Unless you’ve been living under a rock and have zero access to social media, you’ve likely come across the trending skincare hero known as hypochlorous acid.

Despite its rather intimidating name, it’s been popped into school bags by mothers for their kids, taken on flights by avid travellers who refuse to let aeroplane air affect their skin any longer, and even parents of young children who are still in nappies – the antibacterial dream is suitable for all skin types and all ages.

We spoke to an expert in the field, Vicki Whetton from Within Skincare, to understand just what hypochlorous acid is, and how it works.

“Hypochlorous acid is a naturally occurring molecule produced by the human immune system. It plays a crucial role in fighting infection and promoting healing. It can be made by the electrolysis of salt and water to produce a very weak but effective acid,” explains Whetton. “When applied topically, hypochlorous acid offers a safe, non-toxic, and effective solution for cleansing, soothing and repairing skin.”

The benefits outlined by the skincare expert above are “particularly effective for those who wish to use it as a double cleanse, those out and about on the go, as well as after the gym or if you have problem skin such as acne or eczema.”
