For children aged 2-5 years (toddlers, preschoolers), magnesium hydroxide used on the skin is generally low risk when it’s part of a normal product made for skin. Most health reviews find little or no risk for cancer or long-term effects. Small risk: it can sometimes irritate eyes, nose, or skin if the product is strong or if the ingredient is in tiny “nano” form.
Choose products made for children or gentle skin formulations. Do a small patch test on a little area of skin first. Use sparingly and avoid putting it on broken, red, or raw skin. Keep products away from the child’s mouth and eyes and supervise use. If your child has sensitive skin or you plan regular use (for example daily), check with your pediatrician.
Watch for signs of irritation (redness, stinging, rash, swelling) or breathing issues. Stop use and rinse the area if those appear. Safety reviews and regulatory panels note limited evidence of eye, skin or respiratory irritation (European chemical safety reports and industry safety reviews). Some sources raise caution about nanoscale forms that might change how the material is absorbed through skin (nano-specific notes). Also, some product verification programs require extra safety data before the ingredient is allowed — choose products that are clearly intended for children and avoid DIY mixtures with “nanopowder” or very concentrated forms.
