Why we standardised at 200 ppm
Hypochlorous acid products span a wide concentration range. Lower solutions are comfortable but thin in character. Higher solutions can be difficult to use every day on the whole face.
200 ppm is our chosen midpoint: enough to feel like a deliberate step in a routine, restrained enough to use morning, evening and after training without hesitation.
Concentration only matters if it survives the bottle. HOCl is light sensitive, so STRATA ships in an opaque container with a fine-mist pump that limits air exchange.
