It's one of just a few must-have products in her low-key beauty routine.

Future royal Meghan Markle has been in the spotlight for quite a while thanks to her longtime gig on USA Network's Suits and starring roles in a number of Hallmark movies. But, with the recent announcement of her engagement to the world's most eligible bachelor, her fame has suddenly (and not surprisingly) catapulted to new heights.

Unlike Kate Middleton who spent much of the time prior to her royal engagement out of the spotlight, Meghan has already given us a number red carpet appearances and media interviews to pore over, including a 2014 interview with Allure magazine wherein Meghan shared some of her best kept beauty secrets.

While she described her skincare and makeup routine as relatively low key, she did manage to give us the secret to her envy-inducing lashes—and it's not just good genes. The hero product is RevitaLash Advanced Eyelash Conditioner ($98), an anti-aging conditioning serum beauty insiders swear by for longer, stronger, and essentially falsie-appearing lashes.

Though it was years ago that Meghan cited the hypoallergenic formula as the source of her longer-than-ever lashes, our bet is it's still a mainstay. Women both stateside and across the pond can all agree that once we find something of worth (whether it's a product or a prince) we tend to hang on to it. And, judging by Meghan's adoring smile and stunning eyes peering from beneath her thick, fluttery lashes, she agrees on both counts.
