Similar efficacy as compared to the normal Cosrx patches. The patch was rather unnoticeable but definitely not exactly invisible, especially if you have makeup on (the rims would show). Also, as the day goes by or if your face is particular oily it would become more obvious. Would definitely repurchase again.
perfect cover for my pimples
Works most of the time
I have acne from time to time after eating some chips and before my monthly period so I always use this for those days. I like this one better not the red one from Cosrx because this is thinner and more effective. I lost count of how many packs I have purchased :)
It can really suck up the pus!
