Some of my favorite brushes that I use daily are Morphe brushes. They have this awesome program where you pay $19.99 a month for 3-5 brushes. I recommend this program to artist or enthusiast just starting out and need some good inexpensive brushes. Or for the pro artist who loves extra brushes.
The R5 pro contour brush is what its name says. The bristle on this brush is very soft. The tapered point is ideal for someone who is a beginner in contouring. The hair starts off with a fuller base which is suitable for blending out the edges of the contour. Sits perfectly underneath the cheek bone.
The R37 pointed blender is a fave of mine. Its tapered bristles are perfect for carving out the crease area. This brush acts as a contour brush, like the R5, but for the eyes. Good for blending out shadows. Or for creating depth in the crease area.
The R41 pencil crease is perfect for those cut creases. I would also use the brush to add color on the bottom lash line. The R41 helps with precision. To define your crease even more or to add a little contrast to the lower eye.
The R38 round blender is perfect for your transition colors. Its fluffy shape diffuses color to be evenly distributed. You can also apply concealer with this brush. I know it may come as a shock. The frame of the brush blends out concealer, shadow, and even foundation. You would use it on smaller areas.
