I heard about this from Lisa Eldridge, since I have dark brown eyes and soft black eyebrows and lashes, I thought a 'softer' eyeliner would be nice. My skin tone is around nc20 in Mac.
I tried brown eyeliners before and against dark brown/ soft black, most brown eyeliners simply look weird/ sickly.
I ordered BB Sepia Ink looking at online pictures and reviews. When I opened the box I thought it's too light a brown and when I scratched the surface with my Mac eyeliner brush, the colour payoff was very faint. I think it was the surface as I dug into it a bit further quite a dark brown eyeliner came out. I would say colour is very close to Mac's Brun eye shadow. A black/brown. This eyeliner works even to fill in my eyebrows. It's matte and I find you need to layer a few times to get good definition and since the texture is drier than liquid eyeliners, it might be slightly difficult to get very sharp flicks. I also found it doesn't budge so easily. My eyelids are not oily but not dry either. So this holds pretty much all day.

Have been using this for about 2 weeks now and I absolutely love it. The colour is perfect for everyday wear. Easy to apply too and dries very quickly and it doesn't budge after that! I use the Ecotools eye liner brush with this as I find the Bobbi Brown mini eye liner brush (comes with the set - Black Ink, Sepia Ink and the brush - at Heathrow airport for GBP29) a little too small for easy application. A little goes a long way and I don't see myself finishing this product anytime soon! I do worry that it will dry out before I finish it though.

This gel liner has a dry consistency that I hate. Will not repurchase.

Lovely creamy formula but does not last on my oily lids, as it fades and smudges all over the place. Even using some powder and a primer did not stop the smudging, which was horrible. If you're a hooded monolid, this may not work for you. Also, the liner seems to dry up quickly if you do not tightly close the cap.

In terms of the sepia ink color, I absolutely loved it. It's a great light brown... not very warm, though. It's a tiny bit cool in my opinion, and perfect for everyday wear when you don't want something too intense like black.

This is the first gel liner I've tried and I've been using it for a couple of years now. I love it and won't be switching brands anytime soon! It's long wearing and I love that this particular shade (Sepia Ink) is not too harsh looking. I was worried about having trouble applying it at first, but it's actually very easy to apply! I've been using the same pot for the last 2+ years - a little goes a long way with this gel eyeliner - and it's only now that it's starting to run out. I'll definitely repurchase.

In the pot, Sepia Ink looks like it might be too light for my coloring (NC25, black hair and eyes), but it's actually perfect for an everyday liner. The color is a very dark neutral brown without any red tones. It's perfect for everyday lining and it looks great with my coloring. It's the tiniest bit lighter than Espresso Ink, but not different enough that you need both. I have noticed that it fades and smudges a bit at the end of the day, but it still looks good. My pot of Sepia Ink is creamy and smooth so I think it just depends on if you get a fresh pot or an older pot.

I love the actual product. It stays on throughout the day and it is matt which I like. The one thing I am not keen on is the brush. Overall a good quality eyeliner.

This is a very good eyeliner... A gel that can be applied easy. x

This was the first gel eyeliner I've tried. As such, I can't really compare it to other gel-liner brands. I thought and was expecting it would be creamier, and glide onto the eye like some reviews had suggested. The first time you "dig into it", it does go on creamy. But in my experience, if you try to take some product out of the place you've previously taken it, the application will not be as smooth and creamy. I've overcome this by scooping up more product and really pressing my eye-liner pencil deeper into the jar.

Pros: it is long-lasting.
Con: by the end of the day, the intensity of the look (ie if you had gone for a darker look achieved by not smudging the liner) had worn off and was not as intense.

Verdict: I prefer liquid liners.

I first bought this when BB were the only gel liners on the market, or at least the most popular ones. Back then I haven't heard of others, it was around 9-10 years ago. Point is, since then many brands came out with gel liners, I tried some (remember MAC in particular, smudged and faded really fast on me), and haven't found anything I liked as much this. Quality is great, easy to apply, really is long lasting, doesn't smudge or fade throughout the day, and Sepia is the perfect color for me, I don't like black liners, too harsh for my light coloring, and don't like many brown shades because they are too warm and make whites of my eyes look yellowish. Sepia is dark enough to be a good substitute for black, and doesn't look brown or warm. Versatile, goes with all the shades of eye shadow that black would. Great basic color. For tightlining with it I use Laura Mercier Push Brush, and for lining on top of the lid MAC #209 or Paula Dorf angled.

Pot lasts forever (very pigmented, little needed) and doesn't dry out (not in my experience anyway; I never leave the lid off, close it very tightly, and keep this, along with all my other cream make up products in the fridge). I repurchased it only once so far (but to be fair I haven't used this every single day, more like 3-4 days a week, and some weeks not at all).
