COSRX
In stock
A viscous 40 ml ampoule using three molecular weights of hyaluronic acid at once, the high weight sitting on the surface and the low weight sinking further in. It looks sticky in the dropper and is not on the skin; it flattens out in a few seconds.
Who it's for. Dry and dehydrated skin, and skin that looks flat by mid-afternoon.
How to use. After toner, press two or three drops over face and neck while skin is still damp, since hyaluronic acid needs water to work with. Seal with moisturizer. Morning and night.
Key active. Hyaluronic acid in high, medium and low molecular weights, humectants that bind water at different depths of the surface layer for a plumper look.
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.
