A hypochlorous acid might sound like something you’d only encounter in a science lab, but in the world of beauty it’s become everything from a gym bag essential to a sensitive skin saviour. For me, Isoclean’s iteration of the spray is the cream of the crop.
Naturally produced by the body as part of its immune response, hypochlorous acid is often used in clinical settings in place of traditional antiseptics. This is largely because it helps to keep skin hygienic after facial treatments and minor procedures, where maintaining a calm, non-irritated barrier is key. However, in a non-professional setting, it’s typically used as a lightweight mist to calm, clarify and freshen the skin.
With heatwaves, gym sessions and general day-to-day grime all taking their toll on skin, these sprays have taken up permanent residence in many skincare buffs’ routines. I’ve tested numerous hypochlorous acid mists through the years, with some costing near to £30 – but it’s Isoclean’s £14 formula that’s consistently improved the state of my skin.
It’s completely odourless, incredibly lightweight and sits invisibly under make-up without causing separation. With a product that’s so simple, where formulas can often feel interchangeable, this one stood out for its efficacy and reliabiliy when used regularly after exercise or on particularly sweaty days. Here’s why I recommend it.
