“I really just watch and read the fun stuff,” Sweeney, 24, told Refinery29 this week. “I saw this TikTok of this girl who uses this eyelash serum, and I ordered it.”

That serum turned out to be RapidLash, a time-honored, cult-favorite product that claims to make eyelashes thicker, fuller, and healthier in just weeks. Lo and behold, it worked; now, Sweeney’s routine isn’t complete without the stuff.

“I use it every day,” The White Lotus actress said. “Everyone has said something. I don’t ever tell anyone.”

The secret behind RapidLash is its mix of peptides and biotin, which promote eyelash health and fortify strands against breakage. The formula's Hexatein 1 Complex and hyaluronic acid, meanwhile, lock in moisture, keeping lashes looking and feeling softer.

Eyelash serums can actually work in the way that Sweeney says they do; board-certified dermatologist Joshua Zeichner, M.D. previously told Prevention that growth serums extend the growth phase of hair, leading to thicker, fuller lashes that could pass for a set of falsies.

“My makeup artist, Melissa Hernandez, was like, ‘Sydney, your eyelashes are longer,’” Sweeney recalled. “Then Donni, my makeup artist for Euphoria, was like, ‘We don’t even need to put eyelashes on you anymore.’”

Sweeney isn’t alone in her praise: Since RapidLash was released in 2008, reviewers have raved about its effects. “I am not a person who usually leaves a review, but this product is so well-deserving,” one writes. “It’s been less than two weeks and I’ve noticed a huge improvement, so I’m excited to see what happens in the next few weeks.”

“I am almost 60 and my eyelashes are short and stubby; this fills in the sparseness and makes my eyelashes so long that with mascara, they practically look like falsies,” another reviewer explains.

“I bought this after my lashes became sparse from lash extensions,” yet another says. “Within a month they looked thicker and fuller. Keep in mind you do have to keep using it if you want the results to last.”

So while we wait for Euphoria to return, we know exactly how we’ll pass the time: applying RapidLash to our lashes to make them as healthy and full as Sweeney’s.
