This is an amazing overnight mask. I loved the lightweight gel like consistency! I have dry skin and very sensitive skin, whenever I get red patches I just slap this cream on and I wake up with plump, hydrated skin, any previous redness is completely gone. I'm not too sure of the whitening effects, but my face does look brighter. I've loved all of COSRX's products so far and this is is probably now my favourite item from their range!
