The science behind BLOK.
Your immune system naturally produces hypochlorous acid (HOCl) as part of its defence response. Researchers have studied its antimicrobial activity and effects on inflammation.
BLOK brings HOCl into everyday skincare: a gentle mist to soothe and refresh skin, without alcohol or fragrance.
Explore the HOCl science ↗Research & formulation
These publications examine HOCl in different formulations and settings, including laboratory and animal studies. They explain the ingredient science; they are not clinical trials of BLOK’s finished spray.
How to use
Spray onto your skin and allow to air-dry. Use morning, night or when your skin needs a refresh. Follow the directions on your bottle.
