Sun Protection: What Actually Works and What Doesn't
When it comes to sun protection, the practices and products used to shield skin from harmful ultraviolet radiation. Also known as UV protection, it’s not just about avoiding a bad burn—it’s about reducing your risk of skin cancer and premature aging. Most people think sunscreen is the whole story, but that’s not true. Sun protection includes clothing, shade, timing, and even the type of sunscreen you choose. Skipping any one piece leaves you exposed.
UV radiation is the real enemy here. It comes in two main types: UVA, which digs deep into your skin and causes wrinkles, and UVB, which burns the surface and triggers DNA damage that can lead to skin cancer, a group of diseases caused by uncontrolled growth of abnormal skin cells due to UV exposure. The damage adds up over time, even on cloudy days or through windows. That’s why daily protection matters, not just beach days. And no, a tan isn’t safe—it’s your skin screaming for help.
Not all sunscreens are created equal. Look for broad-spectrum, SPF 30 or higher, and water-resistant labels. But even the best sunscreen wears off. Sweating, rubbing, and time all chip away at its protection. That’s why combining it with a wide-brimmed hat, UV-blocking sunglasses, and seeking shade between 10 a.m. and 4 p.m. gives you real coverage. Clothing with UPF ratings works better than most people realize—a dark, tightly woven shirt can block more UV than some lotions.
Some myths still cling on. Higher SPF doesn’t mean you can stay out all day. SPF 100 isn’t twice as good as SPF 50—it’s barely better. And spray sunscreens? They’re easy to miss spots with. Rubbing it in helps. Also, don’t forget your ears, lips, neck, and feet. Those are common spots for skin cancer because they’re overlooked.
People with darker skin think they’re immune. They’re not. While melanin offers some protection, skin cancer in darker skin tones is often diagnosed later—and that’s deadly. Everyone needs sun protection. Kids? Even more so. Childhood sunburns double your lifetime risk of melanoma.
What you’ll find below isn’t a list of products. It’s a collection of real, evidence-based insights on how sun protection actually works—what saves lives, what’s just marketing, and how to build habits that last. No fluff. No hype. Just what you need to know to keep your skin healthy, year after year.
