Precision Brow Shaper®: Use the built-in brush to groom hairs into place. For the softest look, apply to areas of sparseness and blend. To create your ideal brow, always measure where you would like your brow to begin, arch, and end before outlining your desired shape and filling it in. Fuller Brows® Brow Mascara: Using short, upward motions, brush the precision applicator along the brow starting at the inner point and moving outward. To fill in areas of sparseness, use a gentle pressing motion while shaping and sculpting the brow. For the most natural results, always brush in the direction of hair growth.
