化粧 (kesho), that means to put make up on and to decorate the inside and the outside of buildings, is said to have had its kanji changed from 化生 (kesho), which means to come into existence in a converted form as a consequence of one's past actions, because the acts of putting make up on and decorating buildings means to change towards something more beautiful.
本来の素顔や建造物の内装・外装を、より美しく変化するための化粧であることから、化生（けしょう）から化粧（けしょう）になっとともいわれる。
