Hypochlorous acid sprays have become very popular recently as a gentler way to calm angry acne-prone skin. Fans (and skincare brands) rave about its antibacterial and skin-soothing properties especially for sensitive skin. This is of course very appealing to people struggling with active inflammatory acne breakouts but get irritation from traditional treatments. However, the expectation and excitement sour for a lot of people who actually try it. There’s a general feeling that it’s just another trendy fad whose benefits are little more than marketing hype. The good news is that this isn’t entirely accurate. Hypochlorous acid does have a role in acne management but it is frequently misunderstood. So before ditching your hypochlorous acid spray, it’s worth understanding what it can actually do for your skin. In this article, we look at what hypochlorous acid actually does. We also cover the best way to use it for managing acne-prone skin.
What is Hypochlorous Acid?
Simply put, hypochlorous acid is a molecule produced naturally by the immune system in our bodies. White blood cells make it as part of the body’s first-line defence against bacteria and other microbes. It can also be artificially synthesised for use in medicine and skincare settings. These formulations usually use hypochlorous acid at low concentrations in sprays or toners. This helps reduce acne-forming bacteria and inflammation on the skin. It’s really important to understand exactly how hypochlorous acid can treat acne in order to use it correctly. Basically, like antibiotics, it plays a role in controlling active inflammatory acne breakouts. However, it does not alter the underlying drivers of acne such as pore clogging and excess oil production.
How Can Hypochlorous Acid Spray Help Acne-Prone Skin?
The main value of hypochlorous acid spray in acne is to control active acne breakouts by reducing inflammation and bacteria overgrowth. This helps reduce the size, number and redness of pimples whilst helping calm irritated skin. It is also useful as a supportive ongoing treatment in cases where acne-prone skin has barrier disruption due to aggressive skincare treatments. Furthermore, some people may have chronic background skin inflammation due to reactive skin conditions like eczema or rosacea. These can worsen the severity of acne breakouts and make effective treatment difficult. With appropriate use, hypochlorous acid spray can help acne-prone skin by:
- Settling visible redness and irritation which also helps reduce the size of the pimples
- Reducing chronic background inflammation
- Supporting skin barrier function by providing another line of defence against microbial infections
- Calming skin to improve tolerance to irritating acne-modifying treatments like retinoids and exfoliating acids
What Can’t Hypochlorous Acid Spray Do for Your Skin?
Hypochlorous acid is often misunderstood because its calming effect can look like progress. Redness settles, irritation reduces and the skin feels more comfortable. However, this surface improvement does not reflect a change in the underlying behaviour of acne-prone skin. Hypochlorous acid acts on inflammation and microbial load at the surface, not on the biological processes that drive acne formation. When it is used instead of actual disease-modifying treatments, acne flare-ups continue because the core drivers remain fully active. The key limitations of using hypochlorous acid spray for your acne skin are that it doesn’t:
- Prevent Comedone Formation: Hypochlorous acid does not normalise follicular keratinisation or influence how dead skin cells accumulate within the pore. This is what causes microcomedone formation giving rise to whiteheads and blackheads which can later become pustules or even cysts.
- Reduce Sebum Production: Sebaceous activity remains unchanged. This results in increased oil (sebum) that helps clog pores and feeds acne-causing bacteria on your skin that cause inflammation.
- Address Hormonal Drivers: Androgen sensitivity plays an important part in many cases of adult acne. This is because it increases sebaceous gland activity which leads to more oil production.
- Replace Acne-Modifying Treatments: These work by altering follicular function over time. Hypochlorous acid spray simply dampens active inflammation due to bacterial overgrowth in the skin.
Another limitation is that because skin may appear calmer and active breakouts settle after using hypochlorous spray, it can provide false hope. Often people think they’ve found a miracle cure for their acne and so may stop or delay introducing more traditional acne treatments.
What’s the Best Way to Use Hypochlorous Acid Spray for Acne-Prone Skin?
The best way to use hypochlorous acid spray is in a narrow supportive role. It should be part of a wider skincare routine rather than your main acne treatment. The optimal way to use hypochlorous acid spray for acne-prone skin is for:
- Calming Inflamed Skin: It is useful for irritation, redness or sensitivity. This helps reduce the severity of acne.
- Supporting Tolerance to Actives: Retinoids like tretinoin, exfoliating acids and benzoyl peroxide are very important for managing acne but can be irritating. Hypochlorous acid can help calm the skin and make it better able to tolerate these traditional acne treatments.
As such, the ideal time to use it is during acute inflammatory acne breakouts. It also helps after skin procedures like extractions, reducing inflammation and bacterial overgrowth. For ongoing maintenance it can provide a supporting role to acne-modifying treatments like retinoids, azelaic acid and spironolactone.
So instead of ditching your hypochlorous acid spray, try using it as a supportive skincare ingredient in your overall acne routine. Its main value is during active inflammatory acne breakouts where it can calm the skin and reduce the appearance of pimples. Ongoing use as part of your regular routine can help reduce background inflammation due to reactive skin conditions. It also improves skin tolerance to more irritating treatments. Also always remember that as with anything in life, what works for one person may not work for another. Your skincare routine should be manageable, consistent and able to adapt to your skin’s needs.
