Sun protection is important year-round, but it’s often top of mind during the summer months.

“If the sun is shining bright enough that you don’t need a flashlight to see, then you need sunscreen,” said Salem Health physician Jeffery C. Brown, MD.

To help you stay on the bright side of skin care, Dr. Brown shared the common myths around sunscreen — and what you need to know before stepping out into the sun.

Myth #1: The higher the SPF number, the better the protection.

Brown said SPF 30 is enough, and it’s not worth spending more money for a higher number. Instead, focus on how often you are reapplying.

“This stuff wears off. It’s only good for about two hours,” he said. “If you go swimming, if you take a shower, you’re washing it off.”

Myth #2: I tan but don’t burn, so I don’t need sunscreen.

Any time you expose your skin to enough sun to create a tan – without protection, you’re placing yourself at risk for cancer.

“That applies to people who aren’t Caucasian, too,” said Brown. “That applies to African Americans, Hispanics. You can still expose your skin to enough rays that it can cause cancer.”

Myth #3: I won’t get enough vitamin D if I wear sunscreen.

Vitamin D is important for bone health, and physicians find most people get enough of it. Therefore, wearing sunscreen will not decrease your vitamin D intake.

If you’re concerned, talk to your primary care provider about a supplement, but don’t skip sunscreen.

“That’s the equivalent of saying, ‘My seatbelt hurts my abdomen so I’m not going to wear it,’” said Brown.

Myth #4: I don’t need sunscreen because there’s SPF in my makeup.

Brown said if your makeup is at least SPF 30, then you’re covered for about two hours.

After that, it’s time to apply or reapply sunscreen. Be sure to cover all exposed parts of your body, not only your face.

Myth #5: Sunscreen never goes bad.

“Ingredients in sunscreen that offer protection do wear out,” said Brown. “Always check the expiration date.”

How to protect yourself and the environment

Brown said if you’re worried about sunscreen impacting the ocean, go with a mineral-based option.

He also recommends wearing a wide-brimmed hat and long-sleeved shirts for extra coverage when possible.

“The biggest spot missed is the upper back. It’s always valuable to have someone put sunscreen on your back where you can’t reach. Don’t forget the ears,” said Brown.

The physician said ultimately, sunscreen should always be a part of your daily routine.
