Eventually my project was derailed by a run-in with vinegar eels (nightmare fuel), but I remain a sucker for the drink's fermented, acidic bite. And according to Japanese skincare brand Tatcha, kombucha isn't the only way to reap the benefits of fermentation: The technique plays a key role in the brand's wrinkle-minimizing Dewy Serum. The serum doesn't beat around the bush with its name, and calls in double-fermented Uji green tea, Akita rice, and Okinawa algae to provide high levels of exfoliating lactic acid. Together, the brand says those three ingredients comprise 73 percent of the serum, so the periwinkle bottle is a potent resurfacer. Combined with moisture-drawing hyaluronic acid, plumping sugarcane-derived squalane, and hydrolyzed collagen and elastin, the effects have earned the serum over 1,200 five-star ratings on the brand's site. "My skin looked luminous and dewy, and fine lines around my mouth, eyes, and forehead seemed to disappear," wrote a fan of the "definite" plumping action they saw within weeks. A 52-year-old reviewer confirmed the "unbelievable" difference in their wrinkles and newly even skin tone, and a third person said their skin is the most hydrated it's been in 15 years.

Its mineral sunscreen has garnered nonstop laurels since launching in March; Jennifer Aniston uses its lip mask; and its concealer-eye cream hybrid is a "miracle product," according to well-versed editors. The Dewy Serum plays up that same multitasking facet, toeing the balance between an exfoliant, moisturizer, and anti-ager that leaves wrinkles "practically gone." "My skin looks so new and young, I was asked for my ID the other day," wrote one user, and another person said their formerly "very visible" pores were distinctly reduced by the fragrance-free formula. Others wrote that their redness is now less pronounced, as are their under-eye circles, and a self-described "very picky" esthetician dubbed it a plumping "drink of hydration" when swiped across their lips. Between the gorgeous bottle, smart ingredients, and fast results, the Dewy Serum's hold on Tatcha's best-seller list is easy to understand (per the brand's website, it even outranks the beloved lip mask and Meghan Markle-approved Rice Polish). If you'd like to try the exfoliating and moisturizing wrinkle-reducer, the Dewy Serum is $88 at Tatcha's website and Sephora.
