HYPO21 is a British-made, medically registered hypochlorous (HOCl) skin spray — a pure, bioidentical mist engineered to mirror the molecule your own immune system releases to defend, calm and restore skin. Free from alcohol, fragrance and preservatives, its ultra-fine mist soothes the look of redness and supports skin prone to breakouts, rosacea, eczema and sensitivity. Skintique is an authorised UK stockist.
Not sure where a hypochlorous mist fits alongside your actives? Our Academy entry on hypochlorous acid covers what the molecule is, how it is made and why it is formulated at such low concentrations — helpful if you are deciding when in the day to use it. If you are building a gentler routine around it, the sensitive skin guide explains which textures and formats reactive skin tends to tolerate best.
What is HYPO21 Purifying Skin Spray and who is it for?
HYPO21 is a 100ml hypochlorous acid (HOCl) spray that purifies and calms the look of redness-prone and blemish-prone skin. It suits anyone whose skin flares after workouts, shaving, masks or in-clinic treatments. As a single-ingredient mist, it slots into any routine without clashing with your actives.
How do I use HYPO21 in my routine?
Hold the bottle 15 to 20cm away, mist over clean skin and let it air-dry — no rinsing or wiping. Use it morning and night before serums, and re-spray after the gym or a sweaty commute. On the days you use retinol or acids, a mist beforehand leaves skin feeling calmer.
What does hypochlorous acid do for my skin?
The hypochlorous acid in HYPO21 is the same molecule your own immune cells produce, so it purifies the skin surface while staying gentle on reactive, redness-prone complexions. It settles the look of post-blemish redness and keeps the surface fresh without stripping. Unlike alcohol toners, HYPO21 won't leave skin tight or flaky.
Can I use HYPO21 around my eyes, on my body or after treatments?
Yes — it's fragrance-free and gentle enough for the eye area, scalp, body and freshly treated skin after microneedling or shaving. Spray it directly, or onto a cotton pad for targeted areas. Keep the bottle upright and use within the shelf life printed on the base, since HOCl is a fresh, active formula.
How should I store it and does it expire?
Store HYPO21 somewhere cool and out of direct sunlight, and finish it within 12 months of opening so the hypochlorous acid stays effective. The 100ml size is cabin-bag friendly for travel and the gym. Order before 2pm from us, an authorised UK stockist, for same-day dispatch and free tracked delivery on orders over £50.

HYPO21 is an ultra-purified, medically registered hypochlorous (HOCl) skin spray, made in Britain. HOCl is the same molecule your immune system naturally produces to defend skin and manage inflammation — HYPO21 is engineered to preserve that biological behaviour, not simply copy its chemistry, so your skin recognises and responds to it.
What makes it different
Most hypochlorous sprays are chemically stabilised for shelf life and made mainly to disinfect. HYPO21 is made differently: a unique purification and filtration process keeps it structurally aligned with naturally occurring HOCl. It is a deliberately minimal formulation — no alcohol, no fragrance, no preservatives and no unnecessary stabilisers — gentle enough for the most reactive skin.
Who it's for
Sensitive, reactive and easily irritated skin
Breakout-prone, congested and blemish-prone complexions
Rosacea-prone and redness-prone skin
Skin recovering after aesthetic treatments
All ages, including very sensitive skin
How to use
Mist generously over clean skin morning and night, or any time skin needs calming. Let it absorb in 30–60 seconds — no rinsing and no residue. Use before your serum and moisturiser, after exercise, or to refresh through the day.

I was able to try it for a week, and all I can say is that it's practically miraculous. Sadly, I have a disability, and by accident, the bottle wasn't sealed properly and fell on the carpet, spilling all the serum. Obviously, I can't afford to buy another one right now. Absolutely recommended.
