Blepharitis. If you know, you know. The constant eye irritation, the crusty lashes in the morning, the burning, the never-ending cycle of redness and discomfort. It’s one of those things that doesn’t sound like a big deal until you actually have it. Then? It’s all you can think about.
You’ve probably tried a bunch of things—warm compresses, baby shampoo, maybe even prescription ointments. Some of them work for a while, others not so much. But have you heard of hypochlorous acid? It might just be the solution your eyes have been waiting for.

What Even Is Hypochlorous Acid?
Let’s keep it simple. Hypochlorous acid (HOCl) is a naturally occurring molecule that your immune system actually makes to fight bacteria. Pretty cool, right? When used in a gentle spray, it helps cleanse your eyelids, reduce inflammation, and keep bacteria in check—all without stinging or irritating your already-sensitive eyes.
How to Use It for Blepharitis
Okay, so you’re intrigued. Now, let’s get into the how-to.

Start with clean hands. (Seriously. Don’t skip this.)
Close your eyes and spritz hypochlorous acid directly onto your eyelids. You can also spray it onto a clean cotton pad and gently wipe along your lash line if you prefer.
Let it air dry. No need to rinse—just let it do its thing.
Repeat twice a day. Morning and night are ideal, especially if your symptoms tend to flare up after sleeping.
That’s it. No complicated routines, no harsh chemicals, no weird side effects. Just a simple, effective way to keep your eyes feeling less awful.
Why It Works
Blepharitis is often caused by bacteria, clogged oil glands, or even Demodex mites (yes, tiny mites that live in your eyelashes—don’t Google it, trust me).
Hypochlorous acid helps by:
✔ Killing bacteria without disrupting your skin’s natural balance
✔ Breaking down debris along your lash line
✔ Reducing inflammation and irritation
✔ Creating a cleaner environment so your eyes can heal
Does It Actually Help?
For a lot of people, yes. Some notice an improvement in just a few days, while for others, it takes a couple of weeks. The key is consistency—don’t just use it when your eyes feel bad. Keep it in your routine to prevent flare-ups before they even start.
Any Downsides?
Not really. It’s super gentle, doesn’t burn, and won’t dry out your skin. Just make sure you’re using a high-quality, pure hypochlorous acid spray with no added junk.
