One of ZOEVA's best brushes IMO. I really wish I'd found this earlier, it has made such a difference when applying and blending cream and liquid products. The bristles are synthetic and densely packed into a round fingertip-sized brush head, they aren't rigid but neither are they too soft and flexible either. As they are synthetic, they don't soak up and absorb products, and are easy enough to clean. I've had a few brushes with dense synthetic bristles that are a pain in the rear end to clean properly (I'm looking at you, Shiseido 131) but this washes easily with baby shampoo or brush cleaning spray and bristle tips go back to their original pristine white. There is very little shedding, despite me washing it frequently, and holds its shape well.
I like using this to apply and blend concealers on the undereyes, sides of nose, around my nose bridge and softening harsh lines in these areas as well as blending base make-up around brows and lips for a more soft-focus appearance. It also works nicely to blend cream contour around the eyes and nose, although I find if used to apply it as well, it goes on too strongly, so I only use to blend. It's too small to apply cream blush, unless used to blend a dot of darker colour near the centre of a lighter one. But it is great to use with cream and liquid highlighters on smaller areas like the brow bone, nose bridge, chin, and cupid's bow.
What I don't find it so helpful for is concealing blemishes - at least if used alone. I prefer pinpoint concealing with a tiny brush, but if I need to blend edges of a larger blemish it's helpful in that sense. Otherwise, the diameter of the brush head is too big for isolated spots here and there. I also don't really like using it with powder products, it has a tendency to leave powdery streaks and some patchiness.
But overall, this is a wonderful brush. it has significantly cut down the time it takes to do my make-up before leaving the house. Will definitely repurchase if I lose it!
