For school-age children (5 years and older): this ingredient is a chemical sunscreen ingredient that can be absorbed through the skin and has been linked in studies and regulatory reviews to possible hormone-related and developmental effects. Because older children are less sensitive than babies and toddlers, the risk is lower than for younger ages, but it is still not a first choice.
If your child is 5 or older, prefer sunscreens with mineral filters such as zinc oxide or titanium dioxide when possible. If a product lists 4βMethylbenzylidene Camphor and you must use it, use it sparingly on small areas, avoid applying to broken or irritated skin, do not use it daily, and wash it off after sun exposure. For everyday protection, rely on clothing, hats, and shade whenever possible.
Watch for skin redness or rashes after use and stop use if that happens. The concern comes from scientific studies and regulatory reviews (for example, the European Chemicals Agency and scientific committee reviews) that note limited but real evidence of hormone-related and developmental effects, and from regulatory opinions that restrict its use. Also note studies showing this ingredient is absorbed through the skin and can accumulate. Because of these concerns, avoid using this ingredient on younger children (infants, newborns, toddlers) and choose safer alternatives for regular use.
