After transforming the way we consume smoothies, salads and even chips, health-food-of-the-moment kale is now bringing its super-detoxifying powers to the topical realm, appearing in several skincare and nail products. (Not surprisingly, since the vitamin A- and E-rich cruciferous has already been proven to boost hydration, elasticity and collagen production when ingested.)This month, Éminence Organics introduces its new Citrus & Kale Potent C+E Serum and Masque, which tap into kale’s anti-aging benefits to help skin look brighter and more even while combating free-radical damage. Across the pond in the U.K., the dermatologist-developed vegan brand Nourish includes kale in the Revital-Eyes cream to reduce the appearance of fine lines and crow’s feet.And, this fall, Nails Inc. will debut Nailkale, a range of keratin-strengthening polishes formulated with the green. Backed by fashion darling Alexa Chung—who appears as the face behind the lacquers—we think it’s safe to say that kale is cool.
