At this point, it feels like a new beauty product goes viral every other week. The cycle is predictable: Influencers start raving about a new launch, causing it to sell out almost immediately, and only after months of waiting (and finally snagging a restock) do we find out whether the rave reviews were legit or just another successful marketing campaign. Many of our favorite beauty products do pass this test—the Rare Beauty Soft Pinch Liquid Blush, Phlur Vanilla Skin, and Patrick Ta’s Foundation, to name a few. But just as often, viral products prove to be… a little lackluster. After years of hearing hype around the cult-favorite Thrive Causemetics Liquid Lash Extension Mascara, I decided it was finally time to see which camp it falls into.
From my favorite influencers to my best friend, I’ve been seeing and hearing rave reviews about this mascara for what feels like the better half of a decade. The sole reason I’d yet to try it? The Thrive Causemetics Liquid Lash Extensions Mascara is only available to purchase directly from the Thrive Causemetics website. Despite usually gravitating toward products that have ease of access (read: can Sephora deliver it to me in two business days?), my curiosity was enough to finally place an order to see if the 50,000 five-star reviews are warranted. Here are my honest thoughts:
The Thrive Causemetics Liquid Lash Extensions Mascara uses a tubing formula that wraps each lash in a coat of product to create length, curl, and definition. It’s also formulated to be flake-, smudge-, and clump-proof, all while remaining easily removable.

About Thrive Causemetics
The goal of Thrive Causemetics is to “to elevate your daily routine with science-backed solutions that go beyond beauty,” according to their website. Their formulas are 100% vegan and cruelty-free, and are free of parabens, sulfates, phthalates, latex, and synthetic fragrances. They also donate a portion of all purchases to one of 550+ nonprofit partners across the U.S.
About the Thrive Causemetics Liquid Lash Extensions Mascara
The Liquid Lash Extensions Mascara features a tubing formula that wraps each lash in a lightweight, water-resistant tube, aiming to provide long-lasting and smudge-proof results. (If you aren’t familiar with tubing mascaras, they work by creating tiny, polymer tubes around each lash, rather than simply coating them with pigment like traditional formulas.) While not waterproof, the formula is water-resistant, meaning it’ll survive the elements (sweat and rain included), but doesn’t require a waterproof makeup remover to take off.
The Liquid Lash Extensions Mascara is available in six shades, including black, brown, green, pink, and blue.
Key Features and Benefits
In addition to its cruelty-free and vegan formula, the Thrive Causemetics Liquid Lash Extensions Mascara is also free of synthetic fragrance, and according to Thrive Causemetics’ website, has been tested and approved by dermatologists and ophthalmologists for sensitive eyes and contact wearers.
My Review of the Thrive Causemetics Liquid Lash Extensions Mascara
About my lashes
My eyelashes are medium length, and unless I curl them, tend to lay stick straight. My dream mascara would lengthen, curl, add a little volume, and, most importantly, stay in place throughout the day. Bonus points are awarded to all mascaras that actually maintain the curl left from my lash curler throughout the day.
Usually, I apply what I think is a great coat of mascara, only to get a glimpse of myself a few hours later and notice that my lashes have all but disappeared. How is it possible to leave the house with lashes that rival the look of extensions only to look as though I have no lashes at all later in the day? I’ve yet to find a mascara that looks just as good when it goes on as it does later in the day when I take it off, but based on the rave reviews for the Thrive Causemetics Mascara, I had really high hopes.

How the Thrive Causemetics Liquid Lash Extensions Mascara Performs
Application
The Thrive Causemetics Liquid Lash Extensions Mascara has a stiff plastic wand with shorter bristles, which made it easy to apply on both my upper and lower lashes. After wiggling the brush between my lashes and combing upward, I was able to get the length, curl, and volume I’m after with a single coat of product. I also immediately noticed that my lashes weren’t left with any clumps whatsoever.
If I’m going out for the night or aiming for a more dramatic look, this mascara’s formula dries down just slow enough for me to go back in with a second coat if I feel like it’s needed. The one drawback I do sometimes experience is that the product gives me so much length that it can transfer to my upper eyelid during application; however, a quick wipe with a Q-tip once the product has dried eliminates it immediately.
Wear
For me, what really seals the deal on a mascara is its staying power and longevity. As I mentioned, despite doing everything in my power to get them to hold a curl, my lashes are stubborn and like to revert back to straight. The Thrive mascara, however, combats this problem beautifully. While I notice a smidge of the initial volume fades throughout the day, my lashes look significantly better at the end of the night with this mascara than with others I’ve tried.
Removal
Obviously, I love the idea of a waterproof mascara, but the pesky removal is enough to make me choose to deal with the risk of smudging throughout the day instead. I love that this mascara has a water-resistant formula, so it stays in place all day, but also easily removes easily. It doesn’t require scrubbing or makeup removers—just a little warm water makes it slide off the lashes with no residue left over.
Final Verdict: Is Thrive Causemetics Liquid Lash Extensions Mascara Worth the Hype?
This is truly the best mascara I’ve ever put on my lashes. It provides a dramatic look that lasts all day, and after years of saying, “How different could it really be?” to every video of it that crossed my For You page, I finally get it. I started this by saying I really don’t like buying makeup products that I can’t easily snatch from a major retailer, but I’ll be making an exception for the Thrive Causemetics Liquid Lash Extensions Mascara moving forward.
