The shelf life of jm mask is different when opened or unopened

How long is the shelf life of Jm masks? There are so many types of Jm masks, and many fairies want to know whether the shelf life of so many masks is the same? So here is to tell the fairies the shelf life of each Jm mask, let's take a look~

Jm mask shelf life

Unopened shelf life

Jm masks are divided into three types: sheet masks, soft masks and sleeping masks, but the unopened shelf life of these three masks is three years. That is, as long as it is unopened, the Jm mask can be stored for three years~

Shelf life after opening

The shelf life of Jm masks after opening is different. For example, Jm sheet masks and soft masks need to be used immediately after opening, while Jm sleeping masks can be used within one year after opening. This is because the mask will come into contact with bacteria in the air after opening, which will accelerate the oxidation of the effective ingredients in the mask, causing the Jm mask to lose its effectiveness faster, so the shelf life of the Jm mask will be shortened after opening.
