Check Dermarssance Cosmetic Batch Code
Dermarssance is a Seoul-based Korean skincare company known for sheet-mask and facial-treatment products. Korean packs often print a clearly labelled manufacture date and a separate expiry or use-by date, sometimes along the sachet seal. Reading the Korean label matters more than guessing from an unrelated barcode or product number.
Dermarssance FAQ
Which Korean word marks manufacture?
제조 or 제조일 indicates manufacture, while 사용기한 and 까지 relate to the use-by limit.
Is a barcode the batch code?
No. It identifies the retail mask and can repeat across production dates.
Dermarssance manufacturing dates on Korean masks
Before you rely on the decoded date
- Inspect the crimped top and bottom edges of a mask sachet, then the rear panel and multipack box for YYYY.MM.DD or compact Korean date text.
- Distinguish 제조 (manufacture) from 까지 or 사용기한 (use by). Do not subtract shelf life from expiry unless the package explicitly supplies that relationship.
Common lookup mistakes
- Photograph the sachet before opening because serum and torn foil can make the edge print unreadable.
- Discard a swollen, leaking or dry mask, or one with changed serum odour or colour, regardless of the printed date.
