I have a problem with dark under eye circles and have not found many products that can conceal this without making the area look worse by creasing, looking dry or looking cakey.
This is one of the better products I have found.
First off the applicator (shown in the picture) is extremely hard to use (my foam part actually pops off all the time which is annoying and not to mention messy) and surely is a breeding ground for bacteria. Anyway, I have the older packaging also, which is just a plain squeeze-able tube which i much prefer.
The product itself gives fantastic coverage and nearly fully conceals my darkness (yay!) but it still can look a bit dry sometimes. It doesn't seem to settle into fine lines as noticeably as some other products and stays in place all day long. I find it blends easily with my foundation and is easiest to apply with fingers or the tip of my miracle complexion sponge (I don't find a brush works well at all).
I would definitely recommend this to others with dark under eye circles that need covering as it does a nice job and is much more affordable than other high end concealers that I have heard this compared to. I will definitely repurchase in the future.
I really don't understand the hype around this concealer. I found it creased on me, wasn't easy to blend and even seemed a little drying. I don't usually have a problem with creasing so I just couldn't get on with this product! Maybe I had a dud?? The coverage was ok, but didn't really redeem it. The packaging isn't the best just because I don't like the sponge applicator, would much rather have a pump. Not a lot more to say about it, may be great for someone else as a lot do like this, but I was disappointed.
