This concealer is a staple in my makeup bag! I love it. I've been using it everyday for about 2 months. The tube is very easy to use and sanitary i like that its not in a pot/jar. i use a moisturizer that's non-greasy as to not contribute to oiliness. I squeeze a very small amount on my middle or ring finger and pat it onto my under eye area and any blemishes or acne marks/scars (i cant help but pick at my face sometimes!). I don't use this on dark under eye circles so i can't comment on that but i still like to apply a bit of concealer to the under eye area, also i dont have wrinkles sooo..... I apply some to the sides of my nose and around the mouth to cancel any redness and it really covers my redness completely!! Nothing compares to this concealer it doesn't slide off my face or make my skin feel greasy at all, it stays put and coverage is buildable. My skin is light-medium. It matches my skin absolutely perfect, (its important to try makeup on in natural lighting** :) i have light skin with yellow undertones and some redness around my nose and chin. Also oiliness throughout the day i just blot it off with oil blotting sheets and my makeup looks fresh still. my powder foundation has more of a tendency to dissolve away as my face gets oily but my concealer stays put, thats why i love having this around and i use it everyday!! it hasn't clogged my pores, caused me any blackheads or broken me out. :)

UPDATE 4/26/12: This is HG. its been about 4 0r 5 months now i cant remember exactly when i started using it.. But its amaaazing, its smooth on my skin matches perfectly covers acne scarring and just looks like my natural skin and at the same time its very opaque. still has not caused me any breakouts or blackheads/clogged pores. And the best part is that it STAYS on all day.

Not for fair complexions - their lightest shade is really a medium tone. I have porcelain pink skin and their #1 concealer shade was really yellow. You don't hear a lot about it but us really fair girls have a hard time finding concealer and foundation light enough to match our skin tone. In most makeup lines the "fair" shade is always too dark. Why is that?
Even MAC doesn't have a NC5 concealer.

I love this concealer. It comes in a variety of shades, can be built to full coverage, and never looks oily or cakey on me. I think you get a fair amount of product for the price, and I love the simple squeeze- tube packaging. It allows me to get every little bit out with very little waste (looking at you, brush/ pen applicators!).

I really love this concealer! I use it for covering my dark spots caused by acne and my spots are extremely dark. Believe me! It covers up nicely. It does last nicely, but can crease a bit. I'm not sure about dark circles since I do not have them.

Covers up my bright red acne much better than what I used before - Maybeline Pure Cover Mineral Concealer, which I found actually highlighting my acne. The colour also matches perfectly~

Give it a 4/5 because it does look a little flaky when over-applying. You'd say "then don't put on that much", but than there is still some redness. I don't blame this on the product though; it's probably my technique that is lacking. (BTW, I set the concealer with Bourjous Bio detox perfecting powder)

This product works extremely well. I was tired of piling on layers of foundation in order to hide blemishes and discoloration so I went to Sephora and a very helpful sales associate matched me with Vanilla (I've never used a concealer before and was just using Estee Lauder's double wear foundation in Sand before this). It covers extremely well! The product is pretty thick so a little goes a long way, and it dries with a matte finish. I use a foundation brush to pat this on my problem areas and finish it off with bare minerals matte foundation. I wouldn't recommend using this for under eye circles, since it will end up looking pretty dry and cakey... but for dark spots and discoloration, this works perfectly! Expensive, but worth it.

I like this conceler but it is NOT FULL COVERege at all! i use it for my dark circle and it works well, but i have to add that i don't suffer from extreme dark circles...
it AMAIZING AS A EYE PRIMER. It brights up the colours so much an it holds in place because it is dry: give it a try if you have 30 euros spare!

I love this! I guessed and ordered the color Sand #7. It suits my NW30-35 skintone perfectly. This is the best for hiding melasma and blemishes, however I tried this under my eyes numerous times and it made the skin look super dry and crepey, It lasts all day on me (my skin is normal, with more dryness in the wintertime). It IS expensive at $30 for a half an ounce, but it is extremely pigmented and you only need a little bit at a time. If you apply too much it can look cakey but it is easy to use, easy to blend and once you get the hang of it it can make your imperfections invisible. Occasionally I just dot this wherever I need it, let it settle and then apply a dusting of MAC MFSN and that's all. I will buy this again!

I love this concealer! I don't think words can quite possibly describe how much this has helped cover my under-eye circles and blemishes. Like other reviewers have said this tube lasts for years even with daily use (which is awesome considering the steep price tag!) I am quite pale and find that the number 2 shade fits my skin tone pretty well. Although it can show up a bit light especially on top of pimples so I always make sure to apply a little foundation or powder over it. Once I finally run out of my current tube I cannot imagine trying out any other brand!

Honestly, I can't feel the hype on this product.
It performs decently but as much as I love MUFE I am not so into this product.
My skin is super fair and fine so I have little purple veins showing through. Unless I apply half the tube of this, they will still be visible after I apply it.
It can get a little cakey and flashes back like mad in pictures (it's always nice being taken a pic and finding out there's this little bright shinny gostly white spot on your chin like saying 'hi there, your blemish salutes!!!'

To conceal spots a tiny winy little goes a long way, I've had mine for like.. 3 years and it's still alive and kicking, as perfect as the day I bought it.

I like it for when I don't need a lot of coverage but when I need a REAL 'full coverage' this isn't enough.
