A facial is a professional treatment for the face. Cleansing, steam, a mask, and forty minutes lying down.
Salons and spas offer them, and the noun is entirely everyday. The word is much older as an adjective, meaning anything to do with the face, which is where facial expression, facial hair and facial recognition come from. That last one has become a serious subject in law and privacy. Medicine has the facial nerve, which controls the muscles that make expressions.
