Buff on bareMinerals fast and flawlessly with the firm, full, luxuriously soft tapered brush that gives full, perfectly controlled application in record time. Use with bareMinerals SPF 15 Foundation for full coverage. My Tips This is a great stable brush for maximum coverage. I would recommend washing your brushes every month, 2-3 weeks if you have acne, ideally with Well-Cared For Brush Conditioning Shampoo.
