Introducing the new generation of Yves Saint Laurent makeup brushes. The Y foundation brush is the perfect partner for Touche Éclat Foundation. You can customise your coverage using the 'Y reservoir' - simply pump foundation directly into the reservoir and blend in circular motions. 1. Pump Touche Éclat Foundation directly into the 'Y' reservoir; fill halfway for medium coverage or to the top for full coverage. 2. Dab on the cheeks, forehead and chin. 3. Blend in a circular motion from the centre outwards. 4. Use the side of the brush to smooth around the eyes and nose.
