The ingredient narratives reshaping clean beauty.
Hypochlorous Acid (HOCl)
The unlikely crossover ingredient of 2025: a molecule produced by the immune system's white blood cells, migrated from wound care and post-procedural disinfection into mainstream clean skincare. Kills bacteria, viruses, and fungi without disrupting the barrier — non-cytotoxic, non-sensitizing, safe even for babies and post-procedure skin. Tower 28's SOS Daily Rescue Facial Spray made it viral.
- antibacterial without barrier disruption
- non-sensitizing across all skin types
- safe post-procedure and on compromised skin
- face mists
- post-procedure sprays
- acne-prone and sensitive-skin rescue
Effective at 0.01–0.02%. Free of synthetic preservatives, parabens, alcohol, and fragrance.
Inherently unstable — poorly manufactured HOCl degrades rapidly. Quality-tier divide is wide; favor brands with documented stability data.
Strongly positive — proof point that 'gentle' and 'effective' are not opposites.
