HYPO21 Skincare FAQs

Discover HYPO21 and its innovative approach to hypochlorous acid skincare. From sensitive and irritated skin to everyday cleansing and specialist care, explore our FAQs to learn how HYPO21’s minimalist HOCl formulas can support your skin.
What is HYPO21? Plus

HYPO21 is a British-made specialist skincare brand centred around ultra-purified hypochlorous acid (HOCl). Its medically registered formula is engineered to closely align with naturally occurring hypochlorous acid and work in harmony with the skin’s natural defence and recovery processes.

What is hypochlorous acid in skincare? Plus

Hypochlorous acid, or HOCl, is a molecule naturally produced by white blood cells as part of the body’s immune response. HYPO21 uses a biologically aligned form of HOCl developed to remain skin-compatible while supporting the skin's natural defence and recovery mechanisms.

Is HYPO21 suitable for sensitive or irritated skin? Plus

HYPO21's minimalist formulation is free from alcohol, preservatives and unnecessary stabilisers. This makes the Purifying Skin Spray particularly relevant for routines focused on sensitive, irritated or compromised skin where a simple, gentle approach is preferred.

What can HYPO21 Purifying Skin Spray be used for? Plus

HYPO21 Purifying Skin Spray provides a simple way to incorporate hypochlorous acid into an everyday skincare routine. Its gentle approach makes it particularly suited to skin that feels sensitive, stressed or prone to irritation, while HYPO21's wider range extends its technology into specialist intimate, baby and oral care.

What makes HYPO21 different from other hypochlorous sprays? Plus

HYPO21 focuses on preserving the biological behaviour of hypochlorous acid rather than simply using HOCl as a cleansing ingredient. The brand uses a specialist purification and filtration process designed to maintain skin compatibility without unnecessary chemical interference, and describes its formula as medically registered in the UK.
