Laura Mercier Caviar Tightline Eyeliner in Dark Plum. It almost looks like a grayish-purple-black - so pretty. Reg is $29. Details & care What it is: A smooth, gel-like eyeliner pencil that glides on easily to perfectly line the tightline, lashline and waterline for waterproof, creaseproof wear. What it does: This creamy formula provides 16-hour pigmented, long-wearing, waterproof wear that won't tug, smudge or transfer. Enwrapped in hyaluronic acid, it applies smoothly, provides ideal playtime to smudge, shape or correct before it sets, and is available in pigmented shimmer and matte finishes.
