A great, very professional yet very easy to use product in a hygienic packaging. It is expensive but I don't think I'll ever run out since I use a tiny amount of product each time.

I have this in number 3, which is a dark brown. It is waterproof as it claims and it just lasts forever until I remove it.

I apply a little dot to the back of my hand, then using MAC's 208 brow brush I pick up a little product then keep swiping it on cleaner parts of my hand until it starts drawing a totally dry line. Then I take it to my brows and apply it in light strokes concentrating on sparser areas.
I finish up by brushing through my entire brow using a brow brush.

The key to getting fantastic results is to use a very very tiny amount, and a good brush ofcourse, or else you'll end up with a mess. It really is super easy to use.

Will repurchase when I run out, I would try a shade lighter though, cuz shade #03 can get too dark easily.

This stuff is pretty great but since it didnt live up to my expectations 100% i have to give it a 4.
although it i s tricky to apply, and tricky to get the perfect brow, once you've managed to get it, it's worth it. it's SUPER pigmented and yes... a little goes a very long way.
the only thing is, i REALLy expected it to be super waterproof, and well, it was kind of water proof, but definitely not what i hoped for.
i live in miami and sweat a lot through my face (so annoyign, btw, it's like a freakin curse), and when i passed my fingers through my brows to take off excess sweat i saw a bit of the brown on my fingers, not a lot, but still...i saw.
the shade 4 matches my brows perfectly though so that's great.

On my fair blonde brows, the color 0 is rather reddish, but i don't mind. I apply this with the "back on the hand" method using the stila eyebrow brush and layer MAC brow set over it. the texture is a bit watery and a little goes a LONG way. don't even bother buying the set with brushes, you only need the tube of color and your favorite angled brush. I can go all day without touching up my brows and it never looks like my eyebrows are sliding down my face ;) looks natural in all lights. i couldn't find it at my Sephora (not even a display for it) and had to order it online.

I was so excited to try this. I have seen Carmindy using this on What Not to Wear for years but I didn't fit into the either of the two colors. Good for all us dark-haired girls, they came out with 2 more shades. I have this in #4 (the darkest shade). It takes a little while to get the trick of it. The first time I used too much and looked like a cartoon character. I switched to a very tiny eyeliner brush and a very light hand with the product, and am much happier. The tube is $19 which might sound a bit pricy, but with everyday use I could see this lasting a whole year. I use this primarily to fill in the ends and sparse parts of my brows and I feel that it looks pretty natural. I was really drawn to the "waterproof" claim. I will have to do further testing on lasting power, but I trust the brand. So far, I love it!

Edit: To test it's waterproof claim I wore it to my hot yoga class. At 105 degrees for 90mins it held up ok. Melted off about half way but the fact that it was there at all afterward is a miracle!

This isn't foolproof but once I got the technique down, (the technique that worked for me personally) I fell in love. I have this in 03 which is a perfect neutral dark brown for my brown/black, sparse brows. A little goes a long long way with this and the tube should last forever...I always squirt out just a bit too much each time but I'm getting the hang of that too. My brows have bald patches and need filling as well as definition since they aren't dense to begin with. Needless to say I've tried millions of brow pencils, pens, powders, waxes, blah blah blah... (I'd say my brows are the trickiest part of my makeup routine)
This is my "go-to" product right now. I use an angle brush and dip it into a tiny dot of product I've placed on a paper towel. I then draw a line or two onto the paper towel before placing the brush where needed on my brow area. This gives me more of a smuded, soft line/dash/faux brow hair than if I were to apply the full strenth cream onto my skin/brow. Once I fill and define my brow I use a spoolie brush with slight pressure over the finished brow to blend everything out. I'm really pleased with the result this gives me. (My profile pics don't feature this product...the brows are especially awful in my headshot so not a good reference for this in case you look, lol)
EDIT: I'm changing my rating from a 5 to a 4. This takes a little bit too much work when I'm in a hurry and if done poorly can be too dark and fake looking. I recently plucked my brows to a thinner shape (I can't leave well enough alone) and the brow corrector doesn't look realistic in the bald patches. So better as a filler/darkener than a "No, I really do have hair here" fix.

It took me over a week to track down this product, but when I did it was worth all the work!

I had been looking for a liquid/cream brow corrector ever since Carmendee from What Not to Wear began recommending that type of product to all the show participants. This was the only non powder/wax combo available on Sephora.com other than the mascara tube/wand type products which I find terrible. Despite rave reviews on the site, Sephora.com was out of stock. In store- even less luck. The sales associate had never heard of the product and there was no empty spot on the display. I tried a large drugstore chain that sells the brand in Canada, no luck. Finally I was walking by SEARS of all places and noticed a MUFE display. Jackpot!

The make-up artist at the counter colour matched me. I am actually between two shades, but went with the lighter one. This product is highly pigmented and the tinniest drop is enough for both my brows. I use a Quo angle brush to apply the product in short strokes and it looks very natural. Since you are applying the product to the skin in the brow area, I find coverage is a lot better than can be achieved with products that are either darkening existing hairs or relying on a powder to do the same thing as the cream. Unlike powder/wax combo’s, this product looks great with a relatively nude face.

My only complaint about the product is that there are not enough colour options. Extremely light and dark haired people are completely out of luck. The price is also a little steep (about $27 Canadian), but considering the size of the tube and the amount needed, it will last me years!

Love IT!

Pros:
- I have it in nr 2. Perfect match for my eyebrows. You dont even notice it.
- Hygenic packaging. You even get two brushes. I love the brushes. They are short and easy to use.
- The product is highly pigmented. Little goes a long way!
- I only use it to draw the end of my brows. not to fill them in.
Its excellent for that. You get a perfect line!

Cons:
- It rubs off!! But its not a problem for me. I dont touche my face.

Price vs quality= Good.

This product stays on all day, even if you have oily skin or if you sweat. The color match was perfect for me too. I have dark brown hair with a reddish hue to it, and number 2 is the perfect eyebrow color. Apply it with a light hand so you don't look like Bert from Sesame Street, but that's the case with any eyebrow product.

Update: argh, this started breaking me out along my brow line! I'm not editing my review, because until it did that, I loved it. Crud. Now to find something new and better.

My absolute HG. I like perfectly symmetrical, strong, well shaped but natural looking brows. I use stencils to lightly outline my eyebrows with Kevyn Aucoin's fabulous Precision pencil in brunette. Then, I put a pinhead size of the corrector in #4 (#3 is good too but has more red) on the back of my hand and swirl the beveled brush that comes with the kit around in the gel. It's highly pigmented so a light hand is a must. Just apply lightly with the brow brush that comes with the kit, following the direction of the hairs. I let it dry for a moment, then powder and lightly brush my brows with a spoolie brush. Done! And, it lasts all day. The additional tiny, tapered brush that comes with the kit is great for drawing in individual hairs when you have the time. I haven't tried this product in summer yet, but if I find that it doesn't melt in hot weather I'll know I've found Brow Nirvana.

This made my eyebrows look too drawn-on. I have Asian eeybrows that aren't sparse; rather just average in thickness. I wanted it for its waterproof ability (to swim and still have my eyebrows on), but it doesn't last longer than the 3 Custom Color eyebrow powder I use. The color didn't quite match my hair. Powder just has a way more natural look than this liquid-to-powder formulation.

I liked the packaging though. The tube gave just the tiniest amt needed because a little really does go a long way. I really see this as a corrector for those who has relatively thick eyebrows: to fill in spots and polish up your already thick eyebrows.
