Here is my new favorite under eye concealer...
LOVE LOVE LOVE this!!! It is inexpensive (I got it with a coupon and paid $6- normally 9), it covers the darkness with a little bit of product and it does not settle in the fine lines. I dust over it with a little HD translucent powder and it stays all day.
The color is also great. I am super fair and have a hard time finding concealers that don't appear a little orange on my skin- i am using this in Fair, but they also have shades in light, medium, honey, neutralizer and brightener. The neutralizer shade is for extreme dark circles and the brightener is more light reflective. The applicator tip is anti-microbial- I break out very easily, but haven't had a problem with this causing any breakouts. If you're nervous about using the same applicator on your face every day, you can always dot it on the back of your hand and apply it with your fingers, a brush or a sponge.
As far as my own application for this, I give it a couple of clicks, dot it under my eyes and use my ring finger to pat it into my skin. It doesn't need a ton of blending, just patting and it really doesn't look cakey at all.
I can't say enough great things about this product! For all you frazzled moms out there like me who have been shopping until the wee hours of the morning only to wake up the next day with more to do... try it out! It would also be a great stocking stuffer for those ladies in your life! Merry Christmas!!
