Hypochlorous Acid 101: What Is HOCl and Why Is It Used in Skincare?
Hypochlorous acid isn’t a new ingredient—it’s one your body has been using since before you were born. Here’s what it actually is, how it works, and why not every bottle of it is the same.
Your body already makes this
Hypochlorous acid (HOCl) is a molecule your white blood cells produce naturally, every time your body fights off infection or heals a wound. It’s part of your immune system’s first line of defence—gentle enough to work inside your own body, yet effective at clearing bacteria and calming inflammation.
Lumi Derma is that same molecule, made in a lab and bottled for your skin. We’re not introducing something foreign—we’re giving your skin more of what it already knows how to use.
Why it shows up in skincare
In practice, a well-formulated HOCl solution can help calm redness and irritation without stripping the skin barrier, support clearer-looking skin without the sting of many traditional treatments, and fit after cleansing—before serums and moisturiser—for sensitive, reactive, or everyday skin.
