For babies 6-12 months (infants), magnesium hydroxide in skin products is usually safe when it’s used in small amounts in baby-formulated products. Serious risks are rare, but there is some evidence that it can cause mild irritation to the skin, eyes, or breathing at higher strengths.
Use only products made for babies that list magnesium hydroxide. Don’t put it near your baby’s eyes, nose, or mouth. Don’t apply it to broken or red skin. Use the smallest amount needed and follow the product directions. If you see any redness, swelling, stinging, or breathing changes, stop use and rinse the area; contact your pediatrician if it’s more than mild.
Watch for redness, swelling, stinging, or eye irritation — limited evidence of these effects has been reported by regulatory reviews (European Chemicals Agency and Cosmetic Ingredient Review). Nano-sized forms may be more likely to be absorbed through skin (noted by NanoWerk). Some product certification programs require extra safety documentation or restrict use without it; choose baby-specific products and consult a pediatrician for frequent or large-area use.
