For 6–12 month old babies (infants): this ingredient can cause skin allergy or irritation and may contain or release small amounts of formaldehyde. Babies’ skin is still delicate, so there is a moderate risk.
When possible, pick products that do not list DMDM Hydantoin. If you must use a product that contains it, prefer rinse-off products (bath washes) rather than creams left on the skin. Don’t use it on broken, red, or eczema-prone skin, and avoid the diaper area. Do a small patch test on the baby’s arm and wait 24–48 hours before wider use. If any redness, rash, swelling, or breathing difficulty appears, stop use and contact your pediatrician.
There is strong evidence that this ingredient can irritate skin and cause allergic reactions (based on cosmetic safety reviews and peer-reviewed reports). There is also a contamination concern because it can release or contain formaldehyde; some countries place limits or restrictions on its use. Avoid products with DMDM Hydantoin for babies with eczema or known sensitivities, and watch for rashes or breathing problems. Sources of these warnings include official safety reviews, regulatory limits from health authorities, and peer-reviewed studies.
