Cara vs. rostro vs. faz
The Spanish words cara, rostro, and faz all translate to the English word face, but they belong to different registers and have distinct nuances. While cara is the most common and versatile everyday word, rostro is more formal and expressive, and faz is largely reserved for poetic or literary contexts.
Cara
A1The word cara is the standard, everyday term used to describe a person's physical face. It is highly versatile and can also refer to the face, side, or surface of an object, such as a coin or a geometric shape.

Faz
C1The word faz is a highly literary, poetic, and archaic term for the face. When applied to a person, it sets an elevated or dramatic tone. Today, it is most commonly used in fixed rhetorical expressions to refer to the surface or face of the Earth.

Summary
In summary, you should use cara for standard, everyday conversations and when talking about objects.

Finally, you should reserve faz for poetry, elevated literature, or established idioms like the face of the Earth.
