Don’t get burned by bad advice: UF dermatologist shares sun safety tips

With Florida’s year-round sunshine and record-breaking heat, protecting your skin isn’t just about avoiding sunburns; it’s about reducing the long-term risks of aging and skin cancer. 

To help cut through the myths and confusion, Abel Torres, M.D., chair of the University of Florida Department of Dermatology, explains why sunscreen is a daily essential, clears up common misconceptions and shares practical tips for keeping your skin safe in Florida’s intense ultraviolet environment.

Why is sunscreen so important?
Sunscreen prevents sun damage, which causes skin aging, and it helps protect against skin cancer. Sun exposure is one of the leading causes of skin cancer.

What is the biggest misconception about sunscreen?
That once you put it on, you’re fully covered. In reality, sweating, swimming and time reduce its effect, so it must be reapplied.

Are mineral or “reef-safe” sunscreens better?
Both chemical and mineral sunscreens are safe, according to the FDA. Current evidence doesn’t show harm at real-world levels.

Do high SPF sunscreens really make a difference?
Higher SPF means more UVB protection, but UVA, visible light and infrared rays also damage skin. People with darker skin benefit from tinted sunscreens with iron oxide for added protection.

How often should sunscreen be reapplied?
Every two hours with a water-resistant sunscreen, and more often if your sunscreen isn’t water resistant or if you’re very active.

Do people need sunscreen every day?
Ideally yes, especially during peak hours. If you’re indoors most of the day, you may not need it as much.

Are people with darker skin less at risk?
They’re more tolerant but not immune. Anyone can burn and should use protection.

What areas are often forgotten?
Hands, feet, ears and legs. Even the soles of your feet can develop melanoma.

What is one myth you’d like to clear up?
That cloudy days are safe. Harmful rays still pass through clouds and can damage skin.

What else can people do to prevent skin cancer?

Avoid peak sun when possible, wear protective clothing and hats, and check your skin regularly. If you see something new or changing, get it looked at.
