Those who solved their lifelong acne, what was the cure for you?

If you previously suffered from chronic/life-long acne and got to the bottom of it, what was the culprit for you? PCOS? Food allergies? Would love to hear how others have solved theirs!

I have struggled with acne from high school until well into my 30’s. It’s fluctuated through the years, from cystic in my teen years to mostly comodonal acne now but no matter what I do or put on it, it always persists!

Over the years I’ve been upsold every touted product by every day spa, feel like I’ve tried all the acne HG brands, hydrate like it’s going out of fashion, but (save for the few courses of accutane when I was younger), truly nothing has ever cleared it up.

For example, for the last several months have been using La Roche Posay Effaclar wash and Duo unifant (and before that, Effaclar mat) and Anthelios sunscreen of a morning (no makeup 95% of the time), and occasionally adding in azelaic acid or The Ordinary Retinol of an evening with Benzac Microbiome Moisturiser. (Have also tried double cleansing of an evening and only cleansing at night/rinsing with water in the morning). Prior to this it was CeraVe, before that just the bare basic Sukin acne prone ranges, and I’m not kidding when I say literally continues to look exactly the same no matter how high up the shelf I go.
