Hypochlorous Acid: Helpful or Harmful?

As an esthetician with over a decade in the industry, I’ve seen trends come and go.

I’ve gone all-in on some of them before—trusting reps, marketing, and the excitement around “the next big thing.” But over the years, I’ve learned to slow down, observe, and really do my research—especially when it comes to long-term effects on the skin and the skin’s microbiome.

One trend I’m seeing right now is the overuse of hypochlorous acid sprays.

Now, don’t get me wrong—hypochlorous acid has its place. It’s a naturally occurring compound in the body, known for its antimicrobial and wound-healing properties. In the right context, it can be amazing for acne-prone or sensitive skin.

But here’s the thing: more isn’t always better.

Using too much, too often, can throw off the skin’s natural balance. Your skin has a delicate microbiome—a protective ecosystem of bacteria that keeps things healthy, resilient, and functioning as it should. When you constantly spray with something antibacterial (yes, even a gentle one like HOCl), you risk disrupting that balance.

That can lead to:

• Increased sensitivity

• Dryness or irritation

• Even more breakouts in the long run (yep, defeating the original purpose)

The skin industry is super oversaturated—so many products, some fantastic, and others… not so much. It’s easy to get swept up in the hype, especially when something gets a ton of influencer or brand attention.

All I’m saying is: pause before you overdo it.

Trendy doesn’t always mean necessary—or safe for long-term use. Respect your skin, protect your microbiome, and don’t be afraid to ask questions or take your time before jumping all in.
