Laura Mercier Dispense one to two pumps onto the back of your hand. Using a dense buffing foundation brush, press the flat end of the bristles into the product and tap on the back of the hand to disperse the product evenly into the bristles. Apply onto clean skin in sweeping motions to blend. Use the tapered end or a smaller brush to blend around the nose and smaller areas. For optimal wear, this foundation works well with silicone-free primers. After finishing, set with your preferred setting powder (sold separately). Foundations
