EXCLUSIVE to Harvey Nichols. Blinc Eyeliner was created to form a water-resistant layer of colour that contours your eyes. Since Blinc is not a cosmetic paint like conventional eyeliners, it cannot fade, smudge, run or flake, even if you rub your eyes. Only when you are ready for removal, the layer of colour will effortlessly slide off your skin into your hand without the use of a harsh make-up remover.
