[Routine Help] Stubborn Acne

I’ve been struggling with acne for years. I’ve been using tret for over two years, pretty consistently (2-3 times a week), except for a couple of times when I stopped for a month. My skin gets super dry by the end of the night but wakes up oily, then dries out again during the day until I work out. I use a face razor to clean up my mustache area, but it always makes me break out. I’ve avoided waxing or laser because I feel like they’d be too harsh for that spot because of tret. I’m Latina and grow my hair fast and don’t know how else to get rid of it. I’ve thought of dermaplaning professionally but I feel like my acne is too bad to do it. My skin looks a big brighter and clearer because I just recently shaved with a face razor (I know they’re bad I just don’t know what else to use). I’ve been off hormonal birth control for over a year after using it for five years, and while my acne has gotten a bit better, I still get the same monthly flare-ups. My routine is super basic because I always thought less was more, but now I feel like it’s not working, and maybe I need to change things up I just don’t know how to do it completely. Should I all together stop tret and build an entire new routine?
