When you think of an eye pencil, eyeliner is probably the first (and maybe the only) thing that comes to mind. But considering I'm a liquid liner user, the Chanel Sculpting Eyebrow Pencil ($29) is the only eye pencil in my everyday makeup bag. I love that it not only has the perfect amount of brow pigment on one end — it goes on light, but totally buildable — but it also has a spoolie brush on the other end. This makes grooming and filling in my brows fast and easy.
The one makeup artist tip I love is to find a color one shade lighter than your natural color is so it subtly shades without making it overpowering. And in case you think you don't really need to fill in your brows, once you try it, you won't feel the same without nicely groomed brows.
