I got the mini sample size of the NARS Orgasm Illuminator free with another purchase at least six months ago, and the fact that I still haven't used up the teeny tube shows that this isn't a winning product for me. It's a golden sparkly thick liquid which can be used as a highlighter, or worn under, over, or mixed with foundation to supposedly give a luminous glow. Whilst the swatch photo shows that alone the product looks promising, worn over foundation the product seems to just disappear, not really leaving any effect at all. Applied as a primer layer, even a CC cream covers the little luminosity it creates. I've been slowly using my tube up by mixing with foundation, but you need to thin your foundation down with the product a LOT in order to see any glowing effect - not good if you like a high coverage. All in all a very disappointing product; I'm only glad I didn't spend good money on it!
