I was honestly skeptical but after two weeks my skin looks like glass. The mask is so cooling and you can literally see the gel turn clear when it's done absorbing. Obsessed.

I subscribed for the bundle of 2 and the free shipping + VIP group is a lovely touch. The K-beauty ebook actually taught me how to layer properly.

I cancelled my serum, my night cream, and my under-eye gel. This mask twice a week is doing more than all three combined. My fiancé even noticed.

Unboxing felt like a luxury moment. Box is heavy, the sachets are individually wrapped, and the instructions are beautiful. Skin feels plump after one use.
