What Is Hypochlorous Acid Used For On Skin?

Hypochlorous acid (HOCl) is a weak acid that forms when chlorine dissolves in water. It is naturally produced by white blood cells in all mammals as part of the body's immune response. In its purest form, hypochlorous acid is a powerful yet gentle substance that has a variety of applications, particularly in skincare.

The Science Behind Hypochlorous Acid

Chemical Composition and Properties

Hypochlorous acid is an oxyacid of chlorine, with the chemical formula HOCl. It is known for its potent antimicrobial properties, capable of killing bacteria, viruses, and fungi. Despite its strength, it is non-irritating to skin and eyes, making it an ideal component in various skincare products.

Uses of Hypochlorous Acid on Skin

Antimicrobial Properties

One of the primary uses of hypochlorous acid on skin is its antimicrobial action. It is effective against a broad spectrum of pathogens, including bacteria, viruses, and fungi. This makes it invaluable in wound care, as it can prevent infections and promote faster healing.

Acne Treatment

Hypochlorous acid is also beneficial in treating acne. Its antimicrobial properties help reduce the bacteria that cause acne, while its anti-inflammatory effects reduce redness and swelling. Unlike many harsh acne treatments, hypochlorous acid does not dry out the skin, making it suitable for all skin types.
