Frequently asked questions
What is HYPO21 Purifying Skin Spray and who is it for?
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?
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?
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?
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?
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.
