I swore off foundation brushes years ago once I discovered the Beautyblender. However, ever since trying out the Bobbi Brown Precise Buffing Brush (£37), which launched this month, it's been back to brushes for me. The shape of this buffing brush is like nothing I've ever seen before; the densely-packed bristles are formed in a slight pyramid shape that, not only helps give your foundation an airbrushed quality, but also (similar to the Beautyblender) allows you to successfully blend your foundation and concealer in tricky areas like the corners of your eyes, sides of your nose, and under your bottom lip. I can't remember the last time I was this excited about a brush before.
