Japan Expiration Date
Japan Expiration Date
Japan's Pharmaceutical and Medical Device Act (formerly known as the Pharmaceutical Affairs Act) states that it is not necessary to display an expiration date, except for cosmetics that deteriorate within three years of manufacture. Once opened, cosmetics should be used up as soon as possible. If you want to use them again next season, avoid places with high temperatures and humidity or large temperature changes.
Some brands choose to include:
-
-
A "Period After Opening" (PAO) symbol — e.g.,
12Mmeaning “good for 12 months after opening.” -
A batch or lot code, which lets the manufacturer track production and recall items if needed.. The batch code can be checked directly with the manufacturer.
- In the EU, cosmetic law requires either an expiration date (“Best before”) or a PAO symbol.
-
We make the effort to contact each manufacturer about their shelf life and PAO ( Period after opening), and this information is added to the Product Page. If you prefer their official communication, please don't hesitate to contact us at cosmeticeantiaging@gmail.com to provide a copy of such confirmation.
