What is it: A creamy, intensely colored eyeliner duo that glides on with easy fluidity.Who is it for: Suitable for all skin types and tones.Why is it different: This eyeliner duo helps you create a smooth, flawless line with a sexy, smudgy look. The buildable formula gets darker with every layer.How do I use it: Stroke a slanted eyeliner brush across the surface and apply along top and bottom lash lines in continuous little pat-and-press steps. Extend and lift slightly at the outer corner. If a finer, darker line is desired, choose a skinny brush and stroke on wet.From Laura Geller.
