In the Middle Ages there was a branch of sorcery known as "glamour". A magician using that could give something a completely different appearance. Merlin did it for Uther Pendragon when he wanted to seduce the Lady Ygraine; the evil gnome did it in "Lay of the Last Minstrel" when he appeared as the son of a noble house.
Are our present beauticians also working magic? What happens when the make-up comes off?
