Detailer Brush

Don't let the size fool you. The Detailer brush is one of the most versatile tools in the entire Signature 11 collection — and once you discover what it can do, you'll reach for it every single day. Use it as simply or as creatively as you like. At its most effortless, smudge a little shadow along your lower lash line to create a beautiful, soft powder liner — no liquid, no gel, no shaky hands required. Take it to the outer corner of your lid and build just a whisper of smokiness for a look that's sultry without being heavy. And then there's Kat's favorite trick — a tiny pop of highlight on the inner corner of the eye. That little twinkle that catches the light and makes your eyes look instantly brighter, wider, and more awake. Everyone notices it. Nobody can quite explain why. From the simplest smudge to the most polished detail work, this brush meets you exactly where you are.
