Round Lab
In stock
A 50 ml ampoule built on black soybean, the Mungyeong crop that anchors this line and the same bean behind doenjang, the fermented paste that made soy a Korean daily staple long before it was a cosmetic ingredient, with panthenol and ceramides. The brand describes ten layers of hydration and a 120-hour moisture figure from its own testing.
Who it's for. Dry, dehydrated and barrier-compromised skin, and skin that feels rough rather than oily.
How to use. After toner, two to three drops pressed into damp skin, morning and night. Follow with cream to seal it. On very dry skin, add a second pass on the cheeks.
Key active. Panthenol, which converts to vitamin B5 in the skin, with ceramides and black soybean extract, working on water retention and barrier lipids.
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.
