Really good... i love it so much... 

I had a huge pimple for a few times before my period week. Thanks to COSRX, they never ever disappoint me. 

I used a pimple patch where my pimple was and the next morning, all the white sebum of my pimple has been removed and the pimple was smaller and unnoticeable.  

Thank you COSRX for being my lifesaver! 

this product is just DAEEBAAK!!
 

These patches work best on those big sore pimples that haven't fully formed yet, you squeeze out a little of that clear puss and put a patch on and overnight the pimple is gone!
