Date of minimum durability (the hourglass)

Stored as the pack says, the product will keep working as intended and stay safe until the end of the date shown. The law requires it on cosmetics that keep for 30 months or less.

How to read it

The date is written month then year (or day, month, year, in that order), so 03/2027 means the product is covered until the end of March 2027. The hourglass can also stand in front of words saying where the date is printed, for example on the crimp of a tube. If the pack adds storage conditions (‘store below 25 °C’), the date only holds if you follow them.

What it does not promise

It does not promise how long the product keeps once opened: the date is about the product ‘stored under appropriate conditions’ and says nothing about the time after first opening. It does not promise the product is unsafe after the date either: it is the last date the maker guarantees. A pack with no hourglass is not missing its date if it shows the open jar: that means the maker declares a durability of more than 30 months.

This page explains what a symbol or mark on the pack means in law or in the scheme’s own rules. It is not advice on whether a product or an ingredient is safe for you or suits your skin: for that, read the product’s warnings and ask a pharmacist or doctor.

What it looks like
An hourglass with sand in the lower half, followed by a date: a month and year (08/2027) or a day, month and year. Some packs print the words ‘best used before the end of’ instead of the hourglass.
Legal reference
Regulation (EC) No 1223/2009, Article 19(1)(c) and Annex VII point 3
Also called
best before end symbol; hourglass symbol on cosmetics; expiry date symbol

Good to know

The same hourglass drawing is used on medical devices, where ISO 15223-1 gives it a different meaning: a use-by date after which the device is not to be used. On cosmetics it is a best-before date.
