For children aged 5 years and older (school-age kids), benzoic acid used on the skin in regular cosmetic products is usually low risk when used at normal concentrations. It is a preservative and is not known to cause cancer or long-term developmental harm in people, but some countries and safety panels limit how it is used.
Use products labeled for children or products that list ingredient concentrations when possible. Do a small patch test on the inside of the forearm and wait 24 hours before wider use. Don’t put products with benzoic acid on broken, irritated, or very sensitive skin. If your child has a history of skin allergies, choose a product formulated for sensitive skin and talk with your pediatrician.
Watch for redness, itching, rash, or other signs of skin irritation — stop use if these happen. Some safety reviews and national authorities have limits on how much benzoic acid can be used in cosmetics, and some product certification programs may restrict its use without extra safety data. If you see a product that does not list its intended use or concentration, consider choosing a different product or asking the manufacturer for more information.
