I have these shimmer strips in shade "Natural Nude". What a gorgeous product. On the back of the packaging, it says it can be used as an eye shadow, blush, highlighter, contour, and bronzer... I dare to disagree about the blush and contour part, it is way too shimmery for that in my opinion. It does not work as a bronzer on my face either. But I quite enjoy it as an eye shadow and, most importantly, a beautiful highlighter. It's pigmented, it's glowy (but not glittery), it blends nicely and has a good staying power. Easy to customize your own shade by mixing different strips.
I have purchased this highlighter more than two years ago and have been using it almost daily. And I'm only about half way through it! I really hope Physicians Formula won't discontinue it before I need to repurchase it :)
