You have to work quickly when applying the 3D mascara, as the fibers are intended to stick to the freshly applied product (so don't want to wait around for it to dry). The results? Fluffy (yes, fluffy), lengthened and voluminous lashes. The straight application wand proved to be a pro at reaching hard-to-get-to places (like the inner and outer corners of the eyes) and distributed a hefty amount of product onto my lashes to give my eyes noticeable drama. The brand claims that you'll "see up to a 500 percent increase in average volume with your first coat." While the mascara did amp up my lashes, I wouldn't say it boosted them by 500 percent. If that were the case, I'm pretty sure we'd all look like Jenna Marbles in her 100 coats video.

Just as I feared, this mascara was not kind to sensitive eyes. When I went to swipe on the fibers, the little hairs almost immediately started irritating my eyes. Because the wand contains a lot of product, a few hairs fell into my waterline and left me (blindly) searching for a Q-tip for the next two minutes to alleviate the burning sensation consuming my eyeball. However, once I removed the fibers from my waterline and swiped on the second coat of normal mascara to lock it in, my eyes were fuss-free and remained that way for the rest of the day. Of course, I couldn't stick with just one layer either — not once the 500 percent volume gauntlet was thrown down. Once my eyes calmed down, I swiped on a second coat of the normal mascara, followed by the fibers, and watched as my lashes became even more dense and flutter-worthy (with no irritation the second time around).

After applying the Younique Moodstruck 3D Fiber Lashes Mascara, I was pretty impressed with the lash-fluffing results, and I was curious to see if my plumped-up lashes would shed throughout the day or stay intact. After applying the 3D mascara around 8 a.m. and wearing it for a couple hours around the office, I did notice some fallout beneath my eyes. The fibers were so fine, though, that I had to look pretty hard to see them scattered about my under-eye area and on the top of my cheeks — and no one else seemed to notice them throughout the day. While there was some shedding (that's what I get for basically putting fur in my eyes), I have to give the mascara props for holding up during my gym session, which I decided I would fill with 20 minutes of heavy cardio followed by 15 minutes in a 200-degree sauna.

When I emerged from the sauna, my mascara was miraculously still in tact. There was a bit of fallout and smudgy eyeliner (understandably), but my lashes remained lifted and lengthened.

By 8 p.m. that evening, my mascara and extended lash length were still going strong. Though my lashes weren't the dark, dense, voluminous furry animals they were that morning , I did put them through a workout, intense heat, moist air and a 12-hour day without them melting off my face. Color me impressed.

Younique impressed me with their 3D mascara. The mascara definitely added density to my lashes, making them appear thicker and more voluminous — which is enough to make any girl feel sexy. And if you add two coats like I did, your confidence will be through the roof.

However, if you have sensitive eyes, you might want to reconsider accepting that Facebook invite to the Younique group. I'm not overly prone to irritation from mascara, but the fine fibers were enough to tickle my eyes in a way they did not appreciate, though once removed from my waterline my eyes were totally fine. Beauty is (temporary) pain?
