I like the Boi-ing concealer just make sure that the colour will match your skin tone. The undertones of this product don't always work with all skin tones.

I find this concealer really nice. it's easily blendable and provides pretty flawless coverage! I find it just slightly overpriced, but it's definitely worth it if you use it sparingly.

I first tried this concealer a few years ago after running out of my previous concealer. I had wanted to try something new and had heard a few things, good and bad, about this "industrial strength concealer", but finally decided to give it a try. The colour range isn't great, which was a concern for me since I am quite fair and the lightest shade of some brands are often still too dark. However, I did find a shade that matches me almost perfectly (shade 01) and it was around $20 at sephora. The product itself is, unlike its shade selection, fantastic! It covers redness, blemishes, freckles and even scars. It's texture is smooth and blends really easily into my skin. I didn't find it greasy at all and it didn't make me break out (although I have heard otherwise from other people). The coverage lasts all day and does not change colour, crease or melt off my face. It has since been a new favourite of mine, and my first choice of concealer. Overall, this concealer does everything it is said to do and althought its a tad pricey and has a sparse variety of shades, it is worth it (One 3.0 g concealer usually lasts me anywhere from 4-6 months). Boi-ing concealer is one of those products I will always keep on hand.

I have such a hard time finding a concealer that would cover my dark circles and so far the Benefit one is doing the best job. It doesn't cover all my dark circles, I feel like I still notice them a little bit.
It has a nice texture but I would recommend using an eye cream prior to application to reduce friction when blending with your fingers. I find the best way to apply is dab a bit of the product under the eyes and blend with a foundation brush or a pointed foundation brush.

I've tried a LOT of concealers in my almost 30 years of dealing with bad dark circles and I have finally found the right one for me. I love the texture, it just fits well on my skin, matches my skin colour, and does the job for longer then anything else I've tried. That being said, I do have to be careful before I leave in the morning, sometimes I don't rub it enough and it's a bit visible. I feel like it's more my fault for badly applying it then the product's though.
The price is not cheap, but it lasts for a very long time so it seems worth it. I used Mac concealers a lot too, but I just like this one best.

This is a great concealer, I have HORRIBLE dark circles. I had been using Glamaflauge from Hard Candy for awhile, but I bought this two weeks ago, and have used it every day since. Concealer is a must for me, and this works great. I put one layer under my eyes by swiping my finger underneath and then a second layer while dabbing lightly with my ring finger. I set it with finishing powder, and it works great! It's $19, but worth every penny.
I love it, and will definitely re-purchase! :)

** In the picture, My left eye has concealer on and my right does not. It will be mirrored as you look at it. You will be able to tell though. I hope anyone who buys this loves it as much as I do :)

While I agree that this is pretty "cakey" concealer, I find that once blended, it's great and gives me the full coverage that I'm looking for. It takes away my "up all night" dark circles. I would be totally lost without this product. It's the one Benefit product that I keep coming back to...

I really really like this product. It's so effective and easy to use. Super easy to take off as well. When you have it on it appears quite natural looking. Definitely worth the money. I find that this type of concealer lasts a lot longer than the liquid ones.

Bo-oing is incredible! I tried it once in Sephora and was impressed at how seamlessly it covered a particularly nasty blemish. It completely covered the redness and did not crease or move afterwards. I believe it comes in three tones – light, medium and dark. The medium tone comes in the Realness of Concealness kit. There is nothing bad I can say about this concealer – it really works like magic. It does the job and stays put. The name industrial is very well suited to this product.
