This concealer has worked well on me so far. I have deepset eyes and have dark circles that is brownish purple in color. Really bad. And I have this in NC30 and NC20. My shade with the foundations is NC25. It's just weird that this concealer doesn't have it in that shade? Anyway, I apply Bobbi Brown Corrector in Peach first and pat this in top and it totally covers and brightens my undereyes. My dark circles are my biggest insecurity on my face so I have really tried A LOT of concealers from drugstore to high end... Have a whole drawer of them but I grab for this one with the Bb corrector the most. I use the nc30 for a more natural look and the nc20 for a more made up look. Lasts on me very well cause I used it while I was in labor for 28Hours! Still wanted to look decent amidst the torture. ;)

I received this product in a swap on this website and had high hopes for it as I mostly buy drugstore products and thought a MAC concealer would be superior. However, I was disappointed at the consistency of this product because it is very thick and difficult to work with. It is fantastic for covering spots but as an under eye concealer this stuff creases and looks very drying. I much prefer NYX Concealer in a Jar which is a fraction of the price.

I have this foundation in NC15, which is perfect for my snow white-like skin. Mac foundations in NC15 are about four shades too dark for me (My foundation match is 'Siberia' from NARS) and I find this to be the perfect colour for me. It is incredibly thick but smooths over skin incredibly well and effortlessly, blends well and lasts all day, the only downside of this concealer is - it creases pretty badly. It is still a lot better than most drug store brands, and I wouldn't say I had particularly noticeable under eye lines - It just creases most of the time and has the tendency to look very very flaky and dry if under eyes are thoroughly moisturised and the slightest amount off too much powder is applied over the top to set. It contains a high SPF of 33 to 35 (35 in America - 33 in Australia) and the amount of product lasts AGES. Overall, I would recommend this product for very dark circles or over the top of spots/discolouration, but beware to use sparingly - blend well, and set lightly. Retails for around $18 in USA, $33 Australia.

Another fantastic product by MAC.

Pros:
- Conceals any blemishes, dark circles, scars quite easily.
- Great amount of product, I've had mine for months and I haven't hit pan yet.
- Awesome color selection.

Cons:
- Dry texture, unpleasant as an under-eye circles concealer.
- Expensive.
- You may need to reapply it during the day.

Overall I believe I'll purchase this concealer again, but I don't think it's the best out there. I'd recommend it for covering blemishes and pigmentation, and not to use it on the under-eye area. I hope I find a better more affordable concealer soon.

The MAC Studio Finish Concealer is a highly-pigmented option for those with severe dark circles or acne spots. When used correctly (following moisturizer and foundation) and applied lightly and gently to the undereye area, this concealer has great staying power. The MUA at MAC recommended applying this with a brush of medium to light density, and any of the white natural fiber MAC blending brushes would work- she used the 239 eyeshadow MAC brush, which works surprisingly well for acne spots. I personally prefer the 217 blending brush for the delicate undereye area to create an airbrushed, light coverage.

I don't know if I'm not using this correctly or what, but this just doesn't seem to work for me. It is a b**** to blend. I feel like when I put it over a blemish, when I blend it, it will just not cover it at all... this could be because my house is very cold and this concealer is very thick and it's just not blending properly, but I havent had the best luck with it. I think I need something more liquidy.

I'm in love with this concealer. It has a great coverage that lasts for hours. It is ultra creamy so you only need a small amount. It is buildable and it covers scars and blemishes pretty well. The only downside is that it creases on the eyes' circles sometimes, so you have to warm it a bit first and blend it well to prevent that from happening (and use some moisturizer first on the eye area). Overall, one of my favorite concealers!

This is the concealer that I've been using for a while and I'm not very satisfied with it, but I continue to use it since it's the only concealer that give my very bad dark circles a little coverage. I use the NW40 and use the NC45 foundation. This concealer creases like crazy and it goes into the lines under my eye. It's to orange for me, but the NC concealer seems to get really grey, so that's why I use the NW one.
People recommend the Bobbi Brown concealer, but I'm not sure if I have to buy one. Because all the MUA/SA seems to giving me the wrong tone and I spend so much money on concealers.

I LOVE this concealer! It has replaced my all time favorite, benefit erase paste, and it is much cheaper. Heed the warnings about using it as an under the eye concealer-it does crease. I apply mine with a light hand and blend it very well. Dust a bit of powder over it.
It is a very creamy, long wearing formula and a little goes a long way. I use it in shade NW20 and it matches perfectly. I don't have acne so I can't say how it works for covering that, but I do have a lot of chin/nose redness and it works beautifully on this area. Give it try!

PLEASE take all the comments about this concealer performing poorly as an under-eye concealer seriously.

I bought my own Studio Finish concealer in mid November 2012. The MUA I had was great- she expertly applied SF concealer in NW45 to cover the hyperpigmentation around my mouth and left side of my forehead, applied Studio Sculpt liquid foundation in NC45, and finished it off with Mineralize Skinfinish Foundation in Dark and some Studio Fix Plus spray. The thing is, she seemed to sort of ignore my request for her to put some SF concealer under my eyes (she dabbed a tiny bit there)- I wondered what that was all about. When I went on vacation to my parents' home country (tropical all-year climate), I wore the concealer with no issues- albeit my dark spots could not be concealed as well as I liked...

I returned home and wore this out for the first time since my vacation yesterday. Came home, and lo and behold, hello Creaseland under my eyes! It was so cakey- the product had totally settled into my under-eye creases, making me finally look like every one of my 27 years! :S I know NW is supposed to have peachy tones, but I'm not sure this is working well to cover my hyperpigmentation.

For reference, I apply the product to the above areas with the L'oreal concealer brush, which I love. I try not to apply too much, but this is difficult when I keep feeling that the dark areas are still too dark. For about 6-7 hours, though, the concealer does do its job well and does not cake up or 'move' around my face ( I use primer, moisturiser, and a Japanese finishing spray).

I will keep using it until it runs out, since I paid AUS $36 for it, but won't repurchase. Time to stalk the Bobbi Brown booth again...

UPDATE: 17/01/2013: I finally got a Bobbi Brown Creamy Concealer in Almond and oh-em-gee!!! Excuse the annoying exclamation marks, but this concealer does so much better at covering my hyperpgimentation, including under the eyes! I also bought a Laura Mercier Secret Brightening Powder in shade 02 and dabbed some on top of the concealer, and my goodness! I don't look old like I did with the MAC SF concealer! There's no creasing either- just a very nice, velvetty matte look. Try this combo, ladies! :D Now, if only there was a worthwhile way to get rid of all those expensive but useless MAC products I bought like an idiot... :S
