As far as sample sizes got I'm pretty happy with this one, though it is tiny you do actually get a lot of product in it. I quite like the applicator too, it's a little brush that you can just sweep over your face.
Now, I love the subtlety of this product. At first I wasn't sure how much to use, whether less is more, in almost all cases that's true. However when I first tried this on my face I used the smallest amount and couldn't really see a difference so when I added more I started to notice the highlight and really loved it. It's far less shimmery than my powder which works really nicely.
Recently I have found myself using this highlighter when I am going for a more natural look, so when I've only lightly contoured and no eye shadow, my most simplistic make up, this works really well. I think if I was to go for a more "fierce" look or just a full face of make up, this highlighter may not work as well as my powder.
I'm super impressed with this highlighter and can definitely see me buying the full sized product.
Have you tried Highbeam?
