Kevyn Aucoin The Precision Sharpener

So much more than just a brush to sculpt and contour, it is ideal for when you have the time to make the complexion look really flawless. I use this to diffuse all the cream-based products together, including foundation, blushers and highlighters - it really helps to make the skin look flawless. I personally wouldn't use this for powders, as described, but it's ideal for building up coverage in smaller areas and giving an almost airbrushed finished to the skin. Great for diffusing pinpoint concealers too. My new favourite brush!
