Sunscreen is a cornerstone of skin protection, but dermatologists say it shouldn't be your only line of defense. At recent dermatology symposia, experts highlighted a range of nonsunscreen UV protection strategies that can meaningfully reduce skin cancer risk and sun damage — especially for people who struggle with sunscreen reapplication or texture issues.

A viral TikTok from an Austin dermatology practice — racking up nearly 10 million views — kicked off the conversation by revealing that a standard white T-shirt has a UV protection factor (UPF) of just 5, meaning 20% of UV rays still reach the skin. That number drops further when the shirt is wet or worn out.

Key Takeaways:

• UPF-rated clothing is considered the most reliable nonsunscreen option — a UPF 50 garment blocks 98% of UV rays and has improved in breathability and comfort in recent years
• Hats help, but need a brim of at least 3 inches (ideally ~6.7 inches) to be meaningfully protective — and no hat fully shields the ears, neck, or chin
• UV window films for car side windows block up to 99% of UV rays, filling a gap that standard auto glass misses
• Supplements like Polypodium leucotomos extract (240 mg twice daily) have randomized trial support for reducing UV damage; omega-3s and carotenoids like lycopene also show promise

Why it matters: With skin cancer remaining one of the most common cancers globally, expanding the UV protection toolkit beyond SPF gives clinicians and patients more practical, adherence-friendly options — especially for those who work or spend significant time outdoors.
