Skincare is full of trending ingredients, but hypochlorous acid is quietly gaining attention and looks set to be the next big thing.

You might have noticed it appearing in mists, serums, and cleansers recently, but if you’re still wondering why everyone’s buzzing about it, you’re not the only one. This low-key ingredient is suddenly everywhere, and beauty experts can’t stop raving.

So, here’s everything you need to know about hypochlorous acid.

What is Hypochlorous Acid?

Hypochlorous acid is a weak acid with strong antimicrobial properties, which means it can be used to reduce skin inflammation, treat acne breakouts, and even soothe eczema on the skin.

If you’ve taken to wiping every germ-filled surface with Clorox wipes ever since the pandemic hit, then you’re already partially acquainted with this anti-bacterial ingredient.

This not-so-secret ingredient in Clorox wipes (Clorox, hypochlorous?), hypochlorous acid isn’t only used to disinfect surfaces; it’s also used on open wounds (though not in Clorox wipe form, for sure) to promote healing, and by dermatologists on the skin before they perform skin-barrier-breaking procedures like laser treatments.

What Is So Great About Hypochlorous Acid?

Hypochlorous acid is a gentle, non-stripping antimicrobial ingredient that works well for all skin types. Unlike alcohol or benzoyl peroxide, it won’t dry out or irritate the skin. Naturally produced by our white blood cells, HOCl helps fight pathogens and disinfect, but skincare products provide an extra boost where it’s needed.

Since it’s already present in the skin, similar to hyaluronic acid, hypochlorous acid can be used immediately without a gradual introduction. You can apply it directly to acne spots, sunburned areas, or irritated skin to soothe inflammation and support healing.

Here’s a clear breakdown of its benefits:

  • Disinfects the skin
  • Reduces inflammation
  • Encourages faster healing
  • Helps with sunburn, acne breakouts, eczema, and psoriasis
  • Suitable for all skin types

Hypochlorous acid can be infused into a myriad of skincare products including cleansers, serums, and moisturisers but, right now, this soon-to-be-buzzy ingredient is most commonly available in sprays.

Adopted into a skincare routine, it should look like this: cleanser, hypochlorous acid spray, other skincare products, and then moisturiser. You can spray it over your face in a light layer to help with disinfection and reducing inflammation, and carry on with the rest of your routine as per normal.

For targeted use on acne spots, itchy eczema skin, or sunburnt areas, just reach for the hypochlorous acid spray and spritz, spritz, and spritz again!
