Skin breaking out immediately after starting to use new products

I just started to use Korean skincare about 3 days ago after a long history of simply using cleanser and moisturizer by brands like la roche posay for most my life. I've always had redness and acne on my chin and around my mouth but it wasn't horrible, and I just wanted to get rid of it, so I switched to korean skincare so I could have more clear and also glowing skin cuz who doesn't want that?

I ordered haruharu wonder cleansing gel, tirtir light milk toner, centella ampoule serum, and i've been using my la roche posay moisturizer as I wait for my aestura one to arrive. I have normal, sensitive skin.

Now since the very first time using these new products my acne has gotten more red, and the worst part is I'm getting acne in places I've NEVER gotten acne, so I know it's not purging. I've only ever gotten acne around my mouth, and now I have a big red spot next to my nose, and a few dots on my forehead.

I'd rather not go around testing tons of new products, so does anyone have solutions they're pretty confident will work? Or should I just go back to my old ways and try and fix the normal acne someway else?
