What Is Hypochlorous Acid?
Hypochlorous acid (HOCl) is a molecule naturally produced by your body’s immune system to help defend against bacteria and irritation.
In skincare, hypochlorous acid is loved for its ability to help calm redness, refresh the skin, and support a healthy skin barrier - all while being gentle enough for sensitive and breakout-prone skin.

Why Is Hypochlorous Acid Used in Skincare?
HOCl works by helping neutralise impurities and supporting the skin after stressors like sweat, workouts, heat, and environmental buildup.
Unlike harsher active ingredients, hypochlorous acid is lightweight, non-stripping, and suitable for everyday use.
