How to Incorporate HOCl into Your Routine

To make the most of Hypochlorous Acid, here are some tips gleaned from Reddit users:

  • Application After Cleansing: Many users apply HOCl spray to clean, dry skin after cleansing and before other serums or moisturizers.
  • Let it Dry: It’s generally recommended to let the HOCl spray dry completely on your skin before applying other products. Some suggest waiting, especially before applying other active ingredients.
  • Use Throughout the Day: Some users keep a bottle handy to spritz their face after workouts, during long shifts, or whenever their skin feels irritated.
  • Consider it an Active: Some treat HOCl like an active ingredient in their routine and avoid using it in the same application as other strong actives like retinoids or chemical exfoliants.
  • Patch Test: As with any new skincare product, it’s always wise to patch test on a small area of your skin first to check for any adverse reactions.
  • Storage: While not explicitly detailed in all sources, general skincare knowledge suggests storing HOCl in a cool, dark place and ensuring the bottle is tightly closed to maintain stability.

The Not-So-Good: Potential Drawbacks and Considerations

While the buzz is largely positive, some Reddit users have reported:

  • Dryness: A few individuals found HOCl to be drying, similar to how pool water can affect the skin. This might be more likely with frequent use.
  • Lack of Effectiveness for Everyone: As with any skincare ingredient, HOCl isn’t a universal solution, and some users didn’t experience significant benefits.
  • Concerns about Skin Microbiome: Some have raised questions about whether HOCl could negatively impact the skin’s beneficial bacteria. While some argue it’s gentle enough not to harm the good bacteria, this is still a topic of discussion.
  • Stability: There are mentions of HOCl potentially degrading when exposed to light and air, highlighting the importance of proper packaging and storage.
