My complexion instantly brightens! I used the one that came with the gift, and then purchased a full set of four on Qoo10. To use it, I like it cold, so I prepared ice water and poured 6-7 tablespoons into it using the included spoon. This cools my skin and feels great during this hot weather, so I highly recommend it! When peeling it off, some areas peel off easily, but some residue remains around the hairline on my forehead, so in those cases I gently remove it with a damp tissue. I don't think rubbing it is a good idea. After that, I did some skincare and went to sleep, and the next day my skin looked better and the dullness was gone, so I'd like to incorporate it into my special skincare routine.
