Sephora no. 45 Mineral Buffing brush
Or Sephora IT Buffing brush. they both work AMAZING for liquid or powder foundation.
I Have two of the no. 45. One for my MSF/BE and one For my MUFE HD. I sell it all the time for people wanting a streak free flawless finish. It even works with thicker foundations like the mufe matt velvets, which i find can be a cakey.
I absolutely looooove the Cover FX #160 Cream Foundation brush. It's marketed as a "cream foundation" brush, but honestly, I use it with a liquid foundation and it's amazing because it's dense enough to provide good coverage and buff it in. LOVE!
I use the Ecotools blush brush.. which has a compact head and is made of manmade fibre. I also like Sephora 55.. but I always buff with MAC 187.. so in essence I use two types of brushes for a really good app...
I have used several brushes for liquid foundation. I have tried MAC's 109 but found it sheds way too much. Now I am using MAC's 187 and loving it. Recently I saw a You Tube video raving about Coastal Scent's Buffer Brush, so I ordered it. I will let you know how that works.
187 was my favourite until MAC senior artist Caitlyn C. recommend that we try the smaller version - 187 it blends better over all the angles of your face.
she was right! LOVE IT!
I've been wanting to try the Sephora Airbrush foundation
Lately I've been using Lancome's Precision Foundation brush. It's not sold seperately; I got in one of their Holiday 2010 brush sets. It's awesome and gives me a great "airbrushed" look with absolutely no brush marks.
My MAC 130 duo brush i use it all the time at the counter and at home but outside of MAC my Sonia Kashuk multi purpose flat top brush or my beauty blender sponge
