Before heading out for the day, do you apply sunscreen?

Even when it’s cloudy, sunscreen should be a daily habit. Sunscreen is the easiest way to help prevent skin cancer, which affects one in five Americans.

Follow these simple tips to protect yourself from skin cancer.

Cover Up

Long sleeves, a hat and UV-blocking sunglasses can ward off the worst of the sun’s rays.

Wear Sunscreen

Choose a sunscreen that is rated at least SPF 30, which can block 97% of the sun’s rays. However, since no sunscreen can block all the sun’s rays, SPFs beyond 30 provide minimal additional protection. Make sure your sunscreen says “broad spectrum,” which means it blocks both UVA and UVB rays.

Wear Sunscreen, For Real

Sunscreen is only effective if you really wear it — most people don’t apply nearly enough. To get the full benefit, you need about 1 oz (about 2 tablespoons) to cover your entire body. To stay protected, reapply every two hours, more often if you’re sweating or swimming.

Check Yourself

Many skin cancers are treatable if they’re caught early, so examine your skin every month for new or changing freckles or moles. If you notice something unusual, get it checked by your physician or a dermatologist. Call (800) USC-CARE to make an appointment with a physician near you.
