I'm on my third container of this, not because I used up the other two but because they reached their expiration date.  This concealer does a really good job of cancelling out blue/purple tones under the eyes.  It doesn't have much of a brightening effect, but it's the only concealer I have tried that I can use on its own without being patchy or creasing too much.  It also allows me to use other more brightening or higher coverage concealers which would otherwise be too dry or crease a lot.
