What Is Hypochlorous Acid?

Hypochlorous acid (HOCl) is a naturally occurring antibacterial and oxidizing agent produced naturally produced in the cells of all mammals and is a part of the body’s immune response. The neutrophils, eosinophils, mononuclear phagocytes, and B lymphocytes (parts of the immune system and white blood cells) produce hypochlorous acid, the first line of defense against infections, injury, and irritation. It promotes wound healing and manages inflammatory skin conditions (such as seborrheic and atopic dermatitis) and diabetic ulcers.

French chemist Antoine Jérôme Balard discovered hypochlorous acid in 1834 and used it for wound care. It was widely used during both World Wars for wound healing.

Topical use of hypochlorous acid has therapeutic, antimicrobial, and immunomodulatory effects on the skin. Let’s understand how it may benefit your skin.

Benefits Of Hypochlorous Acid For Skin

1. Promotes Wound Healing

Clinical studies have shown that HOCl acts as an effective agent to reduce bacterial count in open wounds and promote healing. This disinfectant is active against bacteria like S.aureus, A. baumannii, and P. aeruginosa, preventing the further degradation of skin tissues in wounds. It also eliminates wound odor and is not painful.

2. Can Inactivate Viruses

Hypochlorous acid can inactivate several species of viruses, including the coronaviruses. This antiviral ingredient destroys the viruses by chlorination. It forms chloramines and nitrogen-centered radicals, breaking the DNA in the virus (both single and double-stranded) and making it harmless. That is why it is commonly used in sanitizers and disinfectant sprays.

3. Reduces Inflammation

Hypochlorous acid can decrease skin inflammation and soothe conditions like eczema and atopic dermatitis. It can relieve itching and skin discomfort associated with these conditions. It eliminates S. aureus bacteria from the skin. These bacteria produce superantigens that stimulate the T cells, causing itching and rashes.

4. Prevents Acne

S. aureus also aggravates acne. Hence, applying hypochlorous acid can reduce bacterial infection, calm irritation, redness, and inflammation of the acne lesions. It may also prevent further breakouts. That is why hypochlorous acid is commonly used in acne creams and lotions.

Kimberlee, a YouTuber, shared her experience of using hypochlorous acid to treat her acne and was amazed with the results. She said, “My skin’s looking really good. I don’t have as much giant breakouts as I used to (i).”

5. Promotes Post-Procedure Healing

Hypochlorous acid can promote post-procedure healing from the skin and cosmetic procedures. It has anti-inflammatory properties and can help reduce itching, redness, swelling, and irritation related to cosmetic skin procedures.

Hypochlorous acid is popularly used in medical settings by doctors for cleaning surgery sites and post-surgery healing. However, it has slowly made its way into the consumer market and is available in various forms.

US Food and Drug Administration (FDA) approves the use of hypochlorous acid for topical wound management (5).
