Summer sunshine is something many of us look forward to all year. But before you head outside, it s worth asking yourself an important question: is your sunscreen actually protecting your skin the way it should? Not all sunscreens are created equal, and using the wrong one, or applying it the wrong way, can leave your skin vulnerable to sunburn, early aging, and even skin cancer.
The Basics: What to Look for on the Label
To start, check that your sunscreen is labeled “broad-spectrum.” This means it protects against both UVA and UVB rays. UVA rays can cause premature aging, while UVB rays are responsible for sunburn. You ll want protection from both.
Next, make sure the sunscreen is SPF 30 or higher. While SPF 15 is better than nothing, dermatologists recommend SPF 30 as a minimum for daily use. If you’re spending time outdoors, sweating, or swimming, a water-resistant formula will offer more reliable coverage.
How You Use It Matters
Even the best sunscreen won t help much if it s applied too thinly or too late. Apply a generous layer to all exposed skin at least 15 minutes before going outside. Don t forget often-missed spots like your ears, the back of your neck, your hands, and your feet. Reapply every two hours, or more often if you re in the water or sweating. Using makeup or moisturizer with SPF? That s a nice bonus, but probably not enough on its own for long days outside. Layering a dedicated sunscreen underneath will give your skin better protection.
When to See a Dermatologist
If you re unsure which sunscreen is right for your skin type, or if you ve noticed changes in your skin—like new moles, spots that won t heal, or irritation after sun exposure—it s time to see a dermatologist. They can recommend the best sun protection for your lifestyle and screen for early signs of skin damage or cancer. Sunscreen is one of the simplest and most powerful tools we have to protect our skin.
