To the Editor Endocrine-disrupting chemicals (EDCs) disturb hormones and their actions. Of the hundreds of known EDCs, a subset are present in personal care products, making them relevant to dermatologists. As experts in the fields of endocrinology and epidemiology who conduct research on EDCs, we write to add a different perspective. The authors of a recent Editorial1 dismiss as nonscientific the clean beauty movement’s concerns about certain chemicals because its proponents are nonexperts. We take no stand on that movement. Instead, we point to a vast body of scientific studies2 showing that some of these chemicals, including phthalates3 and sunscreen ingredients (eg, oxybenzone),4 are EDCs. Formaldehyde is a Group 1 carcinogen according to the International Agency for Research on Cancer, and parabens are banned from cosmetics in the European Union.
