This miraculous, multipurpose, pH-balancing spray helps prevent skin irritation and redness. The star ingredient is something called hypochlorous acid, a soothing compound naturally produced by our white blood cells. Surfers have long used the acid to help calm their skin after difficult days in the waves; here, it’s mixed with just water and salt—the latter helps conduct the calming acid on skin—and put in a spray bottle to make it easy. It’s pretty magical and can be used multiple times a day, anywhere on your face and body, for an odorless spritz that feels just like water but delivers beautiful relief.
