Packaging for both are the twist click style with brush top, just like the Stila Lip Glazes. They feel about the same size actually, with Stila holding just a tad more of product, which makes Stila outrageous since it's a lip gloss and you'll use a whole lot more with each application. With this VS concealer, I only use dabs each time, so it'll last me quite a while.
The unscented formula neither thin nor runny, but it does dispense a soft cream texture. So what I like to do is to dispense just a tiny bit before I recap, so that by the time I use it next it would have thickened somewhat, providing better coverage than when it's softer and creamier. And while it does a decent job with concealing, I wouldn't say it "brightens" anything at all. The finish is matte without any shimmers, and being "light" it's actually medium - see the swatch, it's a couple of shades darker than the back of my hand! It also oxidizes and turns slightly pinky. So no, it doesn't brighten, only conceal.
