Ultra-pure HOCl for clean, balanced, healthy-feeling skin

Everyday skin defence, made simple

Full Guard is an ultra-pure 95% hypochlorous acid (HOCl) spray — a light, fragrance-free mist that leaves skin feeling clean and fresh in seconds. It was originally developed for professional combat-sport athletes who are fussy about looking after their skin, and it's now for everyone who wants a simpler way to stay fresh between washes. One quick spritz, let it air-dry, done.

"Skin defence" sounds dramatic, but it really isn't. It's not about one heroic product — it's about a small, gentle habit you'll actually keep. Your skin is the hardest-working surface you own: it takes the sweat, the friction, the long days, the gym-to-work dashes when a shower isn't an option. Looking after it shouldn't mean scrubbing it raw with the harshest thing on the shelf. Full Guard is the opposite of that — a kind, no-drama everyday step that keeps your skin feeling clean without stripping it.

What is hypochlorous acid (HOCl)?

Hypochlorous acid is one of the simplest molecules in the body — and yes, your body already makes it. It's produced naturally as part of normal biology, which is a big reason a well-made HOCl mist tends to sit so comfortably on skin. It's water-thin, has no added fragrance, and dries without any sticky residue.

What makes Full Guard different from the dozens of hypochlorous sprays that have appeared lately is purity and consistency. Plenty of HOCl sprays are watered down and weakly made. Full Guard is ultra-pure 95% HOCl, produced in the UK to a recognised cosmetic standard, so what's in the bottle is exactly what it says — nothing padded out, nothing perfumed. If you want the plain-English chemistry, we've written it up in how hypochlorous acid works and how your body makes HOCl.

Why your skin needs a little looking after

If you train, you already know your skin gets put through it. A hard session leaves it warm, damp and a bit scuffed from all that friction and contact. Then it sits there — sealed under a wet rashguard, marinating on the drive home — until you finally get to a shower. Outside of sport it's much the same story: a sweaty commute, a long shift, hours behind a face covering or a helmet, travel days where a proper wash is hours away.

None of that is dramatic on its own, but it adds up, and the usual response — blitzing your skin with the harshest, most heavily fragranced product you can find — tends to make things worse, not better. Strip your skin too hard, too often, and it gets dry, tight and irritated. Real everyday skin defence is gentler than that: keep your skin clean and comfortable, don't overdo it, and use something kind enough to reach for every single day. We get into the why in harsh cleansers and your skin barrier and skin barrier basics for athletes.

What everyday skin defence really means

Let's be honest about the phrase, because it gets thrown around a lot. Everyday skin defence isn't a magic force field and it isn't a one-off rescue. It's the unglamorous, genuinely useful stuff: keeping your skin clean and comfortable, not letting sweat and grime sit on it for hours, and using products gentle enough that you'll actually keep the habit. The people with the best skin in any gym usually aren't the ones with the most aggressive routine — they're the ones with the most consistent one.

That's the whole design brief behind Full Guard. It's deliberately easy: one bottle, one quick mist, no fuss, nothing that stings or stinks. Make it a reflex — off the mat, before the drive home, last thing before bed — and your skin gets looked after every single day without you having to think about it. Defence, in other words, is really just a good habit you'll keep.

What you can use Full Guard for

One of the best things about a fragrance-free HOCl mist is how many gaps it quietly fills. Here are the everyday uses people reach for it most.

After training — the mat-side freshen-up

This is where Full Guard earns its place. The moment you step off the mat or out of the ring, mist it over the skin that took contact — hands, forearms, neck, shoulders, feet — and let it air-dry while you sort your kit. It's not sticky, it doesn't reek of fragrance in a shared changing room, and it travels in any gym bag. It's the easy first step until you can get to a proper shower. There's a full routine in the mat-side ritual and the two-step post-training routine.

On your face

Because it's fragrance-free and doesn't strip, plenty of people use Full Guard as a simple facial mist — after a session, after a helmet or a mask, or just as an easy step morning and night. Mist over clean skin with your eyes closed and let it air-dry; it won't clash with the rest of your routine. More in hypochlorous acid for your face and layering HOCl with skincare.

Body, feet and the bits soap forgets

The same logic works below the neck: a quick mist over the chest, back, underarms and feet keeps things feeling fresh between washes — handy when you're going straight from training to work. It's gentle enough for areas that don't love strong soaps, and there's a dedicated guide for feet and footwear freshness in HOCl for feet and footwear.

Travel and busy days

Water-thin, leak-friendly and fragrance-free, Full Guard lives happily in a handbag, a desk drawer or a glovebox. On a long flight, a festival, or a packed day with no sink in sight, it's the freshen-up that takes the edge off. See travel skin hygiene with an HOCl mist.

Sensitive, easily-irritated skin

If your skin reacts to everything, the appeal of a no-fragrance, no-alcohol mist is obvious. It's a low-drama way to feel clean without the sting and tightness that harsher products can leave behind. More in HOCl for reactive skin and why it doesn't sting.

For coaches, gyms and the whole family

Because it's gentle and fragrance-free, Full Guard isn't only a personal bottle. Coaches and academy owners keep one by the mats as an easy, no-nonsense option for members; parents like that there's no harsh smell or sting for kids coming off the mats; and plenty of households end up sharing a bottle simply because it's handy to have around. If you run a gym, our coach's guide to a gym hygiene policy is a good companion read.

Why Full Guard stands out

• Ultra-pure 95% HOCl — high-purity hypochlorous acid, not a watered-down version.
• Fragrance-free and alcohol-free — fewer additives, so less to irritate skin or bother training partners.
• No sting, no stripping — gentle enough to use every day, even on the face.
• Fast-drying and non-sticky — a fine mist that dries in a minute or two and won't ruin your kit.
• UK-made to a recognised cosmetic standard — with a long shelf life when stored cool and out of direct sun.
• Developed with athletes — built for people whose skin takes a daily beating, now for everyone.

If you're weighing up sprays, our independent buyer's guide on how to choose the best hypochlorous acid spray walks through purity, pH, packaging and additives — and Full Guard was built to exactly those standards.

How to use it

Hold the bottle a few inches from clean skin, mist generously over the areas that need it, and let it air-dry for a minute — don't wipe it straight off. Use it daily, especially right after training, and any time you want to feel fresh between washes. A little goes a long way, so even with daily use a bottle lasts a good while. It's a freshen-up for the gaps, not a replacement for a proper wash when you can get one. There's a fuller how-to in how to use a hypochlorous acid spray.

Full Guard vs the harsh stuff

The instinct in combat sports is to go nuclear — the strongest, most heavily fragranced bar you can find, used like you've got a grudge against your own skin. The trouble is that the harshest products don't discriminate; they strip the good with the bad and leave skin dry, tight and unhappy. Full Guard takes the opposite approach: a gentle, fragrance-free mist you'll happily use every day, because consistency beats intensity. The best routine is the one you actually keep up.

Searching for Defence Soap in the UK? The bar you can actually buy here isn't the medicated US version, and it isn't cheap. Our take — a no-sting, UK-made HOCl spray paired with a sensibly priced athlete soap — is built around the same idea: clean, fresh skin without the drama.

If you have a specific skin concern, check with a pharmacist, GP or dermatologist — it's a cosmetic, not a treatment. See is hypochlorous acid safe?

Can I use it on my face? Yes — many people use it as a simple facial mist. Eyes closed, mist, let it air-dry.

Is it the same as hand sanitiser? No. Full Guard is a cosmetic skin-freshening spray — not a hand sanitiser, and not a substitute for washing your hands with soap and water.
