so after watching some influences promoting a long lasting eyeliner, I went and bought the Hourglass voyeur waterproof one, telling myself this is the last time I do this, as others I brought have failed me, well I am impressed, I will say in the water line where others included C T, last around 10 minutes, this one yesterday, I put on at mid day, and when I took it off a 10pm some had worn off but there was a little still on, today as I put it on under the lash line around 9am and now 5pm, it's not moved at all, I can't quite believe I have found my holy grail.
