Primocyn Eye Cleanser contains hypochlorous acid (HOCl) which has been proven to be safe in over five million users to date. HOCl at the concentration levels found in Primocyn Eye Cleanser can be used safely around eyes, ears, nose, and mouth.

What is hypochlorous acid (HOCl)?

HOCl is a compound that is produced naturally by the immune system, particularly neutrophils, to eradicate microorganisms.1

Benefits of HOCl
Stabilized hypochlorous acid (HOCl) helps reduce itch, inflammation and pain. It is also a powerful antimicrobial that kills skin pathogens associated with blepharitis, MGD, demodex and dry eye.

Who will HOCl help and what are the benefits?

HOCl has several specific properties that are beneficial for various skin conditions including those around eyelids and eyelashes. These include:

  • Potent antimicrobial
  • Reduction of pain and itch
  • Reduction of inflammation
  • Breaks down biofilm formed by S. aureus
Blepharitis Blepharitis
Demodex Demodex
Dry Eye Dry Eye

Effective Against Yellow Dust

Originating in the deserts of Northern China and Mongolia, "Hwang Sa" or Yellow Dust is whisked into the atmosphere by strong winds and carried to the Korean Peninsula via the jet stream. Other than reduced visibility, when the dust arrives it bring along industrial pollutants (like pesticides), viruses, fungi, bacteria and even heavy metals, none of which are good for your skin, eyes or respiratory health.

But with Primocyn Eau Divine it kills ALL bacteria, viruses, fungi, and molds in 30 seconds or less, helps clean and clear dust pollutants from your eyes, mouth, throat and sinuses. Helps moisturize dry eyes, relieves redness and itching and helps prevent glaucoma and cataract formation

Not all HOCl solutions are created equal

The positive effects of HOCl on the human body, both inside and out, have been studied and Recognized by medical scientists worldwide for over 100 years.

Today, Hypochlorous acid is bottled in a stabilized form so that you have a weapon to use against The countless environmental aggressors that threaten the health of your skin.

Don’t be fooled by others who claim to have superior HOCl solutions. Primocyn’s original HOCl formulas have been continuously improved over time and have set the standard of quality, stability and efficacy.

Reduction in Pain and Itch

Case Study #1

Open-Label Study

Study Design
  • Open-label, single-arm study over 7 days
  • HOCl rapidly reduces pruritus in mild-to-moderate atopic dermatitis (AD)
    • 50% of patients experienced a reduction by Day 1
    • 85% of patients experienced a reduction by Day 3
Percent of patients with improvement in pruritus
Percent of patients with improvement in pruritus

Case Study #2

Randomized, Blinded, Controlled Study

Study Design
  • 72-hour study
  • Treated group (n=19): HOCl BID
  • Untreated group (n=10): No treatment
  • Mean pruritus VAS scores between treated and untreated group were significantly different between baseline and 72 hours post application
Percent mean change in pruritus VAS

Anti-Inflammatory Activity

HOCl for Inhibition of Mast Cell Degranulation

  • Prevents allergen- and calcium-induced mast cell degranulation for up to 8 hours after a single exposure in-vitro
  • Reduces wound inflammation that inhibits healing
  • Stabilizes the mast cell membrane to inhibit the cell machinery for granule secretion, while not altering the signal transduction pathways or calcium mobilization
  • Inhibits degranulation stimulated by antigen or calcium ionophore
HOCI inhibition of mast cell degranulation stimulated by antigen or calcium lonophore

*A23187 + PMA is a calcium ionophore; †b-hexosaminidase is a marker of IgE-antigen-induced mast cell degranulation.

Breaks Down Bacterial Biofilm

Biofilm formation is recognized as a serious problem in chronic wound infections. Biofilm characteristics include

  • Complex structure of microorganisms that generate a protective shell, allowing bacteria to collect and proliferate
  • Most microorganisms that form biofilms found growing in microbial infection
  • Adheres to chronic wounds, makes phagocytosis difficult, and increases resistance to antibiotics
  • Inhibits degranulation stimulated by antigen or calcium ionophore

HOCl has antibiofilm activity and actively breaks down biofilm and kills microorganisms within the biofilm.

Corresponding microbicidal activity: 1/64 and lower dilutions of HOCl demonstrated zero colony-forming units of S. aureus

Increases Oxygenation

  • Provides higher levels of oxygen at a wound site after application
  • Elevated blood and oxygen flow increases wound-healing nutrients

Assists Wound Healing

Wound healing involves a complex sequence of events. Fibroblasts are the primary synthetic cells in the repair process of most structural proteins used during tissue reconstruction.

At lower concentrations, the percentage of fibroblast migration exceeded that of the control at 24 hours.

Although fibroblasts have a critical role in wound healing, their proliferation highly relates to keratinocyte proliferation and mediators secreted from keratinocytes.

Similar results were obtained for keratinocyte migration: At lower HOCl concentrations, the percentage of keratinocyte migration exceeded that of the control at 24 hours
