In fetish media, women are most often the people in masks. Objectified, which is the same as dehumanized, and hypersexualized, a state that cannot be achieved without objectification.
Their expressions are negated and their unique features are also negated. "Beauty" in the manufactured absence of beauty again.

Sometimes, women actually
become the mask.

(And it has happened that a mask
became a woman. To some people,
there is no difference.)
