Should the gauze in the grain rain cover be removed?

When using the patch mask, take out the mask first, then take off the gauze, and only use soft mask paper. Some masks are not put on gauze, but stuck on a piece of white plastic paper. White plastic paper is used to fix the shape of the mask. You can use it as long as you uncover it.

There is a fine cotton mask in this mask, but there is also a gauze. Gauze is not that effective. It can't be applied to the face as a mask, so when we apply the cotton mask to the face, there are still many nutrients on the remaining gauze, which can be applied to the arms or legs.
