Korean skincare for hormonal acne - what actually works?

I struggle with hormonal acne that flares up around my period. I have tried many Western products but they are either too harsh or not effective. I want to try a Korean skincare approach since I have heard it is gentler but still effective. What Korean products or ingredients are best for hormonal acne? I have heard about things like centella asiatica, mugwort, and propolis. Are there specific Korean brands that target acne-prone skin? I also want to avoid products that might cause more breakouts - which ingredients should I avoid?
