For children aged 5 and older (school-age kids), magnesium chloride is generally safe when used on the skin in normal amounts. Safety reports give it a low concern for cancer, allergies, and effects on growth or reproduction.
Use products with magnesium chloride on intact skin only. Do a small patch test on the inside of the forearm and wait 24 hours to check for any redness or itching before wider use. Keep products away from eyes and mouths. If you plan to use it over a large area, on broken skin, or your child has kidney disease or takes medicines that affect minerals, ask your child’s doctor first.
Avoid putting magnesium chloride on cuts, sores, or very irritated skin because it can cause mild irritation (source: the ingredient safety data and product reports). Watch for signs of an allergic reaction or irritation — redness, swelling, itching, or hives — and stop use if these occur. Because the ingredient data also notes its regulatory listings (U.S. FDA and Environment Canada), check with a healthcare provider for children with kidney problems or those taking medications that change mineral balance (source: U.S. FDA and Environment Canada entries in the ingredient data).
