Should I get the CORSX Gentle PH cleanser for the Etude Soon Jung Whip Cleanser?

I have oily, acne-prone skin and I need a good gentle cleanser. I use 100% korean skincare and so far so good, but I’d like to get a better cleanser in my routine. If anyone also has cleansing oil suggestions that’d be great. I’m 17, female, and I struggle with bad acne and oily skin. Please help😭
