If you spend any time at all in the beauty circles of social media, you may have noticed that hypochlorous acid sprays are the talk of TikTok. Content creators are using them to calm angry skin or refresh it post-gym, for example—one buy in particular that you may recognise is Tower 28’s SOS Spray, which has dozens of videos dedicated to its reported skin-soothing abilities. But it's also well loved as a product for acne treatment.
Last year, the skincare ingredient was forecast to surge in popularity in 2024 and, indeed, Google trends data shows that searches for hypochlorous acid saw a huge uptick from the end of March and throughout April, suggesting interest in similar face mists is on the rise.
