For children 5 years and older (school-age kids and teens) hypochlorous acid used on the skin is usually safe when used as directed. Most children will not have problems, but some people can get mild skin or eye irritation or breathing sensitivity if they inhale sprays or are exposed to contaminated or poorly made products.
Use only products made for skin use and follow the label. Avoid spraying directly at your child’s face—spray on hands or a cloth instead. Do a small patch test on the arm and wait 24 hours before wider use. Do not mix with bleach or other household cleaners. Buy sealed, stabilized products from reputable brands and check expiration dates. If you see redness, stinging, swelling, or any breathing trouble, stop use and call your child's doctor.
Watch for signs of contamination or harmful byproducts (listed by environmental and health agencies) such as chlorine-like smell or unexpected strong irritation—discard the product if it smells very chemical. Animal and lab studies suggest possible breathing or allergic effects at low doses and cellular oxidative stress in some tests (references from Environment Canada and the U.S. National Library of Medicine and a published cellular study). Also note that some regulatory sources allow limited uses in food, which is not the same as unrestricted skin use (U.S. FDA). If your child has asthma or very sensitive skin, be extra cautious with sprays and talk to your pediatrician first.
