What it is: A foundation smoothing brush that offers maximum application control. What it does: Designed by Peter Philips, Dior Makeup's creative and image director, this brush combines the smoothing power of a brush with the blending power of a sponge. Its ergonomic shape allows for maximum control, while lush, dense bristles leave skin with an even, airbrushed finish. How to use: Apply your foundation to the brush. Apply to skin, working in circular movements from the center of your face outward. Gently dab onto the areas of the face that require additional coverage. Clean using a brush cleanser or damp cloth. Avoid running under water.
