Flat Definer


The Flat Definer is one of our most used brush. Think of it as the mistake eraser to create defined lips and brows.


  • Contours nose: Creates strong, sharp lines on the sides of the nose with cream based products
  • Cleans and defines brows:  Use this brush with a concealer that matches your skin tone to clean up the area around your brows to hide stray hairs, giving the entire area a lifted look
  • Cleans and defines lips:  Using concealer, get as close as you can to the edges of the lips to wipe off excess colors on the outer corners. This helps your lips appear fuller and more rounded. If your lipstick is beginning to bleed, dip the sides of the brush is foundation and redefine your lips by retracing the outline.
