Everyday exposure	5/10	In a randomised trial of 48 adults applying sunscreen to 75% of the body, homosalate reached geometric mean peak plasma concentrations of 13.9-23.1 ng/mL across three spray formulations, above the FDA's 0.5 ng/mL threshold after a single application.

What this means for you

After an EU scientific committee flagged possible endocrine activity, the permitted level was cut from 10% to 7.34% and restricted to face products. It is still allowed at 10% elsewhere, including the US. Do not stop using sunscreen over this — change the filter instead.
