I have under eye dark circles .. n hav used many concealer brushes and my search ends here ... this is really soft and blends very easily .. totally worth
I can blend my foundation, concealor and other liquud products.
I use the brush for concealer as well as foundation. The brush blends the products really well, does not absorb too much of the product which is great.
Didn't find the shape very helpful for blending under eye area, but for spot concealing on the face it is good
