Hypochlorous Acid Spray for Aesthetics & Skin-Focused Routines
Skin-focused routines do not begin and end with the treatment itself. What happens around them matters too — from keeping skin clean and comfortable to choosing products that fit easily into an everyday routine.
BLOK Skin Defence Spray is a fine-mist 200ppm hypochlorous acid spray designed for straightforward skin hygiene. Made in the UK, it is pH neutral, alcohol free and fragrance free, with no sticky residue.
Why hypochlorous acid is being used in skincare
Hypochlorous acid — commonly shortened to HOCl — has become increasingly visible within modern skincare. Its appeal is simple: it can be delivered as a lightweight mist and incorporated into a routine without the heaviness of a traditional cream, cleanser or serum.
For aesthetics clients and anyone taking a more considered approach to skin hygiene, that makes HOCl an interesting addition to the skincare toolkit.
Where Skin Defence Spray fits
Skin Defence Spray is designed to be simple to use. Mist it directly onto the skin and allow it to air dry naturally.
There is no rinsing and no rubbing required, making it easy to use on the face or body and straightforward to carry as part of a daily skincare routine.
It is not intended to replace cleansing, good hygiene or professional aftercare advice. Instead, think of it as another practical skin-hygiene step that can sit alongside an existing routine.
Built for skin. Designed for real life.
The same qualities that make Skin Defence Spray useful around training, travel and everyday life also make it relevant to skin-focused environments.
