What is hypochlorous acid spray?

Hypochlorous acid (often shortened to HOCl) is a naturally-occurring molecule found in our immune systems, according to experts. It’s been a staple in the medical settings for a long time, but it’s HOCl’s antimicrobial and anti-inflammatory properties that have made it such a skincare savior.

Essentially, it may sanitize your skin of pore-clogging bacteria and may soothe skin inflammation and irritation, in addition to potentially having wound-healing properties. It’s because of this that social media users love to incorporate it into their in-flight or post-gym skincare routines.

Although having acid in the name might lead you to believe it’s a harsh ingredient, it’s actually quite gentle and safe to use on sensitive skin since it has a low pH.

For these reasons, it’s viewed as a multi-purpose solution to a number of skincare concerns.
