Both of these eyelash primers are hugely popular online. I picked up the KATE version early last year and the Ettusais one around August of the same year. Many shoppers struggle to choose between the two, so I hope this comparison review can help you make up your mind.
Let’s start with the KATE eyelash primer. Its formula is white and infused with plenty of black lash-like fibers. It features a relatively large applicator wand, similar to that of a regular mascara. I have naturally short lashes, and a visible white coating remains on my lashes after applying KATE. The embedded black fibers add noticeable length and volume to lashes. Be sure to wait until the KATE primer dries completely before layering on mascara; once set, it genuinely lengthens and thickens your lashes.
The Ettusais primer comes with a totally different applicator shaped like a tiny lash comb, and its pale blue-white texture is lighter in consistency than KATE’s. On lazy days when I skip mascara entirely, Ettusais works perfectly worn alone, leaving no unsightly white residue on lashes unlike KATE. It separates each lash neatly for a clean, fresh finish.
Overall, the end results of the two primers are fairly comparable, with only one key difference: KATE delivers noticeably fuller volume, while there is barely any gap in lengthening effect.
Summary
Loaded with abundant fibers, KATE’s formula sits more prominently on lashes and creates extra length and thickness once mascara is applied over top.
Ettusais boasts a sheer, lightweight formula with fewer fibers, offering a lighter wear and leaving lashes crisp and tidy after mascara application.
Opt for Ettusais if you prefer going without mascara, as KATE’s white paste looks unnatural when worn solo. The two perform equally well in terms of staying power.
A key tip for both products: always allow the primer to fully dry before applying mascara.
