This brush (190 brush from MAC) is the best brush that I've used to apply foundation! Before this brush I would use anything to apply my makeup. Once I found out about this brush. I threw every crappy brush/pad away. This brush applies your foundation so evenly onto your skin. I promise once you use this brush, you won't want to use anything else!!!
Duo Fiber Faced Brush #187 MAC foundation brush is a must when I'm applying any foundation or powders. Evenly apply either your powders or foundation with this little man and you'll be glad you did! I bought my at a Nordstrom, but you can find this at almost any mall.
