We put Hourglass Unlocked Extension Mascara to the test after receiving a complimentary sample from the brand. Keep reading for our full product review. 

I am always on the hunt for the best mascara. Over the years I have tried nearly every formula from drugstore to luxury brands. While mascara is a permanent staple in nearly everyone’s makeup bags, the great thing about it is how it’s always evolving, to give us the results we truly desire. Known to transform eyelashes in just one application, I put the Hourglass Unlocked Instant Extensions Mascara to the test.

Ahead is my full review on this mascara along with all the reasons I might think it could very well be your next favorite formula.

About My Skin: I'm usually never without mascara

I am a daily makeup-wearer, and mascara is one of my favorite things to apply due to how quickly it wakes up my eyelashes and eyes. I’ve tried nearly every mascara formula out there, and my lashes have gone through cycles of being very long or needing to be trimmed down a bit due to their length. Products I tend to wear daily are mascara, foundation, concealer, brow gel, bronzer and blush, and sometimes a bold lip.

How to Apply: You’ll need at least two coats 

Applying this mascara was fairly easy, yet I needed a few coats to really see results. I started at the base of my lashline and wiggled the wand upward through my lashes to the tips, and repeated those steps a few times until I felt like I had applied enough product. I also like to angle the brush sideways to help individually comb through my lashes to separate them more.

The Results: You can feel the luxury

I needed to apply a few coats of the mascara before I really noticed the results. While applying the first coat helped to add length and definition to my eyelashes, I kept going to achieve the thickness and fullness I was after. I really like the wand and how short the bristles are, which made it easy to avoid any kind of clumping. It took me around two to three coats until I liked the way my lashes looked and had them looking noticeably thicker.

I didn’t notice much in the way of lengthening with this particular formula but definitely noticed more volume and separation.

When removing the mascara, you’ll need to use an eye makeup remover soaked in a cotton pad and press it on the lashes for a few seconds before gently rubbing it off. It took me longer to remove this formula versus others I’ve tried, and I noticed that it flaked onto my skin while removing, which you’ll want to make sure you completely wipe off.

The Value: On the pricier side

At $29, this mascara isn’t in the budget-friendly category, but could very well be worth the investment if you’re looking for a specific short bristled wand and a thickening formula. Unique wands that work on all lash types can take time to find. If the packaging is important to you, this chic metal tube is another reason to invest in a higher-priced item.
