Why the New Filter Won't End the 'US Sunscreen Sucks' Debate Overnight
One approval, lots of nuance.
AAD (2025): 32% of Gen Z scored a 'D' or 'F' on basic sun-protection knowledge.
FDA's Janet Woodcock: absorption of an ingredient does not by itself mean the ingredient is unsafe.
Questions we get a lot
Is sunscreen misinformation on TikTok true?
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.
Does daily sunscreen affect vitamin D?
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.
Is sunscreen actually bad for you?
For the vast majority of people, no — major dermatology bodies consider sunscreen safe and effective, and the proven risks of unprotected UV (skin cancer, premature aging) are far greater. The FDA is studying how some chemical filters are absorbed, but absorption alone does not mean harm.
