Prime Prometics vs. Thrive Causemetics: Which Mascara Does a Makeup Artist Recommend for Mature Women?

As a professional makeup artist, I’ve come to understand that finding the right mascara isn’t just about adding length or volume for mature lashes—it’s about addressing the unique needs of thinning, delicate lashes and hooded, watery eyes. A good mascara should enhance what you have while being gentle and effective.

I’m always hearing about Prime Prometics PrimeLash Mascara and Thrive Causemetics Liquid Lash Extensions Mascara, so I decided to try them both to determine which mascara would be best for maturing lashes. Here’s what I found:

For healthier, stronger lashes… Prime Prometics

Thrive’s mascara provides temporary lash enhancement but doesn’t actively improve lash health. Prime Prometics goes the extra mile with a formula infused with bioactive nutrients to assist lash growth and strength with each swipe of the mascara wand. The more product used, the longer and stronger lashes grow, making it more than just a makeup product—it’s a lash care treatment.

For smudge-proof wearability… Prime Prometics

Mature clients often struggle with mascara smudging or transferring, especially with sensitive and droopy eyes. Thrive’s mascara held up well in controlled settings but I noticed minor smudging under the eyes by the end of the day—a deal-breaker for clients with hooded or oily lids.

Prime Prometics’ no smear, no smudge formula stayed intact all day. Whether exercising or running errands, this hypoallergenic mascara refused to budge — no touch-ups needed.

For lift and volume that looks natural… Prime Prometics

My mature clients want a mascara that delivers lift and volume naturally without having to deal with lash extensions. Thrive’s mascara lengthens beautifully, thanks to its fiber technology, but it can be tricky to layer without creating a slightly stiff feel.

But the real winner here is Prime Prometics’ PrimeLash Mascara, which not only lifts and elongates lashes by 3x but also keeps them soft and natural-looking. The buildable formula builds volume without clumping or brittle lashes, perfect for any occasion.

For a variety of colors… Thrive Causemetics

For my more adventurous clients, Thrive Causemetics’ seven mascara colors, ranging from the traditional black to a vibrant pink, are the perfect addition to their makeup routines.

Though PrimeLash only comes in three colors, the shades are rich and deep, perfect for a daily routine. If you’re looking for a little bit of spice to your eye makeup, Thrive offers a greater range of colors. 

For easier application… Prime Prometics

The wand makes or breaks a mascara, especially for clients with sparse or thinning lashes. Thrive’s mascara uses a straight, traditional wand that doesn’t always grip the finer, shorter lashes of older lashes, making it difficult to achieve full coverage without layering excessively.

PrimeLash comes with their Magic Wand, a uniquely designed brush that effortlessly reaches every lash. It gives an even coat without tugging or clumping, perfect for fragile lashes and delicate eyelids.

For vegan, cruelty-free beauty products… Both

Both Prime Prometics and Thrive Causemetics are committed to clean beauty, which is essential for sensitive eyes and skin. Both are cruelty-free, vegan, and free of parabens, sulfates, phthalates, and synthetic fragrances.

It’s reassuring to know that both brands uphold high standards, and I feel confident recommending either to my clients from a safety and ethical standpoint.

For the best value… Prime Prometics

My clients appreciate products that are both effective and beautiful, and PrimeLash fits the bill. The PrimeLash mascara is priced at $28, which is truly an amazing price for the lash-care benefits, superior wand design, and smudge-proof formula. 

Thrive Causemetics mascara also costs $28, but it just cannot deliver the same value for the money — especially when you get free shipping for Prime Prometics orders over $60. 

My clients cannot get enough of PrimeLash

While Thrive Causemetics offers a solid mascara option, Prime Prometics PrimeLash Mascara is the clear winner for maturing lashes. It’s the only mascara I’ve found that truly addresses the unique challenges of aging lashes while delivering long-term care. 

From its smudge-proof, long-lasting and lash growth-boosting formula to its innovative Magic Wand, it’s a standout choice for anyone looking to enhance their lashes without lash extensions. So if you’re over 50 and looking for the best mascara for mature eyes, trust me: this is the one you’ve been waiting for.
