Brag alert! I mastered the cat eye at a very young age. I credit (or blame, depending on whether you think I was too young) years and years of practice since I was 13. Basically, I was Kat Von D before she realised she was going to be that Kat Von D. By early adulthood, I can produce symmetrical flicks in no more than five confident strokes. It was a sight to behold.
Here's the problem: I got so used to how bright and large my eyes appeared, I was starting to hate my face without cat eyes. My solution was drastic — I didn't let myself use liquid eyeliner for almost half a decade, unless it was a special occasion, such as evening weddings which required heavier eye makeup, photoshoots, etc. They didn't come frequent, so my skills deteriorated with time.
Lately, Marc Jacobs Beauty Highliner Liquid-Gel Eyeliner has made me feel like I'm back on track. The tip of the brush applicator is so sharp, so easy to control, I no longer make any blunders, as though my eyeliner skill is back to what it was. This is especially useful with the metallic shades, which I use to draw floating, wandering graphic lines and little dots above my thicker grounding black strokes. Speaking of the black… while Blacquer's pigment is rich, the shade is not nearly as deep as the abyss as I'd like. It's not that big an issue, however, since I always layer my liquids on top of the OG Marc Jacobs Beauty Highliner Gel Eye Crayon Eyeliner for a bold finish.
Oh yeah, it's definitely waterproof and smudge-proof too. I sobbed away rewatching watching Toy Story 4 on a plane (I'm not ashamed) but my eyeliner stayed as perfect as the movie's end.
