Hourglass Caution Mascara is not your mother’s mascara.

Hourglass makes some bomb products. Some of my favorites are Vanish Airbrush Concealer, Ambient Lighting Blush, and, of course, their beloved setting spray and powder. Really, I enjoy most all of their products and haven’t come across many that just don’t work. This includes Caution Extreme Lash Mascara, another one of my favorites. Let’s dive into Hourglass Caution Extreme Lash Mascara Review.

Promises vs. Performance: Hourglass mascara is a “powerhouse.”

Promising 400% more volume, dramatic length, and sky-high lift, Hourglass calls Caution Extreme Lash Mascara a powerhouse formula. It features an innovative 4D Amplifier brush that combines two brushes in one, and a tapered end to reach even the shortest lashes. The weightless formula has buildable ultra black pigment that won’t smudge or flake. Let’s see if this mascara defies “the boundaries of traditional mascara” as Hourglass claims.

My Review Thoughts: Hourglass Caution Extreme Lash Mascara

Caution Extreme Lash has a typical tapered, boar bristle brush. I love how dark and intense the black pigment is of this mascara. After just one coat, my lashes look bold and defined. This Hourglass mascara gives my lashes volume, length, and lift as promised. It’s easy to apply, clump free, and has the perfect sized brush for my smaller eyes.

I’ve worn this mascara on longer, 10+ hour makeup days and it holds up pretty well. I don’t get any flaking, but I sometimes get a bit of smudging. If you don’t set your under eyes, mascara can transfer a bit, especially if you have oiler skin/eyelids or you’re sweating. But, overall, the formula of Caution Extreme Lash is really solid and one of my favorites.

How It Compares: But is this Hourglass mascara the best?

I got to be honest in this review, Hourglass Caution Extreme Lash Mascara is one of my favorites. From the easy, clump free application to the (near perfect) all day wear, there isn’t much I don’t like about this mascara. In fact, the only true con I can think of is that the triangular packaging can be uncomfortable to hold! But, the intense black pigment effortlessly coats lashes, giving extreme volume, length, and lift as promised.

Compared to Chanel Le Volume De Chanel (rated ****3.8), this mascara performs similar. The biggest differences are the wands. Chanel’s wand is your typical thick, boar bristle brush. It gives a false lash effect without the need for falsies: volume, length, lift – it’s all there! The only drawback of this mascara is the amount of product for the price in the tube, otherwise this would be **** 4.5+ type of mascara.

And if you’re looking for a clean mascara formula, a few of my favorites include ILIA Limitless Lash for length, Caliray Come Hell or High Water for longevity, and Lawless The One and Done for volume. With each of these mascaras, you get an all day wear with minimal transfer and flaking. They also give you the longest, most wispy lashes!
