External Appearance
Outward Appearance, Surface
noun
The outside face to something is the external appearance of that thing.
While 外面 can refer to the outer surface of an object, it’s more commonly used to describe someone's outward appearance, behavior, or demeanor on the surface.
This is a jukugo word, which usually means on'yomi readings from the kanji, so this is がいめん. But note that this can also use the kun’yomi readings, which makes it そとづら.
While がいめん is neutral, そとづら is a bit negative, often implying that the person's outward appearance might be deceptive, hiding their true nature.
