I received a deluxe sample of this Hourglass Caution Extreme Lash Mascara as a free gift with purchase. I’ve been using it for a few weeks now and I gotta say, I’m disappointed. This product is a 100% vegan mascara that claims to deliver 400% more volume, dramatic length, and sky-high lift for extreme lashes. I give the brand props for the vegan formula, but claiming “extreme†anything is a very blatant lie… I don’t see any of Hourglass’s claims whatsoever. The formula of this mascara is smooth and buildable, except it doesn’t build enough despite coat after coat. It defines your lashes nicely, but it gives very little length and I don’t see any volume despite using every application technique in the book. Not to mention, the person who designed ... MoreI received a deluxe sample of this Hourglass Caution Extreme Lash Mascara as a free gift with purchase.

Not to mention, the person who designed the triangular tube should be fired, I can’t tell you how uncomfortable it is trying to get the tapered brush near the inner corner of my eye without the sharp edge of the handle poking the other side. Granted I imagine this is more of an issue with the deluxe sample sized tube than the full sized, but it’s still a major oversight in my opinion. I’ll give credit where credit is due, this mascara doesn’t smudge or flake throughout the day and the definition it gives my lashes is unmatched. But I would never buy a mascara just for definition, especially since I have naturally long lashes and I’m looking for something to give me some volume and fullness. Wouldn’t buy this in a full size.

This is currently my favorite mascara, but I would still say that I haven't found my PERFECT mascara. Which would be: basically this one, but without the occasional, random undereye smudging (because if that were happening every time, I'd have kept looking without hesitation, but because it only happens sometimes unpredictably I'm mostly happy but sporadically confused.)For anyone looking for tips in the reviews, this comes off easily with my Banila cleansing balm.I've liked getting the mini size because it seems like it dries out and runs out around the same time, which is ideal. But I feel like lately they've changed the length of the wand, because it's much harder recently to maneuver around the edges of my eyes. And honestly, if that continues to be the case ... MoreThis is currently my favorite mascara, but I would still say that I haven't found my PERFECT mascara.

I don't know if it's worth getting the full size but the wand needs to be functional.

I’ve tried dozens of mascaras, mostly high end, and this is the most beautiful. The way it coats your lashes without any clumping, and the colour and silky ‘texture’ of it just looks.. well, expensive. It doesn’t flake or smudge and lasts all day. It definitely lengthens but adds a lot of volume, which is what I want most. There are other mascaras that give more volume (like Too Faced) but they don’t last without smudging. This is the only mascara I have that looks wonderful even when I don’t use an eyelash curler first. It’s not easy to remove with an oil cleanser; I find it’s best to gently rub the eyelashes between wet fingers, the same way you’d remove a tubing mascara, and then it comes off easily with an oil cleanser. For this reason, I heavily doubt it’s ... MoreI’ve tried dozens of mascaras, mostly high end, and this is the most beautiful.

Trying new mascaras is something I take pleasure in, but after buying this mascara for the first time I may never try a new one again. My lashes are already pretty long so I can't speak to the lengthening effects of this mascara, but it does everything else I need. Volumizing but also separating lashes enough so they don't look clumpy. Provides adequate pigment with just one coat. It dries quicker than any other mascara I have tried - which I like because if the mascara stays wet on my lashes too long they will sometimes clump together. Because it dries so quickly I do feel like I need to repurchase sooner due to the tube drying out, but maybe just a few weeks sooner than I would ordinarily replace other mascaras so not a big deal. Over all 10/10 would recommend.
I just wanted to write a review for it because finding a mascara was a long journey for me. I have sparse, short and thin lashes, not a great base to start with. This mascara sticks to the lash and actually coats it and lenghtens it properly, keeping it curved without me having to use a lash curler. I have saved my lashes by being able to give up the curler. I use an occasional heated wand for more curve. The mascara is not waterproof (tested) but omg it doesn't smudge or melt at all. It stays put all day long. You need to apply all coats in one go, it's not possible to apply extra coat after first one dries. It is the most decent mascara I found so far. Ideal? no, but the best so far and I have tried half of Sephora mascaras so far.
This mascara is AMAZING! I don't normally write reviews, but I needed to talk about this!So the best part is it's longevity, to the point where if I forget to take my makeup off before I go to bed (terrible habit, I know) in the morning it is STILL on just as strong! Amazing!I'm also an actor and if I know I'm in a scene with lots of crying and lot's of re-shoots, I ALWAYS wear this mascara as it doesn't even run if I'm crying! So we can re-take and I don't have to re-do my makeup, I love it!It's never given me panda eyes, and stays on until I want it to come off.It's great that with 1-2 coats it can look super natural, but add a few more and wow volume!10/10 favourite. Mascara. EVER!
I initially bought this in the travel size as it was sold out in full, and was so impressed with the results that when it was in stock I bought 2 full size! Normally, I use lash primer, along with a heated curler and lash comb, but I'm trying to go more natural with my makeup so used this just on it's own. I have naturally long thick lashes (I do use lash serum) and this truly makes it appear like my lashes are much longer and thicker, very prettily fanned out and wispy, with a curl that looks natural. Since this is obviously impressive stuff used by itself, I can imagine that a couple of coats over primer and the help of a curler would be quite possibly too extreme! I'm very happy with how nice the formula is, just the right consistency, no hint of clumping, ... MoreI initially bought this in the travel size as it was sold out in full, and was so impressed with the results that when it was in stock I bought 2 full size!

Recently received a trial size from the hourglass counter at John Lewis in Bluewater. The sales assistant was lovely and gave me an extra one for my mum :)Having tried mascaras from many of the top premium makeup brands I was sceptical that this would be anything special.I was so wrong! I absolutely love this mascara. I have fairly long but sparse lashes and struggle to add volume without developing major clumps.This product works wonders in the volume department and adds lovely length without my lashes looking spidery.The brush is thick and consists of a multitude of fine fibre bristles, unlike the rubbery brushes that so many mascaras seem to favour these days. It tapers to a tip that is perfect for reaching the inner corner lashes.I found one coat does the ... MoreRecently received a trial size from the hourglass counter at John Lewis in Bluewater.

Also lasts all day without smudging.Really am impressed as is my mum!Am now going to purchase a full size once my trial size runs out :)
This mascara I have no bought for 3 loved ones in my life now. I am the type of person to buy a different mascara everytime one runs out, as there is so much on the market! I have long but very straight and thin lashes. I use rapid lash to help them grow and have done for years. Honestly this mascara really is amazing, and I will repurchase this along with the Lancôme lash idole forever!!! Only reason I gave it 4 stars is you HAVE to use a oil based remover to get it off as it’s so long wearing, I don’t mind this I just have to be gentle with my lashes. It doesn’t smudge or flake through the day which is key as I am a glasses wearer. It adds both volume and length with literally one coat. The dream would be if they released a brown shade as I am a redhead! Really ... MoreThis mascara I have no bought for 3 loved ones in my life now.
