The phrase "giving a facelift" implies the act of improving or enhancing the appearance of something or someone. The antonyms for this phrase include damaging, defacing, disfiguring, and ruining. When a property or a building is subjected to vandalism, it results in damage and defacing, rather than a facelift.
