currently i have these concealer brushes in my brush collection. from left to right, by edm, sigma makeup, mac and ecotools.

close up view of the brushes.

i can't find edm concealer brush from the website. it's probably discontinued. i bought it to apply mineral powder concealer. powder concealers are bad for my fine lines so i don't use them anymore. nowadays when i'm using mineral powder foundation, i'll use this brush to dab the foundation (not concealer) on blemishes.

for concealing undereyes, i love ecotools concealer brush. it's bigger than other concealer brushes. it's perfect for my large dark circle area. i've been using this brush a lot since buying it a few months ago.

the mac and sigma's concealer brushes are quite similar. i don't know the number for mac because it's old and the number printed on the handle has faded. they're not bad. i use them more for concealing blemishes on my face than under eye area.
