Avoid Chemical-Based Sunscreens When Possible

Especially avoid chemical sunscreens in children younger than 6 months. For adults, prefer mineral sunscreens or physical barriers if concerned about endocrine-disrupting chemicals such as oxybenzone or avobenzone. If only chemical sunscreen is available on a high-UV day, use it only if necessary and sparingly, perhaps on sensitive areas like the face, ears, or neck rather than every day.
