Let’s dive into what you need to know about hypochlorous acid and why you should consider adding it to your skincare routine.
What is Hypochlorous Acid?
Hypochlorous acid (HOCl) is naturally produced by your body’s white blood cells to fight off infection and bacteria. Think of it as nature's disinfectant. It helps prevent the spread of harmful germs, promoting faster healing. Chemically, hypochlorous acid is a mild acid, made by combining salt, water, and vinegar via electrolysis—a simple process that creates this natural antibacterial agent.
While it’s found in some household cleaners and disinfectants, the version used in skincare is diluted to a safe concentration (100 parts per million) and formulated specifically for your skin. When used correctly, it’s incredibly effective at fighting inflammation and bacteria while being gentle on sensitive skin.
What Are the Benefits of Hypochlorous Acid?
Hypochlorous acid is a bacteria-fighting superhero, and it comes with a variety of skincare benefits. Here’s why it’s so loved:
Fights Acne
HOCl can prevent new acne breakouts and help heal existing ones by reducing inflammation and killing bacteria.
Reduces Redness
It soothes irritated skin and helps calm redness, making it a great solution for conditions like eczema, psoriasis, and rosacea.
Heals Sunburns
Spritzing your face or body with hypochlorous acid after sun exposure can speed up healing and reduce discomfort.
Hydrates and Refreshes
Some formulations also hydrate your skin, helping it look plump and rejuvenated.
Safe for Sensitive Skin
Since hypochlorous acid is a naturally occurring substance in your body, it's safe for sensitive skin and won’t dry out or irritate your skin like some harsher acne treatments (e.g., benzoyl peroxide).
In essence, hypochlorous acid is like the duct tape of skincare—its versatility makes it great for treating acne, soothing sunburns, reducing inflammation, and even keeping your skin hydrated.
Should I Bring Hypochlorous Acid Sprays to the Gym?
Absolutely! With all its antibacterial properties, hypochlorous acid sprays are becoming a must-have gym bag accessory. It’s not just for your face—it can help ward off body acne, reduce odor, and protect your skin from germs you come into contact with on gym equipment. However, if you can, stick to using a disinfectant wipe on equipment first (they’re typically alcohol-based and better for surface cleaning). But adding a hypochlorous acid spray to your routine is a great extra layer of protection.
Are There Any Risks?
In general, hypochlorous acid is safe when formulated for skincare and used as directed. It’s important to avoid using concentrated hypochlorous acid (like the kind you find in household cleaners) as it can cause chemical burns. Always make sure to use products that are specifically designed for skincare with a safe dilution, and avoid getting it in your eyes or mouth. As long as it’s properly diluted, you can use it daily without worrying about adverse reactions.

Start with a clean face to remove dirt and makeup.
Spritz

You can also use hypochlorous acid as a spot treatment for acne, a soothing remedy for sunburns, or even a quick hand sanitizer when you’re on the go.
Who Should Use Hypochlorous Acid?
Everyone can benefit from hypochlorous acid—whether you have acne-prone skin, eczema, or just want to give your skin an extra boost of healing. Even those with sensitive skin can enjoy the soothing benefits of hypochlorous acid without fear of irritation. If you have very sensitive skin, opt for fragrance-free products, and as always, if irritation occurs, check the ingredients for other possible irritants.
Hypochlorous Acid: The TL;DR

It’s now available in easy-to-use products that can help with acne, inflammation, sunburns, and more.
