Apply the Measurable Difference Lash Serum at night for longer lashes in no time. 

Birchbox Breakdown

Mascaras tend to fall in one of two categories: they either add volume or length. But with this innovative double-sided mascara, you don’t have to sacrifice one for the other. The wand features one smudge-free Volumizing Black Mascara and one Lengthening Fiber Black Mascara. Use them alone, or combine them together for a phenomenal fringe.

How it Works

This mascara doesn’t just coat your lashes with black pigment—it uses a two-pronged approach to boost the length and fullness of your fringe. One end of the wand has a volumizing rich black mascara, while the other contains a lengthening formula with flexible fibers that bind to the tips of your lashes.

How to Use

For a dramatic fringe, start with a lash-boosting coat of the volumizing mascara and follow with a second coat of the lengthening mascara. For demure come-hither lashes, experiment with a single coat of either formula.

Good mascara

Though the sample size was teeny weeny, I got a few good uses out of it and was pleased with this mascara. It gave me really good volume. I should just splurge and buy the full size because I have yet to find a drug store mascara that I like as much as this one.

Not my favorite
Purchased

I bought the full size Lashem double trouble mascara after trying the sample and I just didn't love it. It felt heavy and didn't go on very smooth. I eventually just stopped using it even though there was still product left. I also didn't feel like it extended my lashes all that much.

Smudges

I loved this mascara when I first put it on, but then it began to smudge under my eyes in the first couple of hours. It really goes on nice and smooth, but the raccoon eye is something I'd prefer not to sport.

Clumpy

This product went on my eye lashes clumpy, and then after a few hours (3/4) I would find to have black marks under my eyes. A few times this mascara chipped off and irritated my eyes as well. I was not happy with this sample offer in my box this month.

Smudged a bit
Purchased

I love how it goes on, but, I small within a few hours black under my eyes. It's okay, totally does what it says, but didn't love the black eye look.

Terrible

The sample tube was super small and there was hardly ANY of the product inside of it. Honestly, I was able to get only about 2 real uses from this mascara. Oh, and the brush was way too small.

This is a case where providing a sample of the product will actually detract from the sales of the full sized version.

great
Purchased

This is really a great mascara . I loved the sample from my box , but when I purchased the full size I was even more impressed . I use the lengthening side during the day and just add the volumizing on top for night . My eyelashes have never looked so full !

Just okay

The sample size oh the mascara was very small. I had a hard time using the very short wand to apply. The fibers also seemed to irritate my eyes.

Not great

I really did not like this mascara. The "fibers" made my eyelashes look clumpy and did not feel good during application. It did not apply smoothly or easily and I didn't notice any noticeable difference in wearability throughout the day.

No!

This product gave me the forbidden " raccon eyes" and did NOT hold up in the heat, I also found the wand hard to use becauseof its size. I Would not purchase in the future
