How it works
Betula Platyphylla Japonica Juice leads the ingredient panel on this mask. Betula Platyphylla Japonica Juice is Asian white birch sap, tapped in spring. It is over 98 percent water with trace minerals and sugars, and Korean formulas use it in place of plain water as a hydrating base. On this panel it sits alongside Allantoin, Laminaria Japonica Extract and Ulmus Davidiana Root Extract. Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin.

Key actives
Betula Platyphylla Japonica Juice
Betula Platyphylla Japonica Juice is Asian white birch sap, tapped in spring. It is over 98 percent water with trace minerals and sugars, and Korean formulas use it in place of plain water as a hydrating base.
Allantoin
Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin.
Laminaria Japonica Extract
Laminaria Japonica is kombu kelp. Its extract carries alginates, minerals and iodine, and it is used as a hydrating, mineral-rich ingredient.
Ulmus Davidiana Root Extract
Ulmus Davidiana is Japanese elm, whose inner bark yields a naturally slippery mucilage. Korean formulas use the root extract for that cushioned feel and for the look of reactive skin.
Round Lab Birch Moisturizing Double Gel Mask 10ct
Is the Birch Moisturizing Double Gel Mask 10ct on this page the Korean-market formula?
Yes. It is the release Round Lab makes for sale inside Korea. The same product name can carry a different ingredient list or a different size in an export version, and we list only the Korean one. Round Lab is one of the brands where we have documented a Korean formula and a US formula that genuinely differ.
Where does the Birch Moisturizing Double Gel Mask 10ct sit in a routine?
It occupies the mask step. Build the routine around the step you are replacing rather than the brand you recognise: a cleanser, a hydrating toner, one serum and one moisturizer is a complete routine, and four products chosen carefully tell you more about your skin than ten bought at once.
What size is the Birch Moisturizing Double Gel Mask 10ct?
10 ea. That is the size Round Lab sells in Korea for this product; it is the same size sold in Korea: we do not substitute an export format or a US size for the Korean one.
How do I check that this Round Lab unit is genuine?
Round Lab publishes no verification route of its own, so ignore any third party site that claims to run one for it. Match the batch code on the box against the code printed on the bottle or tube itself; the two are stamped separately and should agree. Your unit ships with its Korean-market barcode and its batch code intact, because the production date stays yours to read.
How does buying the Birch Moisturizing Double Gel Mask 10ct here compare with a US retailer?
The unit sold here is the unit built for the Korean market, with the Korean barcode and batch code intact on the box. A US listing carrying the same product name may be the export version and rarely tells you which one it is sending.

How to use
- Use the Birch Moisturizing Double Gel Mask after toner, in place of your serum step, in the evening.
- Unfold the sheet, line it up at the eyes first, then smooth it outward so no air is trapped underneath.
- Take it off at the time printed on the pack, pat in the essence left behind rather than rinsing, then go straight to your moisturizer.
- Two or three evenings a week is a normal rhythm. Do not leave it on past its time; a sheet that has gone dry takes moisture back off the face as it goes.
Worth knowing
- Patch test on the inner arm before first use on the face, especially if trying this brand or formula for the first time.
- Store away from direct sunlight and heat so the formula and any actives inside stay stable through its shelf life.
