For newborns and babies 0–6 months, Dmdm Hydantoin is best avoided. It can release formaldehyde and is known to cause skin irritation and allergic reactions, and babies have very sensitive, thin skin.
Choose products labeled preservative-free or free of formaldehyde-releasing preservatives for infants. Avoid using products that list Dmdm Hydantoin on the ingredient label on baby skin, especially on the face, folds, or damaged skin. If you must use a product that contains it, prefer short contact (rinse-off) products and test on a small area first; stop use at the first sign of redness, rash, swelling, or itching.
Watch for redness, bumps, swelling, itching, or any new rash after using a product with this ingredient — these are signs of an allergic reaction or irritation (based on safety reviews cited for this ingredient, including Cosmetic Ingredient Review and other regulatory sources). There is also a contamination concern for formaldehyde noted in the ingredient data; do not use on broken or inflamed skin. Some countries restrict or limit its use in certain cosmetics (Japan cited), which is why extra caution is advised for infants.
