Apply a small amount of Corrector on the back of your hand or a spatula. Use a slanted brush to fill in any sparse areas, then blend for a natural result. Use a fine brush to make very precise corrections hair by hair, or for the brow tip. Remove with a waterproof eye makeup remover. Brows that are too dark can make the eyes look severe.
To fill in a gap, dot a small amount of product on to the skin with the tip of the slanted brush, then work it outwards using the full width of the brush.
