For adults: magnesium carbonate used on the skin in cosmetics and personal care products is generally safe. It’s used to absorb moisture and prevent clumping and has a very low level of health concern in available safety assessments.
If you’re an adult using a product that contains magnesium carbonate: do a small patch test on the inside of your forearm before full use, avoid putting the product on cuts or broken skin, don’t breathe in dusty powders, avoid getting it in your eyes, and stop use and rinse with water if you get redness, itching, or irritation. If you are pregnant or have specific health concerns, check with your healthcare provider.
Watch for any signs of skin irritation or allergic reaction — this is the main issue to look out for. Safety assessments and regulatory reviews (including Environment Canada assessments referenced for this ingredient) list low concern for cancer, allergy, reproductive or long-term organ harm, but they note that topical sensitivity can still occur in rare cases. Also avoid inhaling the ingredient if it’s in a loose powder form and avoid applying it to open wounds.
