It's so moisturizing that when I apply it in the evening, my skin still feels firm and great the next morning. I'm on my third bottle now, and I love it so much that I've given it as gifts to my family members. They're all very satisfied with it!
The price is quite steep, making it a bit burdensome to use the entire Sulwhasoo line as a full set. However, despite the cost, the level of satisfaction remains high.
