Why Gen Z's Sun Habits Worry Dermatologists

Benzene isn't a sunscreen ingredient — it's a contaminant detected in a limited number of products due to manufacturing issues, which prompted recalls. Its presence doesn't mean sunscreen is unsafe to use, and experts stress the proven risk of skipping sun protection is far greater. Buy from reputable brands.

Often it isn't. Studies and dermatologists have flagged widespread sunscreen misinformation on social media — from 'sunscreen causes cancer' to anti-SPF and DIY trends. Rely on dermatologists and primary sources (AAD, FDA, peer-reviewed research) rather than viral claims.

The evidence is mixed but reassuring: most studies find that sunscreen, as people actually use it, does not cause vitamin D deficiency — partly because no one blocks 100% of UV. If you're concerned, dietary sources and supplements are a safer route than deliberate unprotected sun exposure.
