"This helps to soothe the skin whether it's from a sunburn, skin irritation, cuts or scrapes," dermatologist Marisa Garshick explained. "It can be used as needed and helps to reduce bacteria, redness and calm the skin."

This hypochlorous acid version is my personal favorite thanks to its stability and FDA-cleared formula. (Hypochlorous acid is a notoriously difficult ingredient to stabilize, but this version has a two-year shelf life, per the brand, which is purportedly twice as long as usual.) I keep a bottle on my vanity at all times and make sure to never run out!

Promising review: "I have used this spray for several instances since I purchased it a few months ago. It has an almost instant soothing effect on the skin/affected area. I had a bacterial infection in my chest area, and it soothed and cleared it up within a week! However, I became totally sold on this product whenever my toddler son came home with Hand, Foot, and Mouth disease. I sprayed this on his affected areas 2-3 times a day, and his skin was not irritated like normal with this illness. If you know anything about HF&M, it can be uncontrollable and extremely uncomfortable for a child, and this spray kept his bumps at bay! All of the bumps he did have healed within a few days. I have vowed to always keep a bottle of this magic spray on hand; it's totally worth the price!" -- Magic Spray
