Sun Protection: What Works, What Doesn’t, and How to Stay Safe

When you step outside, your skin is exposed to UV radiation, invisible rays from the sun that damage skin cells and increase cancer risk. Also known as ultraviolet light, it’s the main reason for sunburn, early wrinkles, and most cases of skin cancer. No matter your skin tone, skipping sun protection isn’t a risk you can afford to take.

Sunscreen, a topical product designed to block or absorb UV rays, is the most common tool for sun protection. But not all sunscreens are equal. Look for broad-spectrum labels that guard against both UVA (aging) and UVB (burning) rays, and choose SPF 30 or higher. Reapplying every two hours — or after swimming or sweating — isn’t optional. It’s the difference between protection and just a false sense of safety. And sunscreen alone isn’t enough. Hats, sunglasses, and shade from trees or umbrellas play a real role. Clothing with UPF ratings gives you extra defense without needing to reapply. Even on cloudy days, up to 80% of UV rays still reach your skin.

Skin cancer prevention, the goal of consistent sun protection, isn’t just about avoiding sunburns. It’s about stopping damage before it turns into something dangerous. Melanoma, the deadliest form, often starts from repeated UV exposure over years. Studies show people who use daily sun protection cut their risk of melanoma by up to 50%. That’s not a small number. It’s life-changing. And it’s not just for beach days. Walking the dog, commuting, or sitting by a window can add up.

You’ll find posts here that break down what ingredients actually work in sunscreen, why some products fail, and how to choose one that fits your skin type. Others explain how sun damage shows up years later — like dark spots or uneven texture — and what you can still do about it. There’s also guidance on protecting kids, managing sun sensitivity from medications, and spotting early signs of trouble. This isn’t about fear. It’s about knowing what matters, cutting through the noise, and making simple choices that add up to real protection.
