I swatched a demo product (in a shade too dark for me) but...man, oh, man. It was smoooth, metallic, NOT-GLITTERY, and blended out sweeet.
So, I bought Afterglow (and would also buy Summer Glow if it was available in Canada...cry). This is a pale, beige that leans cool. I've had a difficult time with most popular highlighters being too dark for me (around NC17-20, neutral-cool yellow-olive), but this is light enough and lovely. (Darker shades available if you need them!)
So, this is one of the few highlighters I've truly loved. Very versatile - inner eye highlight, brow bone, cupids bow, cheeks, you name it.
You can use lightly but it builds up FAST into a very noticeable glow.
If you appreciate glow without sparkle, give this a try. It cost me $16 CAD at SDM, a bit pricey for drugstore but a quality product.
