What it is: A long-wear brow pencil with a retractable, high-precision tip that allows you to redefine and fill out the brow line to perfection.What it does: Brow G offers easy and natural application thanks to its double-ended design, which combines a precise retractable tip and a spoolie brush for blending.Pro tip: 'For naturally defined eyebrows, I draw microstrokes in the direction of hair growth with the fine tip of Brow G, then brush them to blend the material and mimic the natural texture of my eyebrows.' - Violette, Guerlain makeup creative director
