Should I add hypochlorous acid to my skincare routine?

A spray after the gym. A bottle in your handbag. A quick step between cleansing and moisturising. Hypochlorous acid is finding a place in everyday skincare because it offers something useful: antibacterial action in a lightweight formula that can suit sensitive skin.

If your skin is prone to breakouts, visible redness or feeling unsettled, a well-formulated hypochlorous acid mist can be a useful addition to your routine. The appeal is an easy way to help keep skin feeling calm and refreshed without adding another heavy layer.

But the quality of the formula matters. Hypochlorous acid needs to remain active to do its job. How it is made and what happens to it inside the bottle can affect how effectively it works when you use it.

Hypochlorous acid is a substance your white blood cells produce as part of the immune response. One of its roles is helping to destroy microbes.

In skincare, it is used in carefully formulated solutions for its antibacterial properties. Despite the word “acid”, it does not work as an exfoliating acid such as glycolic acid. You are not adding a peeling step to your routine.

An ingredient list tells you what went into a product. It does not, by itself, tell you how much active hypochlorous acid remains when you spray it onto your skin.

Laboratory research has shown that light, heat, air exposure and substances in the solution can affect hypochlorous acid stability. In the same study, chemically depleted solutions showed markedly reduced antibacterial activity.

This is why manufacturing expertise matters alongside the ingredient list.

If hypochlorous acid breaks down in the bottle, less is available to act on bacteria when you apply it. That can reduce the antibacterial performance you bought the product for.

Eternal Skincare works directly with a specialist British manufacturer that holds the scientific dossiers supporting regulated hypochlorous acid applications.

These dossiers contain the evidence used in the regulatory assessment of the active substance. Other suppliers seeking to rely on those dossiers obtain permission through a letter of access. We work directly with the specialist behind that evidence.

That relationship matters because producing hypochlorous acid requires an understanding of both its antibacterial action and how to preserve its activity.

Our experience with hypochlorous acid extends beyond everyday skincare. The team behind Eternal Skincare also supplies hypochlorous acid products to dermatologists and luxury spas.

We bring that experience, together with our specialist British manufacturing partnership, to the Facial Mist you use at home. Our focus is on what matters when you spray it: a carefully formulated product that preserves the active ingredient responsible for its antibacterial action.

Our Facial Mist is a cosmetic skincare product. The dossier framework relates to biocidal uses and does not constitute approval of the mist’s cosmetic benefits. Its relevance here is the scientific and manufacturing experience behind our choice of partner.

These were studies of specific products and uses, rather than tests of Eternal Skincare’s Facial Mist. They help explain the scientific interest in the ingredient, but their results cannot be transferred to every bottle containing it.
