Only the area around my mouth is unusually white and flaky.

hello.

My skin isn't even dry, so why is the area around my mouth like that?

I am diligently using serum and cream morning and evening, but I am worried because my skin is not improving.

Even after patting eye cream onto the nasolabial folds, the dry feeling remains the same.

Will it get better if I apply a face mask every day?

The cream I apply in the evening is Isoi T-Reference.
