The fresh-faced model always looks naturally gorgeous, so we made it our mission to get to the bottom of her skincare routine ASAP. Turns out, the star is a big fan of BeautyStat, the science-driven line founded by cosmetic chemist Ron Robinson (who is also a personal friend of hers). In a recent YouTube video, Bieber spotlighted the brand in honor of Black History Month, calling out a few of her favorite products. One to note? The Universal C Skin Refiner, which she described as one of her "holy grail" products that has "changed" [her] skin for the better. If it sounds familiar, it's likely because of its massive popularity on TikTok, with creators claiming the serum is the "best on the market." While Beautystat's been available on Amazon for awhile, it just debuted to beauty fans at Ulta. Intrigued? Read on. Ulta Buy It! BeautyStat Universal C Skin Refiner, $80; ulta.com and amazon.com For starters, this miracle worker is the world's first 20% vitamin C serum with stabilized L-ascorbic acid (the purest form of vitamin C), according to the brand, and that amped-up potency helps it deliver lightning-fast results (and helps justify the price). Vitamin C is best known for its effective brightening benefits, in addition to its ability to lift, tone, and protect the skin — and if this one bottle turned Bieber into a believer, we're more than willing to add to our cart, too.
