On some pimples it works like a dream but on some other it doesn't have any other effect than irritate them more. The next morning I can see the marks of the patch. I have to hydrate my skin thoroughly otherwise the dry patches left by the patch looks horrible with makeup on 

loved these. kind of gross how they suck the pus out of pimples, but very effective. make sure to use after acne turns white and not just when its a painful red spot or else the patch can't pull the pus out

I love these acne patches! They help heal my pimples super fast! 

will always rave about this product it's just that good! 

I just can't get enough of these patches and always stock up whenever I buy from StyleKorean. These are one of my few holy grail skincare products because they work so well, I'm not even exaggerating. They work best on clean skin where the pimple is very ripe and/or has been opened already. Not only does it suck out the white sebum inside, it also sort of heals the pimple so that the skin no longer has a bump.
