Basic hypochlorous acid
My family has used hypochlorous acid for a long long time for everything from cuts and scrapes to pink eye to sunburns to preventing mold and mildew in kid cups and showers. It’s an amazing solution to so many things and even makes an awesome hand sanitizer. Plus it’s safe for consumption so can be used on kid toys or directly on skin. Despite packaging differences they’re pretty much all the same if they’re pure hypochlorous acid. Like others this one is not greasy, has no fragrance and is lightweight. It is water based so it’s moisturizing and prevents infection. At a current price of $14 for 2 ounces this is on the higher end. I think the value is just okay and worth comparing other brands (check ingredients!) but this small size is very handy for throwing in a beach bag or purse.

A versatile hypochlorus acid product from a well-known company
This product is billed as an after-sun spray, but really, it is so much more. It is actually a hypoclorous acid product, and a quick Internet search will tell you all of its possible uses. To summarize, hypoclorous acid is a disinfecting and soothing agent that—unlike rubbing alcohol or hydrogen peroxide—is very gentle on the skin. This product came with both a foil seal and in tamper-proof packaging, which I appreciated. The bottle included a separate optional spray pump, so that you can dab it on with a cotton ball or q-tip straight from the bottle, or use the spray for an all-over application. The ingredients showed that the product is made from only three ingredients: water, salt, and hypochlorus acid. It smells a bit like swimming pool water, but every fragrance-free hypochlorus acid product is going to smell like this because hypochlorus acid itself has a very faint chlorine scent. There are many hypochlorus acid products on the market. This one worked fine, and came from a known name brand, unlike most of the other options out there that are manufactured by no-name brands. If you are looking for a brand name option, this is a good one. If you don’t care about that, there are likely better values out there.

Finally, a after-sun mist that actually does something
I was skeptical - three ingredients, simple packaging, no dramatic claims — After a long day in the sun my face was red and hot, and I did a split test: sprayed it on one half and left the other alone. The difference was visible within minutes. The treated side calmed down, the redness faded faster, and it just felt immediately soothed. I went back and sprayed the other half immediately. The active ingredient is hypochlorous acid, which is actually something your own immune system produces — it's antimicrobial and anti-inflammatory without being harsh or sensitizing. No alcohol, no fragrance, no parabens, no dye. Nothing on this ingredient list that has any business irritating already-angry skin. It's pH balanced and truly non-stinging, which matters a lot when your skin is compromised. I've also been using it on insect bites and it's become my first reach for anything red and irritated. It takes down the swelling and calms the area noticeably. Not a substitute for antihistamine if you're having a real reaction, but as an immediate soothing step it's excellent.
