This is a multi purpose liquid shimmer, although I don't see how it can be used on larger areas like cheek bones since it has a fine applicator tip and the product dries fairly quickly.
I use this as a cupidon highlighter (as an alternative to pearlised flesh tones) and an under eye brightener or eye liner. The shimmer is definitely more obvious than something like Guerlain #0 but would suit warm skin tones better.
This is a liquid golden highlighting fluid. I love to use this on my cheekbones for a nice golden sunkissed look. I find the KA shimmers very long-lasting as well. Gives a nice glow, not overdone shimmer at all.
