I got a sample of this a couple years ago and I used it while I was on an airplane to maintain my moisture. Man, this stuff really works!! I forgot about it until I got another sample of it recently, and I ordered the full size. It REALLY locks in everything and I wake up to very plump, moist, even-toned skin. It's not sticky, it's thick and emollient, but not greasy. It has a pleasant smell that isn't overpowering. It kind of smells... fresh? I'm bad at describing smells! I've used up half of my bottle and I already want to order another one. Great stuff!! My other favorite is the Missha Snail Sleeping Mask, which I had before this one. I've also tried the Laneige one, but this TonyMoly one is waaaay better. If you have oily skin, you might not like this because it's very moisturizing.
