I've put this foundation on a variety of ways and there's just NO WAY to mess it up. I've used only my fingers to dab & smooth it on when I'm in a rush, I've used a sponge applicator to smooth it on, I've stippled it on with the MAC 187, and I've even used the Shu Natural 18 Foundation brush to apply it. However you choose to apply this, it goes on beautifully. It gives medium to medium-full coverage and has a bit of a powdery finish.
What I love is that this foundation never cakes and it lasts through an 8 hour day. I don't recall ever needing to touch-up my face with this foundation. I've seem some forums where people say this foundation has oxidized on them and turned orangey. I tested it out and I didn't have a problem with oxidization but I also disagreed with the original shade the SAs picked out for me. They chose #754 for me but it was a bit off - so I self-corrected afterwards.
The only real complaint I have is I can "feel" the foundation sitting on my skin as it's drying. Even though it dries fairly quickly, every now and then during the day I get that feeling of The Foundation is ON again.
