So I FINALLY found this in Ivory!!! I was looking for it forever. I tried the Superstay foundation, did not like it as the colour match was terrible for me, but this concealer is awesome. I think for an undereye concealer, this is the best one you can find in drugstores. It covers very well, is super smooth and lasts. I bought this for around $8 CAD at Walmart.
Here is what the product claims to do:
* Conceals imperfections, flaws, undereye darkness and circles
* 24-hour wear, No Transfer
* Oil-Free, non-comedogenic, dermatologist tested, ophthalmologist tested, fragrance-free. (taken from Maybelline website)
It comes with a doefoot applicator, as most liquid concealers, you dot it under your eyes and then lightly blend it in. The colour match of "Ivory" works well for my light skin. I wish their foundation was more this tone, instead of the reddy mess that it was on me. The consistency of this is liquid, but it's a thick kind of liquid, so it does a very good job in covering areas quickly and a small amount goes a long way with this.
I've read reviews on makeupalley that list a con of this product as it drying too quickly, I don't see that as a problem at all, I like that it dries fast and to a sort of powdery finish. Especially for the summer, hot months, you want something that takes as little effort as possible. Also, it only comes in 5 shades, which definitely may make it a problem to find your shade, I found mine with no problems though, Ivory is perfect for me.
