COSRX Production History Verification

Please check the manufacturing number and expiration date on your product and submit them according to the items below to confirm whether your purchased product has a production history from COSRX.

The location where you can find the manufacturing number and expiration date by product type is as follows:

• Jar/Dropper/Pump type products: Bottom of product
