When you step outside, your skin is exposed to ultraviolet radiation, invisible rays from the sun that can damage skin cells and lead to premature aging or skin cancer. Also known as UV rays, this radiation comes in two main types—UVA and UVB—that penetrate differently and require different defenses. Most people think UV protection means slathering on sunscreen at the beach, but it’s needed every day, even when it’s cloudy or you’re just walking to your car.
Sunscreen, a topical product designed to absorb or reflect UV radiation, is the most common tool for UV protection, the practice of shielding skin from harmful sun exposure. But not all sunscreens are equal. Broad-spectrum formulas that block both UVA and UVB are essential. SPF 30 is the minimum recommended, and you need to reapply every two hours—or after sweating or swimming. Still, sunscreen alone isn’t enough. Hats, sunglasses, and seeking shade are just as important. People who spend time outdoors regularly, like gardeners, construction workers, or athletes, often miss this: UV damage adds up over years, even if you don’t burn.
UV exposure doesn’t just hurt your skin. It can weaken your immune system, cause eye damage like cataracts, and even interact with certain medications. For example, some antibiotics, acne treatments, and blood pressure drugs make your skin more sensitive to the sun. If you’re on any regular medication, check if it increases your risk of sunburn. And while some supplements like fish oil or antioxidants are often talked about for skin health, they don’t replace proper UV protection—they might help a little, but they’re not a shield.
