Once your order has been shipped from our distribution center, we will send you an email with your online tracking information. Use this information to track your order via the courier website linked in the email. If you have any trouble tracking your order, please contact us at global@cosrx.co.kr.

We do our best to make sure orders are packaged correctly but sometimes people make mistakes while picking or have problems during delivery. Any wrong or defective orders should be brought to our attention upon receipt. We may request additional photos of the damaged items so please do not throw them away until you have connected with our team.

Have you checked your tracking information? Please make sure to check your surrounding area and with your neighbours. If you’re unable to locate your package, please contact us so that we can start an investigation with the courier in regards to your missing parcel.

Once an order has left our distribution center, please note that it can take a few business days for some shipping operators to update further tracking details on their website. If you have further questions, please contact us at global@cosrx.co.kr.

We use various couriers depending on the destination, and as a result, shipping times may vary. Please note that the below shipping timelines are estimates and not guaranteed. We work as hard as we can to try to meet all delivery estimates, but sometimes there may be delays - e.g. because of parcel delays, logistics, bad weather, or things out of our control. If you have not received your order in the expected timeframe, please contact us and we will look into this for you.

* Currently, orders may be delayed due to the impact of COVID-19.
