Round Lab
In stock
An 80 ml rinse-off mask with silver birch sap, hyaluronic acid, allantoin and betaine. A wash-off pack is the Korean weekly step for people who dislike sheet masks: ten to fifteen minutes, no fabric, no waste, and you control the thickness of the layer.
Who it's for. Sensitive skin prone to dehydration, and skin that feels tight and flat after a hard week.
How to use. Once or twice a week. Apply an even layer to cleansed skin, leave 10-15 minutes without letting it dry hard, and rinse with lukewarm water. Follow with toner and cream.
Key active. Silver birch sap with hyaluronic acid, allantoin and betaine, humectants and soothing agents, with no acid and no clay in the base.
Sourced in Seoul. This is the Korean domestic SKU, not a reformulated export version.
All orders ship from South Korea. Your order is picked and packed by our logistics partner in Bucheon-si, Gyeonggi-do, then travels to the United States as an international shipment.
Handling 1-3 business days, international transit and customs clearance 7-11 business days. Total estimated delivery 8-14 business days. These are estimates, not guarantees.
Free shipping on orders $120+; a flat $12.99 below that. The $120 threshold applies to your order total after any automatic discount. Product prices do not include U.S. import duties or customs fees, which are billed by the carrier and are the responsibility of the recipient.
You may request a return within 30 days of delivery on unused, unopened items. Returns ship to our facility in South Korea and require a Return Authorization Number, which you must request from us before sending anything.
The full ingredient list (INCI) is printed on the product packaging. These are authentic Korean-market formulations sourced directly in Seoul - the domestic SKU, not a reformulated export version.
