Persistent acne found me years ago and stuck around enough to impact my confidence, while I tried almost everything marketed to fix it… most of which didn’t. I don't really break out anymore, but I still can't point to the one thing that changed it. What I can point to is a handful of things that shifted around the same stretch of time: how I ate, how seriously I took hydration, how I actually dealt with stress instead of pushing through, gentler products across skincare, hair, and laundry, and one specific medical step I took under professional guidance.
None of these alone explains it, and I'm still not sure any single one is the actual reason. Together, it's the closest thing I've got to an answer.
