    I’ve used Enzyme Defense since it was Virus Stop. My children, friends and grandchildren now keep it on hand also. Boosts your immune and keeps viruses at bay. Love it.

THE SCIENCE

What is Hypochlorous Acid (HOCl)?

Hypochlorous acid (HOCl) is a molecule naturally produced by white blood cells as part of the body’s innate immune response. When the skin encounters irritation, microbial exposure, or environmental stress, neutrophils generate HOCl to help neutralize unwanted pathogens and support tissue balance.

HOCl is both powerful and highly selective — rapidly targeting bacteria, viruses, and fungi while remaining non-cytotoxic to healthy skin cells. This unique combination of antimicrobial strength and tissue compatibility makes it fundamentally different from traditional antiseptics.

Curativa Bay formulates stabilized, high-purity HOCl designed to mirror the molecule your body produces — without alcohol, antibiotics, fragrances, or harsh chemical additives.

This is immune science, thoughtfully applied to everyday care.
