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 severe dark circles and have tried many products, this is the best one for me. It has great coverage and texture, and applies easily. I also use it for spot coverage on other parts of my face.

Tip. For sever dark circles I use “Benefit Lemonade” under “Benefit Boing” as it neutralizes the dark tone and gives a fresh, woken up look.

i don't find that this conealer is anything special. it is matte and heavy duty, good for concealing blemishes if you can find a shade to match your skin tone. it does a fine job at correcting and concealing under the eyes, very blendable too, but i do find that it can cake up over time and it really settles into fine lines. not worth the $, especially considering sonia kashuk makes a concealer palette for half the price that follows the same idea, only it does a waaaaaay better job.

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 the first high end concealer I have tried, and so far I'm not a fan. The creamy consistency of the product appeals to me, but that's about the only thing going for it.
It hardly coverd up anything, and it emphasized every last flake of dry skin I put it over. Mind you I do have fairly dry skin in the winter, so I might recomend this to someone with oily skin since it did stay in place all day, but it's definaty not a product for the dry skin folks. There is a colour range of 3 (light, medium, dark) and if your not one of them, it's virtually impossible to blend out (at least on dry skin).

So overall, love the feel, hate the rest.

This is the only product that erases my matching luggage underneith my eyeballs.

Definitely a product to have in your make up back if your undereye Vuitton is dark and not so attractive.

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 :)

I really really like this concealer! It's not too expensive and it lasts forever which is a great bonus! I bought this in the lightest colour available, since I am very fair. I use it to cover up redness, under-eye circles, and to cover discolouration on my eyelids. It's really easy to use, doesn't streak and leaves my skin with a flawless look. I warm it up between my fingers before I apply it so that it just melts onto my face. It's a great product! very versatile, and I will repurchase. I've had my current pot for about 2 years now, and I still have many more uses ahead of me (just to give you an idea of how long it really lasts)

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...
