There's waterproof—and then there's Japanese waterproof. At Rei Cosmetics, we've tried just about everything under the sun (and sea), and nothing compares to the staying power of our curated J-beauty eye essentials. This summer, we're spotlighting our most unbeatable waterproof heroes—the mascaras, eyeliners, and removers that are the eye products you'll want on standby.
We've all been betrayed by "waterproof" mascara that gives up halfway through the day. But my daughter just put our 3650 Waterproof Mascara through the ultimate test: a full day of swimming and snorkeling in the Pacific Ocean, plus hours of sun and the inevitable sand-everywhere experience. The result? Her lashes stayed perfectly defined and smudge-free through it all. The real proof? Every friend was asking what mascara she was wearing—and if you're reading this, now you know.
You'll find this level of waterproof confidence right here at Rei Cosmetics. Here are our picks for summer-proof perfection:

But Wait—How Do You Take It Off?
