Ordered those to test them out and compare them with the COSRX ones.

When it comes to performance, tje cosrx ones do work really well and I have been using them for quite a long time. This SOME BY MI patches are a bit different - they are thicker in the center and rhe rest of the patch is thinnier. To my opinion - this sits on the face much better. The pimple was eliminated in just one night when I applied it.

Subjectively, I would say I like these slightly more than the COSRX ones.

Considering however I can get those COSRX much cheaper and I have stocked on them recently, I will use them and I plan to ocasionally buy those from SOME BY MI when they are subject of promotion.
