The finished product, the Olive & June Hand Serum, contains hydrating hyaluronic acid, avocado and jojoba oils, mango and banana extracts (to exfoliate and brighten skin), and passionflower, which is also found in the cuticle serum.
Hyaluronic acid is the workhorse here, for moisturization,” says Ginger King, a cosmetic chemist unaffiliated with Olive and June, who reviewed the formula for us. She described the serum as a “basic formula,” which is pretty much all you need from a hand product.
It’s not the first hand serum on the market — Verso, Aveda, and even La Mer have versions — but the category is still fairly new. But Tuttle is dropping into the hand-care game as the entire world is paying more attention to washing their hands (and the skin issues that excessive handwashing can cause) than ever before.
According to Joshua Zeichner, the director of cosmetic and clinical research in dermatology at Mount Sinai in New York City, a hand serum can help address signs of aging on the skin. “If you have dark spots, crepey skin, or wrinkles, a hand serum may help brighten and strengthen the skin,” he says. Conversely, for peeling, cracked, or itchy skin, he suggests reaching for a bonafide moisturizer.
