It moisturizes perfectly! It's not sticky, has no smell, doesn't interfere with other cosmetics, and doesn't irritate! This was my first time using a dropper that you can pull up, so I was a little confused, but it seems like it will be easy to use up. The packaging is quite luxurious and I had high expectations, but I didn't feel much effect other than moisturizing. There are better serums for this price, so I won't be buying it again. If you're going to Korea, you might be able to get it cheaper at the duty-free section of a department store.
