MAC Pro Brow Definer 1MM Tip Brow Pencil - # Brunette 0.03g

Meet the MAC Pro Brow Definer 1MM Tip Brow Pencil in Brunette — a precision tool built to sculpt brows that look naturally full, day after day. This is more than a pencil; it’s a grooming system that textures, colors, and shapes with salon-like accuracy.

1mm precision for hair-like definition

The ultra-fine 1mm tip creates delicate, individualized strokes that mimic real brow hairs. Each application builds a natural, layered look without heavy lines, so your brows frame your face with subtle, believable depth.

Dual-ended convenience you’ll actually use

One end houses the precise pencil, the other houses a built-in spoolie for grooming and blending. No need to switch tools mid-routine—glide from shaping to diffusing in seconds for a polished finish that reads as effortless.

Shade Brunette that flatters a wide range of brow tones

Designed to complement a broad spectrum of hair colors and skin tones, this shade delivers true color payoff without looking too harsh, even with light layers. The result is brows that look consistently natural, whether you’re aiming for a soft daily brow or a more defined contour.

Weight and control you can feel

At just 0.03g per pencil, you gain exceptional control for precise, refined filling without oversaturation. The lightweight formula is easy to feather and adjust as you go, so you can dial in your perfect level of intensity.

Conditioning formula for healthier, happier brows

Infused with a nourishing blend of castor oil, argan oil, and coconut oil, the pencil conditions as it colors. This reduces tugging and breakage during everyday grooming, helping maintain brow texture and shine while you define them.

Long-wear, smudge-proof performance

Designed to resist running and fading—rain, sweat, or shine—so you can trust your brows to stay put from morning meetings to evening plans. The combination of precision tip, conditioning oils, and resilient color payoff means you don’t have to reapply frequently.

Versatile for every brow type and every look

Whether you’re after a soft, airy finish or a bolder, more sculpted contour, this pencil delivers buildable color and seamless diffusion. It adapts to thinning brows, fuller brows, or in-between shapes, making it a reliable tool in any makeup routine.

What makes it uniquely effective

• 1mm tip for ultra-fine, hair-like strokes that mimic natural brow hairs
• Built-in spoolie for instant grooming and blending
• Conditioning blend with castor oil, argan oil, and coconut oil for gentle daily use
• Smudge-proof and waterproof wear that lasts all day
• Buildable formula that delivers true color payoff without harsh lines

Practical tips for the best results

Tip the pencil with light pressure to lay down a base of natural color, then switch to feathery strokes to mimic individual hairs along the natural brow arch. Use the spoolie to blend upward and outward for a diffused finish, or with a firmer hand for a more defined contour. Finish any look with a gentle comb-through to ensure even distribution and a cohesive shape.
