Can a Hypochlorous Acid Spray Really Treat Eczema?

Myth Busted

Your ‘gentle’ spray might be a disinfectant—here’s what it actually does to broken skin.

Expert Analysis · Honest Reviews · Real Results

1.🔬Disinfectant on a rash?

You’re spraying a wound disinfectant on your face and calling it skincare. Yeah, I said it.

Tower 28 Beauty sells this as a “Daily Rescue Spray,” but the active ingredient is hypochlorous acid — the same stuff in hospital-grade wound washes. It kills bacteria on contact. That’s the point. But when your skin barrier is already screaming from eczema, “killing” isn’t the same as “healing.”

2.🧪What You’re Actually Buying

It’s $30 for 4 oz. The claim: calms redness, clears breakouts, reduces eczema flare-ups. I bought it because the TikTok algorithm cornered me at 2 AM.

Hypochlorous Acid 0.015%

The exact concentration that kills bacteria without nuking your skin — in theory

Sodium Chloride

Fancy word for salt. It’s there to stabilize the formula, not hydrate

No Fragrance, No Alcohol

Good — but also means zero soothing agents. It’s sterile water with attitude

3.🩹What’s Actually In It

Here’s the thing nobody mentions: hypochlorous acid is a bleach derivative. It’s gentle on intact skin, but eczema is *broken* skin. The ingredient list is brutally short — that’s the point. It’s a disinfectant, not a moisturizer.

Hypochlorous Acid: Kills bacteria on contact — the ‘disinfectant’ part
Sodium Chloride: Stabilizer, does nothing for your skin barrier
Water: The base. That’s it. Nothing to repair anything
No Ceramides: The thing your eczema actually needs to heal

4.💧The Feel Test

It sprays like a fine mist. Evaporates in seconds. No residue, no stickiness — you’ll forget you even used it. First week, my flare-ups looked less angry. Redness calmed down about 30%, which surprised me.

Week three, my skin got tight. Not hydrated-tight — “I need moisturizer immediately” tight. The spray kills bacteria, but it also strips the little natural oils your broken barrier has left.

💡

One Thing: Spray it on a cotton pad and dab — don’t mist directly. You’ll avoid the over-saturation that leaves your skin drier than before.

5.⚠️The Brutal Verdict

My eczema patches didn’t spread or get infected — that’s the win. But they didn’t actually heal either. The inflammation calmed, the dryness got worse. It’s a disinfectant, not a repair cream.

✅

Buy if

You get acne *and* eczema and need something that kills bacteria without clogging pores

⏭️

Skip if

Your eczema is dry, flaky, or cracked — you need ceramides, not bleach water

💰

Worth it?

$30 for a bacteria-killing mist is fair — just don’t expect it to fix your skin barrier

6.✅Final Call

It’s a great antiseptic. It’s a terrible eczema treatment. Use it on active breakouts, not broken skin.

5.5/10

Kills bacteria, won’t heal eczema
