In the world of skincare, it’s not every day that a product comes along that is both powerful and
gentle. But hypochlorous acid (HOCl) is exactly that. It is a naturally occurring compound that
has made its way from medical settings into our daily skincare routines. So what is it, what does
it do, and is it safe for your family’s skin? Let’s break it down.
What Is Hypochlorous Acid?
Hypochlorous acid is a substance your body already knows well. It’s produced naturally by
white blood cells as part of the immune response. When your body detects invaders like bacteria
or viruses, it uses HOCl to destroy them. Quickly and effectively.
Scientists have found a way to replicate this powerful molecule in labs, creating a stable form
that can be bottled and used in everything from wound care sprays to facial mists and even
cleansers.
Why Hypochlorous Acid is a Skincare Superstar
Despite its scary-sounding name, hypochlorous acid is incredibly gentle. Here's why it's popping
up in facial sprays, acne treatments, and even baby skincare lines:
Antibacterial & Antiviral. HOCl eliminates bacteria and viruses on contact; without disrupting the skin’s natural barrier or microbiome. It’s like hand sanitizer without the sting or dryness.
Reduces Redness & Inflammation. Because it’s anti-inflammatory, hypochlorous acid is especially helpful for conditions like eczema, rosacea, and acne. It soothes the skin while cleaning it, making it ideal for sensitive or reactive skin types.
Promotes Healing. HOCl helps support wound healing by keeping the area clean and infection-free. It’s been used in hospital settings for years to treat burns, surgical wounds, and diabetic ulcers.
Safe for Kids and Babies. Its gentle profile means it’s often used on baby skin to treat rashes, bug bites, and scrapes. Unlike many harsh antiseptics, HOCl doesn’t burn or irritate; even on delicate skin.
How to Use Hypochlorous Acid in Your Routine
Most hypochlorous acid products come as a spray, mist, or cleanser and can be used:
After cleansing to calm skin and prep for moisturizer
On acne-prone areas to reduce bacteria and inflammation
On cuts, scrapes, or bug bites as a soothing antiseptic
On sensitive baby skin (diaper rashes, minor irritations)
As a post-sun spray to soothe mild sunburn
A little goes a long way! Just mist and let it dry. No need to rinse.
Is It Safe?
Yes! hypochlorous acid is non-toxic and non-irritating, even around the eyes or broken skin.
What to Look For in a Product
Not all HOCl sprays are created equal. When shopping, look for:
Purity – HOCl as the main ingredient, without alcohol or added fragrance
pH-Balanced – around 4.5–6.5 is best for skin compatibility
Stable formula – ideally with a short shelf life (because that means fewer additives)
Active Skin Repair is a popular and highly regarded skincare product—especially for babies,
kids, athletes, and anyone with sensitive or injury-prone skin. It is a medical-grade, hypochlorous
acid (HOCl).
CLN is another popular brand and one we carry in office. It is a clinically tested skin cleanser
designed to gently but effectively cleanse compromised or sensitive skin. Unlike typical soaps or
body washes, CLN is specifically formulated to help reduce the risk of infection, calm
inflammation, and support the skin barrier; all without irritating or drying out the skin.
CLN contains sodium hypochlorite (a very diluted, safe form of bleach) that mimics the action of
dilute bleach baths—a long-standing dermatology treatment used to reduce Staphylococcus
aureus and other bacteria. While sodium hypochlorite is not HOCl, they are closely related and
have similar anti-inflammatory and antibacterial benefits.
Hypochlorous acid is a rare gem in skincare: science-backed, dermatologist-loved, and gentle
enough for even the tiniest faces. Whether you're dealing with breakouts, razor burn, or toddler
scrapes, it’s a multitasking must-have that truly earns its place on the bathroom shelf.
