A moisturizing cream doesn't last forever. Like any cosmetic product, it has an expiration date that is important to respect, both for the effectiveness of its active ingredients and for the health of your skin.
A changing texture, an altered odor, or even invisible bacteria can transform your beauty routine into a minor dermatological risk.
So, how long can you actually keep your moisturizer on ?

The difference between DLU and PAO: two key points to know
-
BEST BEFORE END (Use By Date) : This is indicated on some unopened cosmetics. It is the date until which the product is guaranteed to be stable and effective.
-
PAO (Period After Opening) : Represented by a small open jar followed by a number (e.g., 6M , 12M , 24M ) as you will find on our Blue Skincare packaging. This means that the product can be safely used for 6, 12, or 24 months after opening .
On average, a moisturizing cream can be kept for 6 to 12 months after opening .

What are the signs that it's time to throw away your cream?
Even if the PAO (period after opening) is not reached, certain signs should alert you and prompt you to put your moisturizer aside:
-
The texture has changed (more grainy, more liquid, lumps forming)
-
The color has changed (yellowing or discoloration)
-
The smell becomes unusual or unpleasant
-
Tingling or redness may appear after application.
In this case, it is best to stop using it immediately.
How to extend the life of your moisturizer?
When you love something, you don't count the cost! And we love that our jar of Crème de Nacre lasts a little longer.
A few simple steps can help your skincare product last longer:
-
Close the jar or tube tightly after each use
-
Avoid dipping dirty fingers directly into the jar: make sure to use the product with clean hands
-
Store the product in a dry, temperate place , away from heat and direct light.
-
Respect the dates indicated on the packaging.
The unique nature of Blue Skincare products
At Blue Skincare , our BIONACRE® -based products are formulated to be effective and safe while respecting sensitive skin, and we always recommend using them within 6 to 12 months of opening to guarantee optimal effectiveness (although they are often finished sooner!).
Each product features a small pictogram of an open jar, followed by a number of months (e.g., 12M). This indicates how long the product can be safely used after opening.
