Hypochlorous acid, classified as a weak acid in chemistry due to its low pH level (similar to citric acid), possesses remarkably potent antimicrobial properties. To put it into perspective, it is approximately 100 times more powerful than bleach. You might recognize it from diligently sanitizing surfaces with Clorox wipes during the global shutdown. Hypochlorous acid HOCl, denoted by chemical symbols, is commonly utilized in various applications such as surface cleaners, pool treatments, and facial cleansers. While the latter may seem unconventional, it's true: this disinfectant also plays a role in your skincare products.
Prior to considering applying Clorox on your face, refrain from doing so. Cosmetic chemist Ginger King emphasizes a significant distinction between the hypochlorous acid present in household surface cleaners and that used in facial mists. She emphasizes, "It must be diluted to 100 parts per million before it can be deemed safe for skin application." King continues, stating that skincare brands take measures to dilute the concentration and conduct safety testing to guarantee consumer well-being.
When appropriately diluted, hypochlorous acid proves to be potent against harmful bacteria while remaining gentle on the skin, including sensitive skin types. Skin experts actively endorse the use of products containing hypochlorous acid to combat prevalent bacterial skin issues like acne, eczema, and psoriasis. Essentially, it acts as a disinfectant for your face, effectively diminishing inflammation and expediting the natural healing processes of your skin.
You don't have to take gradual steps to incorporate hypochlorous acid into your skincare routine, nor do you need to be concerned about potential adverse reactions – you're already benefiting from it daily. This is because your skin naturally generates hypochlorous acid, which is produced by your white blood cells as a defense against infection and bacteria. In the event of a cut or scrape, hypochlorous acid steps in to prevent harmful germs from entering.
At some point, chemists discovered a method to package HOCl by combining salt, water, and vinegar, enabling them to produce hypochlorous acid in large quantities.
Today, hypochlorous acid is a common ingredient in facial cleansers, serums, creams, and sprays."A product that contains hypochlorous acid will typically be clearly labeled, but you can always verify by checking the ingredients list." Just look for HOCl.
We consulted with several skincare experts to provide you with comprehensive information on hypochlorous acid and how to effectively incorporate it into your skincare routine. Here's everything you need to know.
What is hypochlorous acid?
Hypochlorous acid is a naturally occurring substance produced by our white blood cells, which serves to eliminate harmful bacteria and irritants in our bodies, as explained by Dr. DeRosa. Essentially, it can be thought of as nature's disinfectant, employed to counteract inflammation and accelerate the body's innate healing processes.
In the realm of science, hypochlorous acid is synthesized by combining salt, water, vinegar, and electrolysis. The outcome is a formula that emulates the skin's intrinsic ability to combat bacteria and facilitate healing. When this formula is appropriately concentrated and incorporated into your preferred skincare and haircare products, it can provide a healing boost to your face and scalp whenever needed.
In more concentrated forms, hypochlorous acid can be found in common household cleaners like Clorox. It is utilized to disinfect surfaces, sterilize medical equipment, and, as King notes, has even demonstrated effectiveness in eliminating the coronavirus.
What advantages does the use of hypochlorous acid offer?
Hypochlorous acid possesses potent antibacterial, antiviral, and antifungal properties," Its effectiveness in addressing a range of skin issues, from cystic acne to sunburns, is attributed to these qualities.
In essence, hypochlorous acid serves as a versatile solution in skincare — there are few issues it can't address. It can even assist in the recovery of severe sunburns. Applying a hypochlorous acid spray, directly to your face or scalp can provide immediate relief and promote healing for sun-damaged skin.
Given that hypochlorous acid is naturally present in your body, products containing HOCl are suitable for daily use. Unlike prescription antibiotics, there's no risk of developing a resistance to it, and it won't lead to skin dryness like alcohol or benzoyl peroxide might.
Are there any potential drawbacks or hazards?
As per our experts, the use of products containing hypochlorous acid for treating various skin conditions is generally considered safe. This is contingent on the condition that these products are appropriately formulated and specifically designed for skin application.
Ginger King cautions, "When used undiluted, this substance can potentially cause chemical burns. The concentration required varies for different purposes. In skincare, it must be diluted to 100 parts per million." She emphasizes the importance of refraining from attempting to dilute hypochlorous acid independently or using products not explicitly meant for skin use (yes, that includes Clorox wipes). "Opt for products that are pre-diluted and come with usage instructions," she advises. "When properly formulated, you can use the product daily without any significant risk."
Nonetheless, our experts do recommend avoiding contact with your eyes and mouth when applying skincare products containing HOCl, as it is an acid.
Who Should Incorporate Hypochlorous Acid?
Hypochlorous acid offers benefits for individuals of all skin types. Its natural presence in our bodies already aids in combating bacteria and infections. For those with sensitive skin, there's no hesitation in using products containing hypochlorous acid, even if you have exceptionally delicate skin. Dr. DeRosa emphasizes that adding hypochlorous acid to your skincare routine can be particularly beneficial when addressing skin conditions like acne or eczema.
Special Considerations for Sensitive Skin:
Even for those with highly sensitive skin, it's essential to seek out fragrance-free hypochlorous acid products. For example, Curative Bay's Advanced Hypochlorous Acid Skin Spray offers pure hypochlorous acid without added fragrances. If any skin irritation occurs, it's more likely attributable to other ingredients, such as fragrance, as advised by dermatologists. This ensures a gentle and soothing experience for delicate skin types.
Using Hypochlorous Acid in Your Skincare Routine
Hypochlorous acid, a potent antibacterial ingredient, is commonly found in cleansers, serums, and creams. However, one of the most prevalent application methods is through sprays. After cleansing, she advises applying a thin layer of the spray across your face before proceeding with the rest of your skincare routine. Ensure to seal in all products with a moisturizer as the final step.
For additional benefits, suggests using products with hypochlorous acid to spot-treat acne, soothe sunburns, or even sanitize hands when needed. These products, safe for daily use, can provide an extra dose of hypochlorous acid to address common skin concerns like acne and eczema, promoting clean, clear, and well-hydrated skin.
