In short
To check a skincare product's batch number and expiry date in Bangladesh: (1) Locate the stamped or laser-etched alphanumeric lot code on the tube crimp or bottle base and confirm it matches the outer carton; (2) For Korean skincare, read YYYY.MM.DD 까지 as the expiry date and 제조 as the manufacture date; (3) For US/EU brands (CeraVe, The Ordinary, La Roche-Posay), use the 5–6 character lot code plus the open-jar PAO icon (6M/12M); and (4) Cross-check the SKU or lot code in Skinoly's Authenticity & Batch Hub (/authenticity).

In Bangladesh's hot, humid climate (where summer room temperatures frequently exceed 32°C–36°C), using expired or heat-degraded skincare can cause contact dermatitis, oxidized vitamin C staining, or failed UV protection. Yet different countries print dates and batch codes using completely different conventions.
1. How to Read Korean (K-Beauty) Expiry & Manufacture Dates
South Korean brands such as COSRX, Beauty of Joseon, SKIN1004, Anua, and Isntree print dates in the international `YYYY.MM.DD` order followed by Korean Hangul characters:
- 까지 (kkaji) or EXP: Means 'Until / Expiry Date'. Example: `2028.11.20 까지` means the unopened product expires on 20 November 2028.
- 제조 (jejo) or MFG: Means 'Manufactured On'. Unopened Korean skincare typically has a 30-to-36-month shelf life from the manufacture date.
- 개봉 후 12개월 (12M PAO): Means use within 12 months after opening the seal.
2. How to Decode US, Canadian & European Batch Codes (CeraVe, The Ordinary, La Roche-Posay)
Under US FDA and EU Regulation (EC) No 1223/2009 rules, cosmetics with an unopened stability exceeding 30 months are not legally required to print a calendar expiry date on the box. Instead, they print:
- Factory Batch / Lot Code: A 4-to-7 character code stamped on the bottle neck/base and carton bottom (for example, L'Oréal/CeraVe code `20X301` or DECIEM/The Ordinary code `DC-3K2`).
- PAO (Period After Opening) Symbol: An open cosmetic jar icon displaying `6M`, `12M`, or `24M`, indicating how many months the formula remains stable after first opening.
- Skinoly FEFO Ledger Solution: Because Bangladeshi buyers want explicit calendar expiry dates before ordering, Skinoly translates and logs the manufacture and expiry dates for tracked warehouse batches in our Authenticity & Batch Hub.
3. Japanese (J-Beauty) & Indian Skincare Batch Formats

Limitations of Third-Party Online Batch Calculators
Many consumers use free third-party websites (like CheckFresh) to look up batch codes. Be aware of an important limitation: third-party calculators only guess dates using generic letter-per-year formulas and frequently lag behind when a brand updates its factory coding format or opens a new regional manufacturing plant. Always rely on printed carton dates (`까지` / `EXP`), intact factory seals, and verified importer batch logs (/authenticity).
