Using these DUcare makeup brushes is a breeze. For foundation, dip the buffing brush into the product and gently apply it to your face in circular motions for a smooth finish. When using the eyeshadow brush, pick up the color and sweep it across your eyelids. To use the blush brush, smile and apply the blush to the apples of your cheeks. For the lip liner brush, carefully outline your lips before filling them in. When you're done using the brushes, clean them regularly. You can use a mild brush cleaner and lukewarm water. Gently swirl the brushes in the soapy water, then rinse thoroughly and let them dry flat. Keep the brushes in the leather holder when not in use to protect them from damage.
