Once out of the box, this is what you get, a black squeeze tube, which is the undereye brightener and then the nub on the end is the concealer. The way the package functions is you take the plastic cap off the nub and then the nub off and you get the squeeze container of the eye brightener (applied first) and then the nub is your concealer. You can apply the concealer by taking the nub (awkward to hold) and applying it directly or taking some on your finger and applying it (I suggest this). However, you'd be best off to screw the silly nub back on the package and apply it. The packaging is really awkward and weird, and gets messy.
I like the concept, since we should all use a cream under our eye to moisturizer and prep the area before applying concealer. This makes it go on smoother and not sweep and crease into lines (if you can manage that). But this is just awkward to use in my opinion. I did not notice any brightening qualities to the cream though, no shimmers or glitters in it.
Here is a swatch of both ends, the eye brightener comes out white, but once blended in it's clear and quite thin and applies well I think, it's not bad at all. The concealer is quite drying and sticky and reminds me of the lipstick consistency that you'd find in many drugstore concealers. The concealer definitely needs the cream or else it will crease for sure and look very dry under the eyes. The coverage is average too.
Would I recommend this? No. It's just an average concealer. It only comes in three shades, which may be a problem for some. I have it in the lightest colour here, Light, which is yellow toned. I prefer the eye cream in this over the concealer itself, and you get a lot of it, so if you like it, that's good.
Have you tried the Hard Candy Undercover Agent?
