My ONLY complaint about this product is that it is LE !!!

other than that I am in love and lust with this little pot. It has helped me shape and give color to my mini brows (nature did not bless me with a full set of eyebrows). I have the Dirty blonde shade and it is perfect. It is a far superior product to the MUFE simply because MUFE has not bothered to perfect a more user friendly packaging.
I apply the Fluidline Brow gel with a thin eyeliner brush and just draw on small eyebrow like hairs and blend them in with my own measly hairs.. and it works!.. I hope MAC brings these back as perm products and I will stock up just in case.
This product is a lifesaver for all the eyebrow challenged.

I love it!! I was using my clinique gel liner in deep brown for my brows but this stuff is so amazinga nd I'm glad they made it. I'm just upset that it's L.E. Hopefully they make it a permanent item. thats the only reason I didn't give it 5 lippies

This did not work out for me. I have really sparse brows to none so there's nothing there for the product to hang on to but my skin (really) so it looks streaky and uneven.

This is a no from me.

I like the texture, and I like how long a pot will last (you only need a tiny bit). I like that it seemed to not only colour, but thicken my sparse brows. But there are issues.

1. The "Deep Dark Brunette" isn't all that deep and dark, and worse - it's got orange undertones. I looked like a freak in daylight when I had this on. They really need to make a shade that's more ashy. Too much orange in a very common mistake in brow products (some Anastasia products come to mind). I'm surprised at MAC, since they are all about colour, and their brow pencils (Stud, etc) are very good, shade-wise.

2. I have oily skin and most brow products, after some time, start to look patchy on me (and I wipe with alcohol before I apply so there is NO oil to start with).
This lasted about 6 hours - not too bad, but not great either.

I had better luck with the MUFA brow gel. Overall though, still prefer Suqqu brow pen (great but hard to get) or Stila All Day Waterproof Brow Colour (easier to find and it's got the right, ashier, tone for me), with a bit of Illamasqua Brow Cake in Gaze over top.

For the love of God I can't understand why MAC has launched this as a LE item- it is AMAZING. I had been using dark brown powder to fill in some thin brow areas for years and never realized how much better they could look with the right product. This is a game changer. Seriously. I can't speak for the lighter colors but I use the darkest one and it matches and blends into my dark brown brows perfectly. I will stock pile this as soon as my local stores inventory is replenished. They only had one light color left as of tonight.

I've been using a Vincent Longo eye detailer brush for this which has short, square firm bristles. There are many brushes you could use for this. Once applied, it stays all day and night without any fading or smudging. It's an absolute must for anyone who needs a little help perfecting their brows. The texture is slightly drier than the fluidline liner and goes on ultra smoothly with just a tiny amount of product on the brush. I can't recommend this highly enough!!

I love this product! I've got several strikes against me in the brow department: They are fair - almost clear, somewhat sparse, a few bald patches, and thin, and I'm a natural redhead. I've drawn on my brows daily for several decades, generally using some sort of warm toned light to medium brow pencil, or a lip liner in a warm tone, topped with a trio of eyeshadow colors to add depth and help cover both the skin AND the hairs. It was a major production, and never lasted all day long without smudging. I find the FluidLine Gelcreme sticks tight, tints both hair and skin, and the colors Redhead and Dirty Blonde are both suitable on their own for me - the Redhead provides a bit softer of a look, as it reads a little lighter, and Dirty Blonde has a great neutral tone, not ashy, and works well on its own for a more structured look. Some days I even layer them, applying Redhead first to add that warm copper undertone and then putting Dirty Blonde on top to strengthen the line. One product, goes on easily and fast, is somewhat blendable so I can perfect the line. I am in love.

I love this stuff. It's genius really. Very similar to the MAC Fluidline Eyeliner. It's thick, but not too thick, goes on very easily, and lasts ALL day. It is waterproof, so you don't have to worry about any smudges or anything like that. I have dark, thicker brows, that I get threaded, but I still like to fill them in for a more defined look. I use a simple MAC angle brush for the application. It took Me about 10 mins for both eyebrows. I went with the Deep Dark Brunette color. It's also available in a Blonde, and Red Head color I believe. For only $15 this stuff is golden. ;-D Go and grab one!

Genius product! I heavily fill in my brows every single day, and I am always on the hunt for an HG brow product. It must match the color of my brows, be easy to apply, and last all day (half a rubbed off eyebrow is not a good look) this product fits all of the requirements, plus some. I absolutely love the color for my dark, almost black, eyebrows. I have the shade Deep Dark Brunette, and it's perfect. Typically dark browns will contain hints of red, which looks ridiculous on me, but this does not. It's also super easy to apply with a standard angled brush, and it lasts allllllll day. Even in the Las Vegas heat. It reminds me a lot of the Makeup Forever Aqua brow, except I prefer this to that for two reasons, it's cheaper, and the packaging is better. This product comes in a typical fluidline container that can be easily closed. It's also a hard wax, so you can't spill any of it, and you do not run the risk of squirting out too much like you do with the Makeup Forever Aqua Brow. Definitely recommend it! It came out in a brow specific collection at MAC yesterday. Not sure if it's limited edition or not, but I'm going to pick up an extra today!
