Leucillin Has A Brand New Look, With The Same Trusted Formula!

We’re excited to announce that Leucillin has had a complete rebrand! After 16 years on the market, helping provide relief for skin and supporting first aid across the animal world, Leucillin is stepping into its next chapter with a fresh new look. Leucillin is the still same brilliant formulation of HOCl that it has always been, with an updated look and feel.

You’ll start to see the new packaging appearing across the UK, before rolling out worldwide, making Leucillin easy to recognise wherever you find it.

The refreshed design features a brand-new Hypochlorous Acid (HOCl) molecule graphic, alongside clearer labelling across the entire range. From our handy 50ml dropper through to our 500ml bottle, the new labels have been designed to make it easier for customers to identify the product and understand what they are buying.

And, of course, we couldn’t let go of our signature ‘Leucillin purple’. The distinctive colour remains a key part of the new design, linking our exciting new look with the Leucillin that customers have trusted for more than a decade and a half.

Leucillin is stocked at every Pets at Home, Just for Pets and Jollyes, as well as online through Violet, VetUK and Amazon, plus many independent retailers, grooming salons and veterinary practices.

We truly hope all our Wholesalers, Retailers and end user customers love the look as much as we do!

Wish I Knew About This Fantastic Stuff Sooner

I originally bought it to clean my elderly cats chin that appears to have scabs on it. After using daily twice a day, the scabs have almost gone. I also use this to clean my cats and dogs ears and wipe under their eyes and for any itchy spots and it's brilliant. I can't praise it highly enough. Only wish I had found it sooner.

A must have in my opinion

I've used leucillin for many minor skin issues on our slightly prone to skin issues/allergies dog and wouldn't be without it. It's not a fix all but feel it's like a safe savlon/germoline equivalent for dogs. She feels zero discomfort at application and also easily discouraged from licking it. Useful for cleaning any sort of wound or as a first safe treatment of any skin irritation. Often it's all that's needed.

Leucillin is a fabulous product which no yard or indeed home should be without

I have tried all sorts of lotions and potions over the years for cuts, sores etc all I can say I wish I had known of this wonderful product sooner. I now make sure that we always have a bottle to hand.

Great antiseptic

I always have this with me on our dog walks. Great for if we have a cut or a thorn injury. At least I know I've done the best I can to keep the wound clean till I can get to my vet. Never leave home without it.

I find it so useful that I even carry a small bottle in my handbag

What I have found magic about Leucillin is that whenever you are not quite sure what to do or put on, I just give a squirt of Leucillin – if it’s a weepy eye, a smelly foot, a cut, a graze, a bite or some odd skin problem, they all have the same application.

We now use it as our 'go-to' solution

We have been using Leucillin for several months now and have been delighted with the results we have had. We now use it as our 'go-to' solution for any cuts, nicks and scrapes and have found it very useful in reducing harmful pathogens and swelling of these sorts of areas. The fact that it is totally safe to use around the eyes, mouth and other sensitive areas is also a big plus and helps set this product further apart from the previous sprays that we would use around the yard.

I found Leucillin extremely easy to use

My horse recently contracted ringworm with about ten different lesions appearing on his head and neck which seemed to be spreading at an alarming rate. I started to apply Leucillin twice a day to the affected areas and within a week all symptoms of ringworm had cleared up and disappeared. I found Leucillin extremely easy to use by simply spraying the affected areas and rubbing in using gloves. Subsequently I have used Leucillin on cuts and minor wounds on the horses and found it an extremely effective way to clean, keep clean and promote quick and easy recovery. A must have product to be kept in every stable and yard at all times.

Its a must for every first aid kit that's for sure!!

Having been involved with horses all my life and managed an Equestrian Retailing outlet for the past 25 years I have come across many products and can honestly say that I have never had anything quite like Leucillin before, It it totally amazing and so universal, it heals everything!!!!!, My ex racehorse had a nasty rope burn and within 24 hours the wound looked totally different, my niece's dog had a sore eye but with a few applications was just fine again.

I was very pleased and will definitely be using Leucillin again

I used the Leucillin on a small cut behind my horses ear - it had broken the skin and was slightly swollen but nothing very severe. I have to say the following day the cut had scabbed over really well and the small swelling had gone down.

Jackie Hooper

My friends with horses RAVE about it

I've been using it on me and my dog. Did a fab job on a spot (better than any spot cream) and have just nipped a small case of shingles in the bud with it too. Use it on the dog after a tick removal. Thank you Leucillin!

Sarah Dowding

I know its 100% safe

I use it for my beardies when they get nasty bites or scratches from each other. I'm a bit weary of using human antiseptics or anything with iodine in as they can't eat anything from the sea which is where iodine comes from and have found that Leucillin has no bad reaction and helps them recover a lot quicker without having to worry that the other one might lick/bite and ingest something harmful. I also use it to clean their food bowl so know its 100% safe for them.

The site recovered cleanly with no problem and the hair grew back quickly

Have used Leucillin on both my horse and my cat with very pleasing results. My horse had some very bad fly bites which caused a reaction. Leucillin seemed to calm the itch and helped the rubbed areas to recover quickly. My cat was in a fight and received a minor bite, which I regularly bathed with Leucillin (he allowed me to, unusually). The site recovered cleanly with no problem and the hair grew back quickly.

I sprayed his legs twice a day and it kept the mud fever away!

I have used leucillin on my horse for mud fever, He gets it every year on his back white legs. It clears in the summer but every winter it comes back. This last winter I sprayed his legs twice a day and it kept the mud fever away!

Abbi Rollins

The results are amazing!

My bulldog suffers from a skin condition, we don’t quite know what it is, we have tried many creams, sprays and shampoos. Nothing seemed to fully clear it up. We then found Leucillin, we have been using it now for 3-4 weeks and the result is amazing, the patches on his skin have dried up and the fur is starting to grow back.
