Get perfect peepers with the Hourglass Caution™ Extreme Lash Mascara, an all-in-one mascara that contributes to lifted, lengthened and defined eyelashes.

This mascara features a two-in-one brush that delivers length, volume and lift in a single stroke. Its tapered end reaches smaller and more delicate lashes easily, and it applies cleanly on bottom lashes without smudging onto the lower lashline. The mascara saturates the lashes from root to tip, creating definition with ease and precision.

The Hourglass Caution™ Extreme Lash Mascara is vegan friendly and cruelty-free. Its weightless formula is smooth, ultra-black and buildable, meaning it can be used to create both subtle and dramatic looks.

  • Saturates lashes from root to tip in a single stroke

Just the best

I work in events and this mascara has given me high-impact lashes from 7am-10pm throughout running huge, outdoor events in all weather (including, I will admit, VERY sweaty hot weather!). I could never go back to anything else. The travel size is also great, as I always find full-size mascaras dry out before I use them all!

Repeated purchase

I absolutely love this mascara. My natural lashes are relatively long so this just defines them beautifully. Before commuting to full size which is quite expensive, I went for the travel size and it actually lasted me months, so I repeated my purchase of a travel, which is a win in terms of cost saving, easy to throw in a purse and you have to change mascaras anyway once a few months. Will surely repeat my purchase.

If there was an additional star to the rating, this mascara would definitely get it!! I recently purchased this travel sized product for a weekend getaway. It made my eyes pop (in a very good way)! It was non clumpy and elongated my eyelashes so much that I couldn’t believe they were not eyelash extensions. Couldn’t recommend this more!

Excellent mascara

I received one of these in a beauty advent calendar and am very happy I did, as otherwise I doubt I would have tried it. Very good lash coating, lengthening, really black black colour - and I prefer travel sized anyway as I don't wear mascara all of the time, so full sized products often start drying out before I've used them up anyway. I will repurchase.
