If by the end of the day your look tends to be more Courtney Love than Courtney Cox, get set to widen those panda-eyes in surprise with news of Anastasia's latest launch. Lash Genius is a transparent, water-resistant top-coat that seals your mascara to leave your eyelashes shiny, separated and totally tear-jerker-proof. Feel smug come the end of 'The Notebook', un-phased in the face of a downpour and emerge from the pool looking pristine (not half-drowned). It's a new make-up must-have.
