What it is: A duo-ended two brush mascara, so no lash is forgotten. What it is formulated to do: Breathtaking brush N.1 boosts volume, length, and curl in the blink of an eye and Mini brush N.2 goes to the limits, taking in every lash. Guerlain's innovation is two brushes with amazing characteristics-so no lash is forgotten. The first brush transforms eyelashes with a single stroke while it lengthens, curves and separates. The second, miniature brush is designed for the inner and outer corners and tilted seven degrees to reach and grab the smaller eyelashes and make them up easily without smudges or mistakes. What else you need to know: The overall effect is perfect, precise, and voluptuous while also being supple and sculpted. The eye looks bigger and wider; the gaze brilliant.
