For adults: octinoxate can be absorbed through the skin and some studies suggest it can act on the body’s hormones. Occasional, limited use is unlikely to cause harm for most adults, but there are reasons to be cautious with frequent or full-body use and during pregnancy.
If you are an adult using products with octinoxate: 1) Use sparingly and avoid applying it over large areas of broken skin; 2) Prefer using it on exposed areas only rather than whole-body daily use; 3) Consider non-chemical (mineral) sunscreens with zinc oxide or titanium dioxide if you want to avoid this ingredient; 4) If pregnant or trying to conceive, talk with your healthcare provider about sunscreen choices; 5) If you notice an unusual rash after sun exposure, stop use and see a healthcare provider.
Watch for sun-related allergic rashes (photoallergic reactions) reported in human case studies, and be aware that human absorption studies and several animal studies raised concerns about effects on hormones and development — regulatory reviews in some regions have noted endocrine-related effects. These are the main reasons for caution.
