As if a serum weren't lightweight enough, this serum takes it to the next level of weightlessness with its mist format, which delivers all the hydration of a body lotion but without the long absorption time. This refreshing serum mist pairs Hyaluronic Acid with antioxidant-rich botanical extracts (from Watermelon, Microalgae, and Licorice Root, among others) to defend skin against free radicals, making it a winner if you're spending the day outdoors.
