I got this acne patches to see what the hype was all about after seeing countless youtubers, bloggers, redditors and this is the best must-have Korean skincare products I've tried so far. I apply the patches onto the pimple before going to bed and the pimple is gone when I wake up. This is my go-to fast acting acne treatment Tip: I use it on top of Cosrx Ac collection spot cream to make it even more effective!
