Skin Cancer Awareness Month: Debunking the Year's Worst SPF Myths
Clearing up misinformation when it matters most.
FDA absorption studies found chemical filters can exceed 0.5 ng/mL in blood — which triggers further study, not a safety verdict.
The 2021 benzene findings involved a manufacturing contaminant, not a sunscreen ingredient.
Frequently asked questions
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.
Is DIY sunscreen safe?
No. Homemade sunscreens can't be reliably tested for SPF or even coverage, and ingredients like coconut oil or zinc stirred into a cream don't disperse evenly enough to protect skin. Dermatologists strongly advise against DIY sunscreen; use a regulated, lab-tested product.
Should I worry about benzene in sunscreen?
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.
