Purchased Aura a few days ago and am very impressed. It stays strong all day and isn't overpowering.
It is a distinctly pinky-lilacy highlight, very different from all the frost or champagne highlighters you see. I would not call this a natural highlighter at all, especially in natural light, but it IS beautiful! I like wearing it with an otherwise no-makeup look because it's so unique. It makes your skin glow, but with a natural face it sort of just looks other-wordly and like you can't quite put your finger on what is making the skin glow quite that way.
It's a powder product, but the texture is creamy/buttery. Goes on very smooth, does not accentuate the flaws in my skin, and blends very nicely.
I just wish these came in additional unusual colors. Can we get blue, red, and green highlighters please!
I'll be purchasing Fireball as well. :)
