Frequently Asked Questions
You've got questions, we've got answers
What is the difference between Brow Pop Dual-Action and Brow Pop Nano?
Both are long-wearing, super easy-to-use brow pencils designed to create your perfect shape. Brow Pop Nano has an ultra-fine 1 mm tip for drawing realistic, hair-like strokes and detailing the tiniest sparse spots. It gives a soft, clean, natural look—perfect for adding believable texture or refining edges. Brow Pop Dual-Action features a dual-sided, triangular micro-tip with a thicker edge for filling in larger sparse areas and a thinner point for definition. It’s ideal for shaping fuller or over-plucked brows. Use them together for the ultimate customized brow—define with Dual-Action, then detail with Nano.
How small/thin is the pencil?
Brow Pop Nano has an ultra-precise 1 mm pencil tip, one of the smallest available, so you can mimic real brow hairs and achieve ultra-natural definition.
Is Brow Pop Nano waterproof?
While it’s not fully waterproof, Brow Pop Nano is smudge-proof, transfer-resistant, and sweat-resistant. In a consumer study*, 100% agreed it stays put and stands up to water and sweat throughout the day.
How can I use Brow Pop Dual-Action and Brow Pop Nano together?
Start with Brow Pop Dual-Action to outline your brow shape and fill in larger sparse areas. Then use Brow Pop Nano to add fine, feathery strokes where you need extra detail—like the arch or tail. Finish with Air Brow Clear or Air Brow Tinted Gel for flexible hold and volume.
What is the best way to apply?
Brush brows upward with the spoolie. Twist the pencil up slightly—just enough to see the tip. Use light, short flicks to mimic natural hairs, focusing on sparse spots. Blend gently with the spoolie. For a full Kosas brow look, layer with Air Brow for tint, volume, and hold.
Is the finish matte or shiny?
It leaves a natural, soft finish—not shiny or powdery—so brows look full and real.
Does this require sharpening or does the tip stay fine?
No sharpening needed! The retractable pencil design keeps the fine tip precise and ready for effortless detailing every time.
