Do you always check the expiration date of face masks?

Whether it's food or cosmetics, the expiration date is

I understand that it literally means the period during which it can be distributed and sold.

Since the usage period isn't specified, I'm wondering how long it's okay to use.

I don't have sensitive skin, so I think it's okay to use even after the expiration date, but I have absolutely no idea how long that should be.

Do you all make sure to check the expiration dates on your face masks?

If anyone knows the shelf life of face masks, please share.
