For toddlers (1–2 year olds) topical phytonadione (vitamin K1) is probably low risk for long-term harms, but some regulators ban its use in cosmetics. That means it’s not a routine ingredient you should use on your child unless a doctor says it’s okay.
Check product labels and do not use products that list phytonadione for everyday cosmetic use on your toddler. If a healthcare provider recommends a product with this ingredient, try a small patch test on a tiny area and watch for 48 hours. If the skin looks red, swollen, or your child has trouble breathing, stop use and seek medical care. Always follow your pediatrician’s advice first.
Regulatory warning: this ingredient has been restricted or banned for cosmetic use in some places (EU Cosmetics Directive). Also, there is limited evidence it can cause skin or lung irritation (European Chemicals Agency). These are the main reasons to avoid routine cosmetic use on young children. Environment Canada notes it isn’t expected to be broadly toxic, but the regulatory restriction is the strongest signal to be cautious.
