Welcome to Skimm Tested, where we put products to the test and then give 'em a report card. (Check out all of our tried-and-tested faves here.)

The assignment…

To see if Thrive Causemetics’ new Liquid Lash Volumizer™ Mascara ($25) creates a bold voluminous look that lasts all day — and if it’s actually worth adding to our daily makeup routine. Psst…Skimm’rs get 20% off.

Straight A’s in…

  • Instant volume. We were thoroughly impressed with how our lashes became bolder, fuller, and more voluminous in seconds. With just a few swipes, the high-impact formula coated each lash evenly, lifting and curling them. One person even asked if we were wearing false lashes. 

  • Staying power. As promised, it stayed on all day. It didn’t flake or smudge from the moment we put it on in the morning to when we took it off at night. We even worked out and spent time outside in warm temps, and the mascara stayed put.

  • Lightweight. You might forget you have it on. Until you look in the mirror. 

 Plays well with…

  • Anyone who wants dramatic lashes without the hassle or damage of lash glue.

  • Anyone looking for something more volumizing versus lengthening. 

  • Thrive Causemetics’ best-selling Liquid Lash Extensions Mascara. Layer the Liquid Lash Volumizer™ on top of it for a finished look. 

  • All lash types — our testers’ had a variety of lash types (long, short, dark, light, thick, thin).

Gets extra credit for…

  • Nourishing ingredients. The long-lasting formula is infused with three lash-loving peptides, sodium hyaluronate, and organic pea sprout extract to encourage fuller, healthier-looking lashes. 

  • The Custom Lift + Curl Dual-Bristle Brush™. It’s specifically designed to boost and hold a curl all day long. 

  • Thrive Causemetics’ Bigger Than Beauty® Giving Mission. For every product purchased, Thrive Causemetics donates to help domestic abuse survivors, veterans, people battling cancer, families seeking a path out of homelessness, under-resourced youth, and more. 

How we did our homework…

  • Skimm HQ’rs with a variety of lash types tested the Liquid Lash Volumizer™ over the course of a week. We applied it every day as instructed, using the shorter bristles to coat the lashes then using the longer bristles to comb through and fan out our lashes. We kept the mascara on all day and did multiple activities while wearing it to test its staying power. We kept track of how our lashes looked and felt with it on. We also noticed what it felt like to remove it. Our testers took note if it smudged or flaked throughout the day, which it didn’t. 


  • $25, and Skimm’rs get 20% off

  • Available in black (Brynn) and brown (Crystal)

  • Made with their one-of-a-kind Power Peptide Lash Booster™, which is a blend of three lash-loving peptides that deeply conditions lashes
