What Is Hypochlorous Acid? The Science Behind Our Skin-Safe Super Ingredient

Learn how hypochlorous acid (HOCl) works, why your body already makes it, and how our non-toxic, fragrance-free spray and serum support skin healing without hormone-disrupting chemicals or allergens.

If you’ve been browsing our site or checking out our products, you’ve likely noticed one ingredient at the heart of everything we do: hypochlorous acid (HOCl).

But what exactly is HOCl—and why are doctors, podiatrists, dermatologists, and wellness experts so excited about it?

Let’s break it down.

Your Body Already Makes It

Hypochlorous acid is a molecule your immune system naturally produces to fight infection and reduce inflammation. When your white blood cells detect harmful bacteria or injury, they generate HOCl to help neutralize invaders, calm inflammation, and support healing.

We’ve taken that same powerful molecule and stabilized it for safe, everyday use in our Lighthouse Daily Defense Spray and Repair & Restore Serum—giving your skin a clean, effective way to protect and repair itself, just as nature intended.

How HOCl Works on Your Skin

Hypochlorous acid works in three key ways:

1. Antimicrobial – It kills harmful bacteria, viruses, and fungi without harming healthy tissue.

2. Anti-inflammatory – It helps calm redness, irritation, and flare-ups by signaling your body to reduce inflammation.

3. Wound-healing support – It promotes a healthy environment for skin to repair itself naturally.

   
   

Unlike harsh disinfectants or drying skincare products, HOCl is gentle and non-toxic, making it safe for even the most sensitive skin types.

Safe, Clean, and Free from Harsh Chemicals

We created our products with safety in mind. Our HOCl spray and serum contain:

• No hormone-disrupting chemicals

• No fragrances or dyes

• No parabens, alcohol, or preservatives

• No known allergens or irritating ingredients

• 
  

Because hypochlorous acid is biocompatible, the risk of allergic reaction is extremely low. It’s even safe to use around your eyes, on broken skin, or on children and pets.

A Smarter, Simpler Way to Care for Skin

Hypochlorous acid has been used in hospitals and wound care centers for years—but now you can use it every day at home.

Whether you're dealing with:

• Irritated skin

• Dry, cracked heels

• Redness and flare-ups

• Foot odor or fungal infections

• Minor cuts, scrapes, or sunburn

…our hypochlorous acid-powered products deliver science-backed care without the chemical overload.
