Halloween face paints can be harmful to children's skin

What the research found

US and UK health guidance says face paints can cause rashes, skin irritation and allergic reactions. Products made for children can still cause problems. Some products have been recalled for harmful ingredients, including heavy metals such as lead and mercury.

Guidance also points to latex, nickel and cobalt as ingredients that can cause sensitivities. Old or shared face paint can carry bacteria. This can lead to infection if it touches broken skin. A strong bad smell can be a sign of contamination.

A 24-year Turkish study (2021) found allergy to a common preservative in leave-on and rinse-off cosmetics, such as wet wipes, causing hand and face eczema. It didn't test face paints or children specifically. It shows cosmetic ingredients can trigger skin allergy.

What it doesn’t mean

• This doesn't mean every face paint is unsafe. The guidance describes risks and ways to lower them. It doesn't say how common reactions are in children.
• Test a small dab on your child's arm a few days before Halloween. Check the label, keep paint away from the eyes, and don't reuse old or shared products. Throw out anything that smells bad.
• If your child has a rash, swollen eyelids or signs of infection after using face paint, see a GP. Take extra care if your child has allergies or eczema.
