, stayed clear for a whole year
2. tri-previfem: summer 2014 to spring 2015 - took three months to only partially clear my skin, had to switch prescriptions because of a new gyno
3. tri-linyah: spring 2015 - took two month to nearly completely clear my skin
4. tri-sprintec (again): present - it has been 4 months and i have never had worse acne in my life. i have terrible cystic acne all over my cheeks and some on my jawline. my forehead, nose, and chin remain clear so i know its all hormonal acne. i will be switching back to tri-linyah in the hopes that i can get my clear skin back :("
