Magnesium hydroxide is generally safe for toddlers (1–2 years) when used on the skin. It has low long-term health concerns, but a small number of studies show it can irritate eyes or skin in some cases.
Use products made for children and follow the product directions. Do a small patch test on the inside of the forearm first. Avoid putting the product near the eyes, nose, or mouth, and do not use on broken or very irritated skin. If the product is a powder, avoid breathing it in and do not use raw powders or any product that says it is nanoscale. If you see redness, swelling, rash, eye irritation, or any breathing problems, stop use and talk to your pediatrician.
Watch for skin or eye irritation (source: European Chemicals Agency and Cosmetic Ingredient Review). Avoid powders or products that advertise nanoscale particles because they may behave differently on the skin (source: NanoWerk). Some safety reviews note the ingredient should be formulated to avoid irritation, so prefer products explicitly made for babies and toddlers and follow manufacturer guidance (source: Cosmetic Ingredient Review).
