Decencia FAQ
Where should I look for the Decencia lot code?
Check the carton flap, the bottle base and the sealed tube end; the position can differ by container, market and production run.
Can the Decencia code confirm expiry or authenticity?
For the product in hand, use it as one production clue, not proof of shelf life or authenticity; labels, condition and source remain decisive.
Where DECENCIA prints skin-care lot information
Before you rely on the decoded date
- On Decencia products, inspect the carton flap, the bottle base and the sealed tube end. Copy letters, digits and leading zeroes exactly as printed.
- Names such as Ayana, Saeru, Tsutsumu identify products or collections rather than manufacturing lots. Retail identifiers such as product reference, volume and barcode should not be mistaken for a Decencia manufacturing mark.
Common lookup mistakes
- Decencia products are sold in Japanese skincare formats such as pumps, tubes and refills. Keep the refill pouch or carton until its printed line has been compared with the container's compact code.
- For the product in hand, a lot estimate is secondary to printed dates and PAO; storage, opening history and product condition complete the decision.
