Dispense a quarter-size amount of foundation to the back of your hand. Pick up a small amount using the buffer airbrush finish bamboo foundation brush and brush onto your skin, starting at the center of your face and blending out. Achieve a flawless, even complexion by soft circular buffing sweeps. To clean the brush: Run the bristles of the makeup brush under warm running water, avoiding the handle. Apply a small amount of shampoo to bristles and work into a light lather. Rinse bristles thoroughly under running water and continue rinsing until water runs clear. Gently squeeze excess water out of bristles and place on a level surface to air-dry before next use. Clean brush as often as needed.
