Cosmetic dates and the open-jar symbol: keeping track of your products
Distinguish the purchase date, packaging information and time since opening so your shelf is easier to manage.
Read the marking on your own packaging
The date you bought a cosmetic, the date printed on its packaging and the time since opening are different pieces of information. EU cosmetic labelling distinguishes minimum durability from the period after opening. For products lasting more than 30 months, a period-after-opening indication generally applies where that concept is relevant.
An open-jar marking such as 12M means twelve months after opening, not twelve months after ordering or the first time you remember using it. Do not assume the same period applies to every product or variant. Read the actual label and storage instructions.
Record opening while the date is clear
Use a small label or a phone note at first opening. A useful record needs only the product name, opening date, the packaging indication and storage location. Keep receipts separately rather than treating a purchase date as proof of when a bottle was opened.
If you do not know the date, record that honestly instead of reconstructing an exact day from memory. Photograph the original packaging and batch details if you need help interpreting a marking.
Store according to the product instructions
Reparex product guidance calls for appropriate storage, including keeping the relevant variant dry, dark and out of children’s reach. Check your own leaflet. A shelf regularly splashed by the shower is not suitable merely because it is convenient.
Keep the product identifiable in its original container. For travel, ensure it is securely closed and that instructions remain available; do not pour a remainder into an unlabelled spare bottle. Ask support if a marking has rubbed off or a code is unclear, and state which variant you have.
Separate opened products from reserves
Keep products currently in use apart from unopened stock and check dates before opening another bottle. This is an organisational habit, not a reason to increase the dose to empty a container sooner. Amount and frequency still come from the instructions.
A short shelf review supports a clearer hair-care routine: you know which product you are using, when you opened it and where to find the relevant guidance. When uncertain, contact our team rather than borrowing a date from a different cosmetic.
