It can be used, as long as it doesn’t deteriorate. The shelf life of cosmetics is only a rough estimate and cannot be accurate.

For example, the shelf life abroad is five years. If you buy it domestically, you have to bid for three years because the laws are different. But the stuff is the same.

Do you think things are considered expired after three years or not?

So as long as it doesn’t deteriorate, it can be used, and you don’t have to worry about the shelf life.

Of course, if you are not worried, you can apply it on your body. Moreover, if there is a problem with a product that has passed its shelf life, the manufacturer will not pay compensation.

If you store some things improperly, they may go bad before the expiration date. That's also unusable. Therefore, judging a product depends on whether it has deteriorated, rather than just looking at the shelf life.

No one’s shelf life can be so accurate. They are all canned during production, and you don’t know how many days they have been stored. There is no one to hold your watch to check the time.
