I purchased a travel set of three Stila liquid luminizers, and they're really nice! They have a nice shimmer to them, rather than the glow that some people might look for in a luminizer.
It's very easy to apply and add to your make-up routine, since it's thin. Because it's liquid, it blends pretty well and doesn't leave any residue or cakiness. I would definitely recommend trying this product out in a smaller size first, to see which color complements you best, and if you like the shimmer!
