Your journey sounds a lot like mine. Then I discovered the regimen and I got completely clear and stayed that way. I very highly recommend.
Oh yeah, also, it's so hard to know what's causing what. There are SO many variables in life and we can think, for instance, that it's our skin barrier that's the issue, and then, whadayaknow, it was something else. Long story short, it doesn't matter all that much in the short term. Get on the regimen and get completely cleared up. Then, you can try to get to the root of things, like getting on a low inflammation diet, taking some supps, destressing, leaving your skin untouched, etc. It may be a combo of factors. Make sure to take the quiz on here too so you can think about that other stuff for long term.
