As the product just lasts 6 months, it's obviously very expensive! But the pencil is quite good,makes thin line, very easy to use, i really like it. the texture is a little bit thin because the ink dries too fast and it makes my eyes turned red!!! I don't know why, but this is the first time I've got this trouble with eyeliner. So stop Guerlain eyeliner, even though the bottle makes me feel sth lux... but no,never again

Everything about this liquid liner is fantastic. The brush is not too flimsy or too stiff, the formula is opaque but not overly so. I found that the liner was easy to apply as compared to other brush-tipped liners that I have tried. The brush allows me to have control over the product and gives me a defined line (wipe the excess off on the brush before applying). The pigmentation was great - not overly dark but not too light. It lasted all day!

This is absolutely top-notch. I purchased this in the brown color---and it is beautiful. I painted a stroke on my hand, and it goes on this pretty chocolate color (think Hershey's milk chocolate) but it dries darker (think Hershey's Special Dark). The packaging is at once beautiful and functional. I did a comparison with the new Maybelline automatic pencil which claims to give the same effect as liquid. I put the Maybelline on my top lash line..........and the Divinora on my bottom lashes. Well before midday I could tell that my top line was gone...........but the bottom line was still going strong! The tip on this is so fine that it's very easy to control and put on a clean, fine line. The result is beautiful. It wears beautifully and removes without a tug of war. I am finding that pencil liners just do not give me the richness & definition that gels and liquids provide. I would definitely repurchase this---and I think that it is definitely worth checking out. I was soo excited about getting this eyeliner, i've tried gel pots (Bobbi Brown) and a eyeliner pen (maybelline eyeliner express) and neither of them give the precision of an ultra clean, sharp and fine line or the high pigmentation and intense inky blackness of this Guerlain eyeliner (in Noir Ebene 01). This is a superior eyeliner for a very sophicated and well groomed look. The exact sorta liner you'd wear in the office, to an interview or when you know someone is going to be scrutinizing your eye makeup close-up. The nib on this applicator is soo tiny, and i find it easy enough to apply a satisfactory tiny, clean and sharp line just above my upper eyelid lash line. And as another reviewer mentioned, this goes on great as a finishing touch on top of Bobbi Bown gel liners. This eyeliner lasts just as well as any decent liner and yet its also extremely easy to take off with makeup remover. And I haven't noticed any eye/skin irritation. I haven't tried the lancome artliner that a few reviewers have compared this to, but then i have tried a couple of lacome products in the past that were a complete miss for me, so kinda been put off the brand. This is the first Guerlain product i've ever bought and I couldn't be happier with it! And I don't consider this that expensive considering the results it gives and the fact you don't need to buy an additional brush just to be able to apply it. Shu Uemura liquid eyeliner pen was my go-to liquid liner until recently - it was pigment and very long-lasting, easy to use. But the brush tends to dry up and the ink clogs if you don't use it regularly, and I found myself shopping around for an alternative. The Guerlain liquid eyeliner comes in a heavy glass bottle (feels like a cool pebble in your hand - very luxurious) with a long-handled fine-tipped brush. The formula of 01 (Noir Ebene) is a gorgeous, opaque, inky black. I've had no problems with flaking, even after 10+ hours wear, when I use it over primer and eyeshadow. You can get an extremely fine line with the brush, although for a thicker line it takes a bit of work. The formula doesn't dry very quickly though, and with my epithanic folds, I have to make sure the liquid is mostly dry before I open my eye otherwise it will transfer onto the lid. I find it works best if I start drawing with the brush at the centre of the eyelid, so it doesn't deposit the bulk of the liquid in the inner corner, where you want the line to be thinnest. Overall, I'm very happy with the product. I'm in love with this! The tip of this liquid liner is thin, and soft at the very tip. However, it's still firm enough to get easy control. It's also very easy to control how much product you are using since you just dip the wand into the little bottle. This thing dries fast too. I can apply layers of this before or after its dry and it would not flake one bit. This is the best liner ever, stays all day long, does not irritate my eyes at all and has deep colours (I have the black and the blue one). The brush is super fine and is easy to handle, and the little bottle is beautiful. Although it is pricey, I would buy it again for sure.

Smooth, opaque and deep matte tone. It's a challenge to use, like all liquids. It lasts longer than pens--a lot longer. The price is on the high side, but thats relative I guess.

I bought this and when I used it, it dried out to a line that actually broke! So I looked like a fool. I returned it and they replaced it with a new one. Presumably the other one was expired but the new one did the same thing. Terrible!
