Blush Brush - pull the retractable arm up 1/3 of the way and use it as a blush brush to highlight the cheekbones with a little more concentrated coverage. Contour, Shading and Concealer Brush - pull the retractable arm up 2/3 of the way and use bronzer colore to contour on the cheekbones, jowl lines and eye area for the most concentrated coverage and detailed application. You may also use this brush position to use the foundation colore as a concealer.
