5 Eyebrow Transformations, 1 Brow Pencil

THE CHALLENGE: Fill in sparse eyebrows using one multitasking tool. "Brush brows up with a spoolie," says makeup artist Nigel Stanislaus. "Then use the pencil for precision to define the tail and fill in any sparse spots. Go over your work with the powder, which will soften the look." The pencil comes in four shades: soft brown, deep brown, auburn, and blonde (these women all used a shade of brown). As these stunning before-and-afters demonstrate, full brows have the power to change your whole face.

THE SECRET WEAPON: Maybelline New York Eye Studio Brow Define and Fill Duo, a multitasking brow tool with a pencil on one end and a powder (with a built-in sponge applicator) on the other.

THE CHALLENGE: Fill in the gap and boost overall fullness.

THE VERDICT: "I've been brushing my brows up since this photo shoot! It makes my brows look more alive and distributes my hairs more evenly. When I do that, I don't need to draw in as much."

THE CHALLENGE: Amp up brows to help them frame her beautiful eyes.

THE VERDICT: "These arches look full, natural, and effortless, especially because I'm not wearing much makeup on my eyes. But I can see how they would complement a full face of makeup, too."

THE CHALLENGE: Showcase her high natural arch.

THE VERDICT: "I've been wearing them much thicker than usual since seeing what a difference it makes! I don't brush them to perfection, though. I like to leave them a bit wild."

THE CHALLENGE: Shaping her arches. "Even when brows are 90% there, a bit more definition dramatically lifts the face and cheekbones," Stanislaus notes.

THE VERDICT: "Great brows really do make you look put-together and sexy. I usually don't wear much makeup, just blush, eyeliner, and mascara. Now I've added an eyebrow pencil into my routine."

THE CHALLENGE: Add depth and fullness to sparse areas.

THE VERDICT: "I felt like a mega babe! Since the shoot, I've been recreating the full look for nights out."
