Hypochlorous Acid Mists Join the Conversation (2025)

Hypochlorous Acid (HOCl) in Skincare

Overview:
Hypochlorous acid (HOCl) is a weak acid naturally produced by white blood cells to fight infections and kill bacteria. It’s gaining popularity in skincare for its soothing and antimicrobial properties.

History and Use:

• Historically used as a disinfectant, developed in 1834.
• Employed in hospitals for wound care and even in veterinary medicine.

Skincare Benefits:

• Antimicrobial and anti-inflammatory, useful for conditions like acne and seborrheic dermatitis.
• Acts quickly to calm irritation and reduce redness.
• Gentle on sensitive skin, unlike harsher treatments like benzoyl peroxide.

Practical Uses:

• Can be used topically as sprays or mists.
• Effective for disinfecting personal items like makeup brushes and gym gear.
• Used in eye care for dry eyes and styes.

Considerations:

• May interfere with vitamin C and antioxidants; use them at different times (vitamin C in the morning, HOCl at night).
• Strong AHAs can disrupt its pH.
• Stability is a concern; it requires proper storage in opaque, stabilized packaging.

Conclusion:
HOCl is celebrated for its gentle, effective antimicrobial properties in skincare, though its efficacy depends on proper usage and storage.
