PrimeLash Mascara is designed specifically for mature, thin, sparse lashes, and bare eyes, featuring a hypoallergenic and pH-balanced formula suitable for sensitive eyes. It’s vegan and cruelty-free, with credentials that support ethical beauty standards, while its lightweight texture prevents clumping or flaking for easy application. In contrast, Thrive Causemetics Liquid Lash Extensions Mascara is notable for its fiber-infused tubing formula, which is designed to significantly lengthen lashes. Its patented blend of orchid stem cell complex, Japanese pepper extract, shea butter, and castor seed oil aims to condition and improve lash health. Unlike PrimeLash, Thrive’s mascara is also free from parabens, sulfates, and phthalates, appealing to those seeking clean beauty options.
In summary, for individuals with sensitive eyes or who prioritize ethical beauty standards, PrimeLash mascara is an ideal choice. For those seeking dramatic lash length or a formula free of common additives like parabens, Thrive Causemetics mascara offers a compelling alternative.

Thrive Mascara feels light and gives a false-lash look. Its tubing formula coats each lash for length and definition. The result is bolder and more dramatic than Primelash.

Primelash Users Say
Annelise R primelash user says on primeprometics official website, “PrimeLash really impressed me. It goes on easily, and you can build it up for more volume. The fiber extensions make my lashes look fuller, and the wand helps separate them for a nice, fanned-out look. I also appreciate how easily it washes off. I don’t have to worry about smudging or mascara running when I work out, but it still comes off easily with water and gentle soap. Additionally, there are numerous color options available. PrimeLash has definitely improved my lash routine.”

Teresa P says on primeprometics official website, “This mascara really surprise me. It made my lashes look just like I was wearing falsies, and it came off easily at the end of the day. I’ll be buying it again for sure.”

Marcia H shared on the Prime Prometics website that she has a lot of stick-straight lashes, and this mascara works perfectly for her. She usually avoids buying products advertised online, but she’s happy she made this purchase. The mascara doesn’t clump and defines every lash. Although she’s 72, her lashes keep falling out and growing back, so they aren’t old, but they have lost their original color. She says this mascara truly delivers.

“I am 76 and have never used a better-performing mascara,” shared Lynda W on the Prime Prometics website. One swipe gives a light, feathery look. It dries fast, so you can add more layers for a bolder effect. Taking it off is incredibly easy. I’ll definitely buy more when I need it!

Hayley W says on primeprometics official website, I love this mascara. It defines and lengthens my lashes, stays put all day, and never smudges. The nourishing ingredients are a great bonus and have helped my lashes feel stronger. Thanks, Prime Prometics!
