With some mascaras, the formula's great but the wand is hard to use, or the wand is fabulous but the formula flakes and smudges. The new Laura Mercier Caviar Volume Panoramic Mascara (£22) is an example where both brush and formula are incredible. The formula is shiny, flexible, and doesn't leave behind little flecks under your eyes throughout the day, all while giving you long, thick, lush lashes. The brush, on the other hand, is twisted like a DNA helix, which makes it super easy to catch your lashes at the root and then roll the wand through them to really deposit each and every bit of pigment possible onto every lash.
