Between the current heatwave, your sweaty commute and an intense gym session, it’s no surprise hypochlorous acid sprays are selling out. The best formulas ensure that a quick spritz helps to calm irritation, reduce redness and keep breakout-causing bacteria in check without stinging or stripping the skin.
Originally used in medical settings, skin expert Dr Lauren Jamieson explains that hypochlorous acid sprays “can be used for wound care, skincare, skin cleansing before procedures and general disinfection”. But while HOCl (the technical term for hypochlorous acid) has long existed beyond the beauty world, skincare brands have recently embraced its versatility, with the likes of Mario Badescu and Tower 28 launching facial mists that can be used as part of your everyday skincare.
These formulas promise to soothe flare-ups while helping to fend off blemishes before they appear, particularly during warmer weather, when sweat, SPF and pollution can leave skin feeling overwhelmed. Of course, not every formula lives up to the hype. So, after weeks of testing cult favourites and newer launches alike, I narrowed down the hypochlorous acid sprays I think are worth a spot on your skincare shelf.
