Sunscreen Guide: How to Pick, Apply, and Stay Protected Outdoors

Whether you’re at a motor‑race grandstand, a beach day, or just running errands, the sun can hurt your skin fast. A good sunscreen is the cheapest ticket to lasting skin health, and it’s easier than you think to use it right.

Choosing the Right Sunscreen

First, look at the SPF number. SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks roughly 98%. For most outdoor events, SPF 30‑50 is enough, but if you have fair skin or plan to be out for many hours, go higher.

Second, decide between chemical and mineral formulas. Chemical sunscreens soak up UV rays and feel light, but some people get irritation. Mineral sunscreens (zinc oxide or titanium dioxide) sit on top of the skin and are great for sensitive folks, though they can leave a faint white cast.

Third, check if it’s broad‑spectrum. That label means the product protects against both UVB (burn) and UVA (aging). Without broad‑spectrum, you’re only getting half the protection you need.

How to Apply Sunscreen Effectively

Most people under‑apply. The rule of thumb is about a teaspoon‑size amount for your face and neck, and a shot‑glass (about one ounce) for your whole body. It sounds like a lot, but it’s the amount that actually reaches the SPF rating on the label.

Apply sunscreen 15‑30 minutes before you step outside. This gives the ingredients time to bind to your skin. Don’t forget easy‑to‑miss spots: ears, the back of your neck, the tops of your shoes, and behind the knees.

If you’re sweating or swimming, reapply every two hours—or sooner if you get wet. Some sport‑specific sunscreens claim to be water‑resistant for up to 80 minutes; they’re handy for a day at the track where you might get drenched by spray.

Finally, pair sunscreen with other sun‑smart habits. Wear a wide‑brimmed hat, UV‑blocking sunglasses, and lightweight long‑sleeve shirts when the sun is strongest (10 am‑4 pm). These layers cut the amount of sunscreen you need and keep you cooler.

In short, pick a broad‑spectrum SPF 30‑50 product you like, use enough, and reapply regularly. Your skin will thank you years from now, and you’ll stay comfortable while cheering on your favorite drivers or enjoying any outdoor adventure.
