What is Hypochlorous Acid?

Hypochlorous acid (HOCl) is a naturally occurring compound in the human body, produced by white blood cells to fight off infections. Recently, it has gained popularity in the skincare world for its impressive antibacterial and anti-inflammatory properties.

HOCl is a weak acid made up of hydrogen, oxygen, and chlorine. In skincare, hypochlorous acid is used in its synthetic form, created through the electrolysis of saltwater.

Skin Benefits of HOCl

One of the most notable benefits of hypochlorous acid is its ability to help those with acne-prone skin. It works by eliminating the bacteria that cause breakouts, such as Propionibacterium acnes (or Cutibacterium acnes), without harm to skin cells. This makes it an excellent option for those with sensitive skin. Additionally, hypochlorous acid helps reduce the appearance of inflammation, redness and irritation associated with acne. Beyond acne, hypochlorous acid can help with conditions like folliculitis, eczema, and rosacea by reducing harmful bacteria and promoting skin healing.

How to Use Hypochlorous Acid

Hypochlorous acid is typically available in spray or mist form, making it easy to incorporate into your skincare routine. It's best to apply it after cleansing and before applying serums or moisturizers. You can also use it mid-day over makeup or after a workout to refresh and cleanse your skin of bacteria.

Safety and Precautions

While hypochlorous acid is generally safe for most skin types, it's always a good idea to do a patch test before using any new skincare product. If you experience any irritation, discontinue use immediately. As with any skincare product, it's important to follow the instructions on the label and consult with a dermatologist if you have any concerns.
