FAQs

What is Hypochlorous Acid?

Hypochlorous acid (also referred to as HOCl) is a weak acid that has a low pH and is naturally produced as part of our immune system during phagocytosis. When neutrophils encounter bacteria or other pathogens, the neutrophils engulf it, generate HOCl and instantly destroy the microorganism. This process is called the “oxidative burst”. During the activation of neutrophils, ‘respiratory bursts’ generate hydrogen peroxide (H2O2) and the activated granule enzyme myeloperoxidase converts H2O2 into hypochlorous acid (HOCl). 

Sonoma’s patented Microcyn® Technology optimizes our HOCl for superior efficacy and safety, while guaranteeing potency for the life of the product. With virtually no side effects, our customers use our line of products as often as needed to cleanse the skin, relieve irritations, and restore your well-being. 

Is hypochlorous acid natural? 

Yes – hypochlorous acid is naturally produced by your white blood cells so that you can defend against infection and bacteria. If you are injured and have a cut or wound on the skin, or have surgery that leads to scarring, your body uses naturally produced hypochlorous acid to kill harmful germs, fungi and bacteria.

What is Microcyn® Technology

Microcyn® Technology is as safe as water and has successfully achieved over 80 regulatory approvals. It stabilizes the hypochlorous acid used in our products to ensure that it retains its antipruritic, antimicrobial and anti-inflammatory properties. The Microcyn® Technology not only optimizes HOCl for superior efficacy and safety, but it also guarantees potency for the life of the product. With virtually no side effects or contraindications, you can utilize Microcyn®-based products as often as needed to cleanse skin, relieve irritations and restore your well-being and peace of mind. 

What is Sonoma’s Triple Mode of Action? 

Using our patented Microcyn® Technology to produce stabilized all-natural hypochlorous acid, our Triple Mode of Action has a profound impact on fighting infection, reducing inflammation, and improving the appearance of scars.  

The Triple Mode of Action in all Sonoma Pharma’s products are:  

  1. Anti-microbial - Microcyn® Technology breaks down the biofilm along with having impressive anti-pruritic, anti-microbial, anti-viral and anti-inflammatory properties. 
  2. Anti-inflammatory - our products treat common conditions while reducing infections, itch, pain, scarring and harmful inflammatory responses. 
  3. Regenerative – our products are gentle and safe solution that increases blood/oxygen flow to the wound, resulting in faster, more effective healing. 

How long will It take to see results? 

Results may vary for each person and each product, so it’s not possible to say exactly how long you will see results from using our products. Our products can be used daily or as often as needed and our customers generally see improvement with daily use in 4-5 weeks.
