What It Is: Designed with a narrow, ultra-precise head and synthetic bristles, our new Concealer Brush makes it easier than ever to achieve flawless undereye coverage. Perfect for use with our Corrector and Concealer formulas. Why It's Different: The secret to looking wide-awake is lightening and brightening undereye darkness - especially in hard-to-reach areas like the inner corner of the eye and under the lash line. With its compact design and narrow head, the new Concealer Brush lets you maximize the effect of our Corrector and Concealer formulas. How To Use: Use the Concealer Brush to apply Corrector as close as possible to the lash line, and also on the innermost corner of the eye. Gently blend with your fingers. Follow with Concealer.
