L'Essentiel Retractable Foundation Brush

What it is: A synthetic-bristle retractable, flat-top foundation brush that provides smooth, even foundation application.

What it does: Ideal for use with foundation products, this soft brush features a retractable sleeve to protect the bristles while also making it ideal for everyday use, travel and touch-ups. It's designed to work in hard-to-reach areas, such as underneath your eyes, while leaving a streak-free finish.
