The name sounds like something you'd keep under the sink, and that's probably why so many people search it before buying. Hypochlorous acid, HOCl for short, is something your body already makes. White blood cells produce it to deal with bacteria. Skincare companies make a very weak version by running electricity through salt water, then stabilize it so it keeps in a bottle.
Dermatologists have used it for years, mostly for cleaning wounds and prepping skin before procedures. It only turned into a face mist people buy for themselves in the last few years.
We sell one, so take this with that in mind. Everything below comes from what dermatologists have said in interviews with Banner Health, Paula's Choice, Marie Claire and CBS, not from us.
How strong is it?
Barely. One dermatologist puts skincare products at about 0.005% to 0.02%. That's the whole point: it's gentle enough to spray on your face and leave there.
Which is also why you should never make your own. Hypochlorous cleaning sprays exist, and watering one down at home won't get you to a face-safe strength. Buy something sold for skin.

How people use it
Wash your face, close your eyes, spray a few times from a few inches away, and let it dry. No rinsing. Then moisturizer, or whatever comes next in your routine. Once or twice a day is typical, but the label on your bottle wins.
People reach for it after shaving or waxing, after the gym, on a plane, or when their skin can't handle stronger stuff. A couple of the doctors interviewed said patients tell them their breakouts calm down while using it. They were also clear that it isn't an acne treatment and doesn't replace anything you've been prescribed.
When to skip it or ask first
Try it on a small patch of skin before your whole face, especially if you react to things easily. If it stings or turns red, stop. Keep it off open cuts unless a doctor told you otherwise. And if you're pregnant or already being treated for a skin condition, it's worth a quick question to your dermatologist.
Is it bleach?
No. Both involve chlorine, but bleach is sodium hypochlorite at a far higher strength. Different compound, different job.
Ours
Our hypochlorous facial spray is a 30ml bottle for $5.96. Small enough for a carry-on, cheap enough to find out whether you like it. If you want something to go with it, the silicone cleansing brush is what we'd add.
