What it does: Gives a lift to the face by highlighting the brow bone and eye area. Why it's great: Brow Duality Highlighter instantly adds a lifted look to the entire eye area of all skin tones with a dual pencil with boast matte and shimmer sides for a day to night look. Brow Duality is designed for those who want the best of both worlds: Anastasia has married her customer favorites into one! Pencil features Matte Highlighter on one end and Shimmer Highlighter on the other. Bring subtle focus to the brow bone. Use the Matte side during the day to create a soft highlight. For those nights on the town, use the Shimmer side to give your eyes that soft satiny glow. How to use: Apply either Matte or Shimmer side directly along the brow bone underneath brow hairs. Blend up and outward using index finger. By Anastasia Beverly Hills.
