Shiseido batch codes notice
February 20th, 2014

We got unverified notice saying Shiseido does not include production date information into the batch codes anymore. Instead, they generate unique character sequence for each batch, and record correlation between production date and such batch code into the databases. If this information is correct, it’s possible to identify manufacturing date of a product only having an access to the company internal databases.
As previously mentioned, this information is unconfirmed. We’re trying to clarify and verify it. Until this will happen, support for Shiseido has been removed. We’re sorry for inconvenience.
Please contact us if you have any information regarding Shiseido batch codes.

• 那就是之前出的还是一样啰？不懂这些化妆品公司干嘛不明写日子，难道是担心几年卖不出去？我觉得大商场买的没什么好纠结的 -呆西- ♀ (125 bytes) () 11/04/2014 postreply 14:58:41
