Glossier Boy Brow Arch 2-in-1 Eyebrow Pencil — Cool Dark Brown, Dual-Ended Precision & Fill

Glossier Boy Brow Arch 2-in-1 Eyebrow Pencil in Cool Dark Brown is a slim dual-ended brow tool that creates hair-like strokes and fills sparse areas for a defined, natural arch.

Designed for quick, realistic shaping, this pencil combines a precision edge for fine flicks and a flat edge to lay down pigment where brows need density. The formula blends coconut-derived moisturizers and a botanical clay complex that helps pigment adhere while resisting water, transfer, smudging, and sweat. Lightweight and cruelty-free, the product is part of Glossier’s skin-first approach to everyday beauty and pairs seamlessly with Boy Brow gel to lock shape in place.

How does the dual-tip design improve brow definition?

The two-edge tip lets you mimic individual hairs with one side and block in color where brows are thin with the other, making shaping faster and more natural-looking than a single-tip pencil. Because one tool covers both microstrokes and filling, you can finish a polished brow with fewer products and less precision work.

• Precision edge: creates hair-like flicks for a delicate, realistic finish.
• Flat edge: fills gaps evenly to build visible density without harsh lines.
• Slim barrel: enables controlled application even in small brow zones.

Will the Cool Dark Brown shade work for my skin tone and hair?

Cool Dark Brown is formulated with neutral-to-cool undertones to complement darker brows that lean ash rather than warm brown or red. It harmonizes especially well with cool dark hair or when you want a defined yet soft look without warm or orange cast.

• Neutral-cool pigment: avoids warm/red tones for a more natural match on cool dark hair.
• Part of a nine-shade range: choose from black, greys, browns, and blonds for closer matches.
• Layer-friendly: build color gradually to fine-tune intensity.

How durable is the wear and how should I set the brows?

The clay complex helps the pigment adhere and resist water, transfer, sweat, and smudging without flaking, so brows stay defined through daily activities. For extra hold and a groomed finish, sketch and fill with Boy Brow Arch, then top with Glossier Boy Brow gel to set hairs and seal the look.

• Botanical clay complex: improves pigment longevity and hold.
• Resists water and sweat: suited for everyday wear and humid days.
• Pairs with Boy Brow gel: use gel to lock shape and increase hold.

How do I use Boy Brow Arch for a quick, natural routine?

Start at the inner brow with light hair-like strokes using the precision edge, progress toward the arch and tail with slightly denser strokes, then flip to the flat edge to fill sparse patches. Finish by brushing through with Boy Brow gel to blend and set the color and shape in place.

• Step 1: Lightly sketch hair strokes at the base and body of the brow.
• Step 2: Fill sparse spots with the flat edge for consistent density.
• Step 3: Set with Boy Brow gel for a natural, groomed finish.
