I will admit that I had my doubts when I started to read about sleeping masks - I could not imagine getting a mask all over my sheets/hair/pillowcases until I tried a sample of Korres Greek Yogurt overnight mask and all doubts that I had vanished and now I want to try every single overnight mask that there is! I used this one for the first time last night and loved it. My skin is absolutely flawless today. You apply it after using your regular serum/moisturizer about 10 minutes before going to bed. It absorbed really quickly into my skin and washed off easily in the morning.
I don't think that they are made to use every night, but, seeing is believing and my tired stressed out skin looks amazing today.
5 Stars - highly, highly recommend!
