I started using this product after receiving a trial size from my mother. I find sheet masks a hassle, so I like the wash-off type because I can use it during bath time, but I thought the downside was that it doesn't have much of a lasting effect. Rather than being moisturizing, I like the feeling that it leaves my skin feeling firm and smooth thanks to the clay effect. I thought the moisturizing effect was only moderate, but my husband, who doesn't do much skincare, really liked it, and was so happy that he could use it for several days without feeling too dry, so he decided to buy the full product. As someone who is used to using cosmetics, I didn't notice much, but I thought it had a solid effect.
