Here are some of the most popular Mineral Makeup Blush Brushes:
Bare Escentuals Tapered Blush Brush
This perfectly rounded brush applies, blends, and contours the blush to give
it a more natural flush of color to the cheeks. The soft, flexible, goat
hair bristles allow you to control the amount of color you apply.
The soft, tapered, goat hair bristles fit perfectly into the contours of the
cheeks for maximum, natural definition with bareMinerals blush or all-over
face color.
If you are looking for brushes from Bare Escentuals bareMinerals or other well
know retailers, look first on eBay, many users sell extra brushes from kits at a nice discount. Just make sure they are new and unused and the seller has great feedback.
