Guerlain: expiration dates[ Edited ]
Hi Olesia - I can't stand it when expire info is so cryptic. I recently found out about what beautytester said about the 6 or12 meaning how many months a product is good after opening it. I didn't understand the codes you mentioned though. Sometims it minght say something like 28/12/13, which is more of a european dating system, I shouldn't say it's European because it's used all over the place. they put the date of the week, followed by the month of the year, and then the year.
But this one I don't get. I would get Guerlain's phone number from the website, and call them - or you could just email them. I usually prefer calling, sometimes you can learn a variety of things if the rep is nice and you sort of strike up a conversation or if you have questions about other products. Sometimes you can even get samples out of them.(not sure if Guerlain does samples though) I spoke to Guerlain once on the phone re: something I purchased and hated and they were wonderful about taking it back, very pleasant.
Hope they can help, hope you'll come back and let us know what you find out. Best of luck.
