When I first got this, I was immediately put off by how shiny it was. You had to blend so much to make this wearable, you would end up blending your foundation right off.
However, I found a use for it. I recently purchased an airbrush machine for a huuuuge discount. I love the coverage and longevity of airbrush foundation, but the finish on them tends to be extremely matte. I tried so many things to make my foundation look more natural (seriously, the finish is unnaturally matte) from highlighters, to the special liquid that came with the machine, to luminating primers. Nothing really worked like I wanted it to.
I was re-organizing my stash one day and found this in the bottom of one of my junk drawers. I swatched it, reminding myself of how shiny is was. I figured if a luminizing primer was no help, this might be shiny enough to work.
I applied my primer like usual, then blended this onto the areas where you would normally put a highlighter. Waited for a minute or two for it to dry down a bit, then did my airbrush foundation over it.
It made a HUGE difference in the look of my foundation. My skin looked healthier and, more importantly, I got a more natural finish than I can remember getting with any other products. I have the lightest non-white colour (the name has since worn off the tube). I'm guessing a similar application trick would work with the other colours used as blush or bronzer.
So for those of you who can't get past the insane weird shiny finish that this product gives you when you use it on TOP of your makeup, try putting it under your foundation or powder. You might be surprised.
