Does the pack have a separate expiration date?

I have doubts and I'm curious.
I don't feel like my face is that dry.

It doesn't cause much strain even without using a separate face mask or cream.

Is this just my own arrogance and insensitive behavior?

I don't feel the need to do it, so I use face masks on and off... my facial care is a mess.
Because of this, I have face masks lying around that I received as gifts or bought on sale, some of which are over 4 or 5 years old.

It hasn't been opened or damaged.

Does the pack not have a separate expiration date?

Is it okay to use this?
