I'm wondering about the appropriate time to apply a face mask.

There are also various types of face masks,
Among them, if you attach it and time passes
I used a mask pack that becomes transparent.

Some people do it for so long that they can even sleep with it attached.
People say it's good, and some say it's best to do it for 1-2 hours.
It seems like it absorbs the longer you leave it on.
I felt dryness even before it became completely transparent.

I think it might vary depending on the product, though.
Is it supposed to be dry...? I saw in the reviews that it was super radiant.
For me, it just felt dry. I wonder how long the appropriate time would be.
It feels like it wasn't absorbed at all since it was short, so it's a bit ambiguous.
