💧 What Is Leucillin?

Every animal lover knows how quickly a small cut, sore patch, or irritated ear can turn into something more serious. That’s where Leucillin comes in — a must-have natural antiseptic spray trusted by pet owners, groomers, and even equine professionals across the UK.

Leucillin is an antibacterial, antifungal, and antiviral skin and wound care solution that’s completely safe for all animals — from dogs and cats to horses, rabbits, birds, and reptiles.

Its active ingredient is Hypochlorous Acid (HOCl) — a natural compound produced by the body’s white blood cells to fight infection and inflammation. Leucillin simply captures this natural defence in a stable, bottled form that you can use at home.

That means:

✅ 100% non-toxic
✅ Fragrance-free and alcohol-free
✅ Safe for skin, eyes, ears, and sensitive areas
✅ Works with the body’s natural healing process

It’s one of those products that quietly becomes an essential part of your pet care routine — because it just works.

🌿 Why Choose Leucillin Over Conventional Antiseptics?

Many traditional antiseptics contain alcohol, iodine, or chlorhexidine — ingredients that can sting, dry the skin, or cause irritation. Leucillin is different.

It’s completely safe if licked, gentle on skin and eyes, and suitable for even the most sensitive animals. Because it mimics the body’s natural chemistry, there’s no burning sensation or risk of overuse.

For multi-pet households, horse owners, or anyone who prefers a natural approach, Leucillin replaces a whole cupboard full of harsh sprays and wipes with a single, safe bottle.

🩹 What Leucillin Can Be Used For

Natural antiseptic for animals and humans

🐾 How Leucillin Helped Keana

When I first started stocking Leucillin, I already knew it was something special — but I became truly convinced when my Rottweiler, Keana, developed an irritated eye.

She kept pawing at it and holding it shut, clearly uncomfortable. I checked for debris but couldn’t see anything obvious. Instead of reaching for medicated drops or chemicals, I tried Leucillin.

I dropped a few drops directly into the eye (it doesn’t sting — at all!), and by the next day her eye was noticeably better. Within two days, the irritation was gone. No redness, no watering, no fuss — just one very happy girl again. ❤️

That was my “aha” moment. If it could be gentle enough for eyes yet powerful enough to clear irritation, I knew it deserved a spot in every animal first-aid kit.

⚡ How It Works

Leucillin works by using Hypochlorous Acid to mimic the body’s natural immune response. When applied to the skin, it destroys bacteria, fungi, and viruses by breaking down their cell walls — without harming healthy tissue.

In short:

It kills up to 99.99999% of germs
It’s pH-balanced for skin health
It helps speed up natural healing

Unlike alcohol or iodine-based antiseptics, it doesn’t dry the skin or disrupt the microbiome — so healing happens faster and more comfortably.
