Eyeliner - Benefit's "They're Real"

  I love eyeliner and and been dying to try Benefit They're Real! Push Up Liner.  I'd read so much about it: it's a matte black gel formula with a 'pen' that makes it easy to get close to the lash line. I was most curious to find out if it really didn't smudge or dry out as it's a waterproof formula. So thought I'd put it to the ultimate test. I used the eyeliner at 10am and was flying back to London on a 10pm flight arriving mid morning so I'd have the same eyeliner on for at least 22 hours, and although I did look a bit tired after my flight I didn't have smudged or messy eyeliner after my trip!
