Hailey Bieber loves BeautyStat Universal C Skin Refiner, and it’s on sale pre-Prime Day

These stars’ beauty shelves are prime real estate.

Hailey Bieber and Bethenny Frankel have both raved about BeautyStat’s Universal C Skin Refiner over the years — and in the lead-up to Prime Day, it’s a rare 20% off.

Frankel reviewed the product on TikTok in 2024, dubbing the formula “at the level.”

“What’s different about it is that it comes out a cream, but when you put it on your face it feels like a cloud … no other product that I’ve ever had feels like this in any way,” the podcast host raved of the bestselling vitamin C serum, which contains hyaluronic and ascorbic acid.

“It also tingles which makes me feel like the ascorbic acid is working … this is a functional product and I love it,” she added of the “unique” find.

Hailey Bieber’s on the same page, calling Universal C Skin Refiner her “holy grail” in a YouTube video in 2020. (“It has changed my skin,” she gushed.)

It’s not the only celeb-approved BeautyStat buy on sale right now, as the brand’s Universal Triple Action Daily Peel — another Frankel favorite — is also 20% off.

“I put it on and it smells exactly like the chemical peel that the woman comes over to do for hundreds of dollars, and it’s strong,” she mogul said on TikTok last September. “Give me 14 of them right now … I’m freaking out.”

And while it’s excluded from the current sale, BeautyStat’s C Lip Serum also earned Frankel’s stamp of approval; she called it “so creamy” and “excellent” in another TikTok this May, after discovering it from a member of her team.

Meanwhile, Serena Williams uses brand’s Peptide Wrinkle Relaxing Moisturizer, which she called “great” in her Vogue “Beauty Secrets” installment.

Whichever you’re planning to shop, just be sure to do so stat before deals end.
