If you know korean skin care, son you know you have to do double cleansing every night. The first one is for remove your make up and the second step is a deep cleasing to remove the make up residues. There is always residues, but this foam wash it very well. I have a very troublematic skin, but I veen washing my face every morning and night with this and now a have a lot less pimpless and my skin look brighter (of course I use other products too, but this is a game changer).
