"Our Dewy Skin Mist is still a beloved formula for nourishing the skin, but it can be a bit more moisturizing than people with oily skin have need for," explains Tatcha founder Victoria Tsai. "We wanted to find a lightweight way to help keep skin hydrated — an unmet need for friends with oily skin or living in humid climates."

Inspired by Okinawa "Kucha" clay, The Satin Skin Mist is formulated to be hydrating, balancing, and clarifying on the skin. While the Dewy Skin Mist is designed to give skin a glowing finish, The Satin Skin Mist is formulated to keep skin feeling fresh with a more velvety texture.

Here's how it works, exactly: Sprayed onto clean skin underneath makeup, the silk and Okinawa clay powders in the formula work to absorb any oil breakthrough that pops up during your day. Spritzing it on top of your makeup will have a similar effect, Tsai explains, helping to keep oil at bay and also acting as a sort of setting spray, providing a mattifying — yet still hydrating — finish. Before you apply the mist, you'll also want to give the pretty glass bottle a good shaking in order to mix the liquid and the powder that naturally settles on the bottom. It's designed to be paired with Tatcha's The Water Cream or a similar water-gel moisturizer. (We also like the Kiehl's Calendula Serum-Infused Water Cream.)

"The Satin Skin Mist and The Water Cream have the same active ingredients and the same skin-clarifying and hydrating benefits, both in oil-free formulas," Tsai says. "The Water Cream is ideal to use morning and night, while The Satin Skin Mist can be used on-the-go or over makeup to finish a look."

As I always do before testing out a new skin-care product for a story, I consulted a cosmetic chemist for an outside expert opinion. My biggest question: How can a face mist be both oil-absorbing and hydrating at the same time? The answer all comes down to the ingredients — specifically, Tatcha's proprietary hadasei-3 complex, which is a blend of three Japanese ingredients: Uji green tea, Okinawa Mozuku algae, and Akita rice. For clarification, this blended complex is infused into the Satin Skin Mist, in addition to the aforementioned Okinawa "Kucha" clay (as well as Japanese Wild Rose and Japanese Seagrass).

"Very smart of them [to use] the most famous, local ingredients," says cosmetic chemist Ginger King, who explained that each of these three places in Japan are known for these specific ingredients, making them the very best source on Earth for each one. "The green tea from Uji has higher antioxidant property than other green tea, [and] the Okinawa Mozuku is very moisturizing, [while] rice from Akita helps to brighten skin."

But what about the entire clay suspended in liquid business? It's legit, King says. "Tatcha's product uses silk powder for a satin-y feel, and kaolin clay to absorb oil, while the active ingredients (green tea, algae, and rice) nourish skin at the same time," she says.

As someone with very oil-prone skin, I was eager to give The Satin Skin Mist a try for myself. My face makeup routine on a normal day includes a tinted moisturizer and some concealer, then I finish off with a bit of pressed powder (since I know my skin is bound to get oily throughout the day). I even stash a powder compact in my purse at all times for touch-ups when my T-zone inevitably starts looking greasy circa 1 p.m.

I spritzed on The Satin Skin Mist onto my clean, moisturized skin then waited a minute or so for it to dry before putting on my makeup (per the directions on the bottle). And listen, I've tried lots of skin-mattifying products in my lifetime, thus far, and I was pleasantly surprised at how well this one works. It doesn't feel chalky on the skin, yet it seemed to help mitigate my afternoon forehead shine a bit. I can't say for certain whether or not it has earned a permanent place in my daily makeup and skin-care routine, but in high-humidity or for summer days spent outside, this face mist is ideal.
