According to Pascal Cotte, a Parisian engineer, Mona Lisa once had eyebrows and eyelashes.

(He dedicated around 3,000 hours to examining Leonardo Da Vinci’s famous portrait and says that years of restoration work have eroded the facial hair. Using 240-megapixel scans, Mr Cotte, 49, says he can see traces of a left eyebrow long obscured from the naked eye by the efforts of the restorers. I wouldn’t want my face examined on a 240-megapixel scan!  They’ll be saying she had a moustache and beard next. Please, gentlemen, let us ladies have our little depilatory secrets.)
