MAC's 187 Duo Fibre Brush
(Taken from the MAC website...)
"A large full circular brush used for lightweight application and blending of face powder or pigments. Use to create soft layers or add textures. Made from a soft blend of goat and synthetic fibres. 18 cm US$42.00"
This is how I was instructed to use this brush (as per MAC counter person..)
1. Wash face/ tone etc...
2. Use brush to apply moisturizer in circular motion all over face
3. Use brush to apply foundation in circular motion all over face
4. Use brush to apply powder to set in circular motion all over face
The result is a beautiful and flawless application of color. You look like you've been airbrushed. The beauty of the 187 Duo Fibre Brush is that you can quickly move from moisturizer, to foundation, to powder... you DO NOT need to change or clean your brush until you are done.
I use this brush with my Arbonne regiment... I love it! And I can apply my coverage super quickly, so I have no excuse not to look good! I also use the brush to apply a touch of bronzer (Arbonne) before my powder when I am flooking a little pale.
