Dewing It

Tatcha Is Adding a New Dewy Serum to Lineup and I Tested It on My Dry, Winter Skin

The latest product in its beloved Dewy line is the only thing protecting my complexion from the harsh heat of my radiator.

My skin is like a drooling dog waiting for a treat whenever I pull the Tatcha The Dewy Serum out of my bathroom's medicine cabinet. After a long night of sleeping in an arid, radiator-heated room, the milky, floral serum replaces all the moisture that was sucked out of it like dehydration never even happened. 

Wait, I should probably back up for a second. I just buried some major news in there: Tatcha is about to add a serum to its beloved Dewy lineup. Although it's not launching until Tuesday, December 22, Allure got exclusive details on The Dewy Serum. 

After three years in the making, The Dewy Serum joins the Mario Dedivanovic-inspired The Dewy Cream, which even Selena Gomez swears by, as well as the Kim Kardashian-approved Skin Mist and the ultra-thin sheet mask

The prior Dewy launches give complexions an instant glassy (or even dolphin skin) effect with the help of Tatcha's proprietary Hadasei-3 complex, which features antioxidant-rich Japanese rice, algae, and green tea extracts. All are double-fermented to unlock their fullest potential of benefits, Sparacio says. 

The serum, on the other hand, works behind the scenes to maintain that enviable my-skin-is-so-hydrated-it-looks-wet look. Out of all the Dewy products, the new serum packs the highest concentration of the complex — 73 percent to be exact, compared to 13.4 in The Dewy Cream, Rose Sparacio, Tatcha's vice president of product innovation, tells Allure

Let's zoom in on each extract in the complex, shall we? Rice is rich in essential fatty acids to help with moisturizing, says cosmetic chemist Perry Romanowski. Algae, on the other hand, can be an anti-inflammatory when it's fermented, as it's made up of mostly carbohydrates, he adds. Green tea can also reduce irritation, thanks to its polyphenols. "They're like fire extinguishers, putting out inflammation caused by environmental free-radical damage," according to New York City-based board-certified dermatologist Joshua Zeichner. Basically, the complex is a recipe for calm, nourished skin. 

Fermentation also causes the extracts to release lactic acid, which gently smooths away roughness while drawing moisture into skin. This double-duty action of exfoliating and hydrating is what powers the serum, Sparacio says. Without it sloughing away flakes, the hydration has nowhere to go. "You can moisturize all you want, but you're really not doing anything because you have all of these dead skin cells hanging on, hogging up the room for all of these new, healthy cells below them," she explains.

The hydrating elements are bolstered by plant-derived hyaluronic acid and squalane straight from sugarcane. Not only do they help plump skin, but they combine with the Hadasei-3 complex to also ensure your skin's moisture barrier is in tip-top condition during the chilly months — and beyond. For those unfamiliar with this part of your skin, it's basically a security system. At its best, the moisture barrier protects from irritation, fine lines, and dehydration by retaining moisture and keeping skin dewy and smooth. 

The only oil spiking The Dewy Serum is crambe abyssinica seed oil, which is drawn from a mustard-related plant with a high level of fatty acids to help skin lock in moisture, says Romanowski. Why did Tatcha pick this oil in particular? It's lightweight, non-greasy, absorbs quickly, and "makes it very easy to layer with other products," Sparacio adds. (I can attest to this. I have acne-prone skin, and so far, so good.) "Dewy Serum allows you to prime the skin and bring the skin to its functional level."

So after you slather on The Dewy Serum, you can reach for your favorite vitamin C serum or moisturizer. You can also blend foundation over it without any piling happening. "The Dewy Serum helps makeup grab onto skin and gives it a naturally radiant finish," makeup artist Daniel Martin, who is also Tatcha's global director of artistry and education, tells Allure. "I'll also mix it with full-coverage foundation or concealer to sheer out the coverage and give it a more life-like finish."

Ready to make Tatcha's The Dewy Serum a part of your winter skin-care routine? Well, you'll have to wait until December 22 to add it to your cart on tatcha.com and sephora.com for $88, but you can get a head start on shopping it if you have Sephora's mobile app. A pre-sale will be running on December 21.
