What Is Hypochlorous Acid? The Science Behind HOCl
What Is Hypochlorous Acid?
Hypochlorous acid (HOCl) is a naturally occurring molecule produced by your white blood cells as part of your immune response. It's one of the most powerful — yet gentle — antimicrobial agents found in nature.
When your body detects harmful bacteria or irritants, neutrophils (a type of white blood cell) generate HOCl to neutralize threats. This same molecule has now been harnessed for topical skincare use.
How Does HOCl Work on Skin?
Unlike harsh chemical cleansers that strip your skin's natural barrier, hypochlorous acid works with your biology. It:
Why Is Everyone Talking About It Now?
While HOCl has been used in wound care and medical settings for decades, recent advances in stabilization technology have made it available in consumer-friendly formats like mists and sprays.

Frequently Asked Questions
What is hypochlorous acid (HOCl)?
Hypochlorous acid is a gentle molecule your white blood cells naturally produce to keep skin clean and balanced. IRONPUR™ delivers a stabilized, skin-pH version in a fine mist with only 3 ingredients: water, salt, and HOCl.
Is hypochlorous acid safe for daily use on the face?
Yes. HOCl is non-irritating, fragrance-free, and alcohol-free, making it safe for daily use on the face, around the eyes, and on sensitive or post-procedure skin.
How is HOCl different from bleach?
Bleach (sodium hypochlorite) is a harsh, high-pH industrial chemical. Hypochlorous acid is a different molecule entirely — pH-balanced for skin, non-toxic, and bioidentical to what your body already produces.
Can I use hypochlorous acid spray with other skincare?
Yes. HOCl works well as a pre-cleanse mist, alcohol-free toner replacement, or refresh between products. Use it before serums and moisturizers, or any time you want to reset skin without stripping it.
