What it is
1. This rich, intensive moisturizing care mask contains a concentrated serum of retinol derivatives and fresh collagen, leading to firm, elastic, and supple skin with less visible pores. 2. Each sheet contains the equivalent of a bottle of rich, viscous serum. The extra-thick sheet holds the serum in place and delivers it to your skin. 3. Designed for exceptional adhesion, it fits snugly to your face, providing thorough care for troublesome areas like the corners of your eyes, nose, and mouth.
Ingredients
How to use
To ensure the serum is absorbed into the mask, gently knead the entire packet with both hands before each use. 1. Remove one mask at a time and place it on your face, ensuring it adheres securely. 2. Leave on for approximately 3 minutes for daily use, or 5-10 minutes for special use. 3. Remove the mask and massage the remaining serum into your skin.

We're working on rolling out prepaid duties for more countries soon.
